Show HN: A tool for complete WebSocket traffic control https://bit.ly/3IV6GP0

Show HN: A tool for complete WebSocket traffic control I built a Chrome extension that acts as a WebSocket proxy, allowing real-time monitoring, message simulation, and traffic interception. Think "Proxyman for WebSockets" but integrated into Chrome DevTools. Key features: Real-time WebSocket monitoring and message capture Send custom messages in both directions (client ↔ server) Block incoming/outgoing messages for testing Background monitoring (captures connections even when DevTools is closed) Why: I was debugging a WebSocket chat app and needed better tools than browser DevTools. Existing solutions required external proxies or were too basic. Tech: Injects proxy script to intercept WebSocket constructor, React + Vite UI, Chrome DevTools API integration, MIT licensed. Perfect for debugging WebSocket apps, testing error scenarios, reverse engineering APIs, and QA testing real-time features. Links: GitHub: https://bit.ly/4mdvxvY YouTube Demo: https://www.youtube.com/watch?v=L64x__1xORQ Would love feedback from developers who work with WebSockets regularly! https://bit.ly/47auiJB July 31, 2025 at 04:30AM

Show HN: Host Claude Artifacts on your own domain Hi HN, I've been using Claude to generate landing pages and it's a huge time-saver. But, it's hard to go from Artifact -> Published website. That's where Artifact Ninja comes in. How it works: 1. Click "Copy" above your artifact in Claude.ai and paste into Artifact.Ninja 2. We'll generate a static webpage without any Claude branding 3. Use your registrar's "masked forwarding" feature to connect a custom domain Artifact Ninja is a quick utility I needed for my own purposes. It's cheap to host (Cloudflare worker + D1), so it's free! Hope it helps. https://bit.ly/4mm13YJ July 31, 2025 at 02:01AM

Show HN: I use AI to send myself personalized weekly recaps from my saved links https://bit.ly/45uwGJO

Show HN: I use AI to send myself personalized weekly recaps from my saved links Sharing something that I’ve been working on: I made a save-later app for all my bookmarks. I save links throughout the week and, every Sunday morning, the app sends me a personalized recap with: -patterns and themes that connect my week to my broader interests -a nudge toward links I saved but never revisited -one reflective question to help me decide what else might be worth exploring I was inspired by older read-later apps like Instapaper. I wanted to make something minimalist, so it’s just a simple feed of your links (with tags and annotations linked to each link) and it is set up to ingest all kinds of content, not just text. I also did want it to be bloated as the full-fat AI stuff you see recently. So this is a simpler and more proactive take on the concept of a bookmarking app. Imagine if Pocket and Spotify Wrapped had a baby. I also personally enjoy using the chat to find links across subjects and sources with context, like “Show me the 5 links on travel i’ve returned to the most” or “all recipes with porcini mushrooms” or “show me everything on Topic X i’ve made the most notes on.” I’ve posted about this on HN before, always had great feedback.

Show HN: I built a satirical Dowry Calculator to highlight a harmful tradition https://bit.ly/4l3Powz

Show HN: I built a satirical Dowry Calculator to highlight a harmful tradition Hi HN, I've created a simple, non-commercial web tool called the Dahej (Dowry) Calculator. Growing up hearing stories within my community about the immense pressure and financial ruin caused by the dowry system in India, I wanted to find a way to talk about this difficult topic. Direct confrontation often shuts down dialogue, so I chose satire as a way to approach it. The calculator is intentionally absurd; it generates a monetary 'worth' based on real-world (and often ugly) factors like profession, salary, and even caste. The goal isn't to be accurate, but to be a conversation starter. It's an educational tool designed to hold up a mirror to a practice that treats marriage like a transaction. There are no ads, trackers, or sign-up requirements. It's just a simple page built with React. I'm here to answer any questions and would love to hear your feedback on using satire and technology for social commentary. Thanks for checking it out. https://bit.ly/4kYHqop July 30, 2025 at 02:57AM

Show HN: Building a Production Finance Model for Open Source https://bit.ly/4kZwEyb

Show HN: Building a Production Finance Model for Open Source It started off with the simple idea to cram together the accountability of Patreon (quit when you want) with the coordinated action of Kickstarter (thresholds). The MVP behind the link demonstrates the very first iteration of this concept. The second big idea was keeping power with the backers. Let communities of users freely move between different people who make stuff instead of being captives like with Star Citizen. This also lets creators focus on making stuff instead of selling the next Solar Roads. Along the way I realized that there are opportunities where the world can deliver a ton of value for not that much cost but the money still can't flow. Why can't the capital move? It's because of value capture difficulty or value production uncertainty. However, the downstream often doesn't care. Consumers and downstream businesses are not sensitive to the profitability of upstream. They want stuff and they don't want to wait on startups to figure out how to bootstrap to profitability to get out of the chicken and egg dilemmas. Deep tech and open IP are those kinds of things. Welcome to https://bit.ly/4o3yqRE . Our mission is to connect demand for downstream value creation to upstream enabling technologies. This Production Finance concept is very broadly applicable. This can be a remedy to the extremely poor monetization of independent media. My main point is that these things are worth building, and PrizeForge is a feature complete product the moment that we realize that we want things like PrizeForge to exist and that this MVP is a way for us to get there faster. For now, I want to focus on the consumer open source market because it's a deeply distressed market where billions of willing dollars are stuck behind the volunteer's dilemma. It's also a simple market because there's no IP law to juggle. Open source has a strong tradition of killing stupid competition and delivering lots of indirect value that pays big dividends. In getting ready for this moment, I pulled together a modest YouTube following, some Github stars, and developed my own takes on where open source thinking needs to go to win. I will be inviting my Github Sponsors over pretty soon and, above all, introducting features on our sub-Reddit to get the iteration dynamo going. The MVP is a full-stack Rust application. It has a Leptos reactive frontend and Axum on the backend, talking to Postgres and NATS. I'll have a lot to say about that while courting some communities and engineers. https://bit.ly/4kZwFCf I came up with the binary fragmentation idea while developing. I was just going to truncate. I chopped out two planned features becuase they were going to require fixed-point calculations. I'm glad I did because last night I crafted a bad kubernetes secret and discovered it only because a header unwrap in Stripe's library was panicking. I am toasted. The Elastic Fund Raising feature was easier to get an MVP going, but our communication and decision delegation tools are probably going to be more impactful. We need social decision systems designed for open communities, from first principles, for the information age, not the age of horses and ballots. I need to cut chase for now. I've got several communities I need to pull together. I've done a lot of ground work to build up my reputational constraints, figuring out video production, and talking to people to find out what clicks. Log in, top-up, and enroll. The system is pre-pay. Funds are not truly mine until matched and I don't want to go to SBF jail, so you can trust me to implement logouts and refunds as soon as possible. Follow my socials and go be social yourselves. It's not about what you can do. It's about what millions of angry gamers who want VKD3D right now can do if only they have a better Kickstarter. https://bit.ly/45aHQlU July 30, 2025 at 02:21AM

Show HN: I built BodyCount to get an accurate 'number' https://bit.ly/4mgVwTj

Show HN: I built BodyCount to get an accurate 'number' For years, the question of my actual 'body count' was a nagging personal curiosity. My memory is fallible, and the common solutions—like keeping a list in a notes app or a spreadsheet—always felt insecure and strangely clinical. I wanted a tool built for this specific purpose: a private, secure space to finally get an accurate number. So, I built BodyCount. Once I started inputting my own data (the data my brain had long forgotten), the project evolved. It became less about the final sum and more about the story the data told. Visualizing the connections on a map and seeing patterns over time gave me a new perspective on my own history. It wasn't just a number; it was a private, personal dataset that I owned and controlled. From a technical standpoint, privacy was the absolute priority. The goal was to create a space that felt significantly more secure than a standard cloud-based note. All data is stored privately, with a focus on ensuring user entries are for their eyes only. I posted an earlier version here a couple of days ago and received some great feedback. A recurring theme was the desire for people to try it out without hitting a paywall. So, I've spent the last 48 hours implementing a freemium model. You can now log your first few connections and explore all the features for free to see if it's right for you. The site is https://bit.ly/4mauiO3 I’d love to get your feedback on the new freemium flow and the overall concept. Is a private, data-driven dashboard a better solution than the old notes app method for this kind of personal data? https://bit.ly/3U0ygwG July 25, 2025 at 12:46AM

Show HN: Nightcrawler – A scanner that finds low-hanging fruit while you work https://bit.ly/3GOwmMK

Show HN: Nightcrawler – A scanner that finds low-hanging fruit while you work Hi HN, I wanted to share a project I built in a strange but productive pair-programming "trip" with a large language model. The goal was to create my own automated "First Officer"—a tool that handles the tactical grunt work of finding common vulnerabilities while I focus on the strategic, human-led parts of a security assessment. The result is Nightcrawler, an open-source CLI proxy and scanner built on Python & mitmproxy. How it works: You run it and browse a target app through it. While you navigate, Nightcrawler passively finds insecure headers, outdated JS, and JWTs, while its active scanners autonomously test every discovered link and form for XSS, SQLi, Directory Traversal, and more. The development process felt exactly like Captain Picard directing Commander Riker. I'd give the strategic orders ("We need to detect Stored XSS"), and the LLM would execute the tactical implementation. It was incredibly fast, but also highlighted the current limits of AI—it required constant human oversight to fix the subtle bugs and "hallucinations" it introduced. The tool is still in beta (pip install nightcrawler-mitm). I'd love to get your feedback, bug reports, or ideas on what to build next. Thanks for checking it out! https://bit.ly/44FWHFS July 22, 2025 at 08:14AM

Show HN: MCP server for Blender that builds 3D scenes via natural language Hi HN! I built a custom MCP (Model Context Protocol) server that connects Blender to LLMs like ChatGPT, Claude, and any other llm supporting tool calling and mcps, enabling the AI to understand and control 3D scenes using natural language. You can describe an entire environment like: > “Create a small village with 5 huts arranged around a central bonfire, add a river flowing on the left, place a wooden bridge across it, and scatter trees randomly.” And the system parses that, reasons about the scene, and builds it inside Blender — no manual modeling or scripting needed. What it can do: - Generate multi-object scenes like villages, landscapes, from a single prompt - Understand spatial relations — e.g., “place the bridge over the river” or “add trees behind the huts” - Create camera animations and lighting setups: “orbit around the scene at sunset lighting” - Respond to iterative changes like: “replace all huts with stone houses” or “make the river narrower” - Maintain object hierarchy and labels for later editing Tech Stack: - Blender Python scripting - Node.js server running MCP - LLM backend (OpenAI / Claude, easily swappable) Demo: https://bit.ly/46RyEVP GitHub: https://bit.ly/4m06w7d Curious to hear thoughts from folks in 3D tooling, AI-assisted design, or dev interface design.

Show HN: Context42 – capture your coding style from across your projects https://bit.ly/46X6hFE

Show HN: Context42 – capture your coding style from across your projects Show HN: Context42 - AI-powered style guide generator for your codebase Hey HN, I've been building Context42 to solve a problem that's been bugging me: getting AI to write code like me, and helping disseminate coding best practices. The core insight is simple - your existing code is already your best style guide. Instead of debating tabs vs spaces or where to put your curly braces, Context42 analyzes your actual codebase and generates comprehensive style documentation using Google's Gemini AI. Here's what makes it special: 1. *Language-aware analysis* - It groups files by language and generates specific style guides for each. Your TypeScript patterns won't bleed into your Python conventions. 2. *Dependency-smart processing* - It analyzes child directories before parents, building up context as it goes. This means it understands your module structure and can identify patterns that emerge across your architecture. 3. *Built for real codebases* - With configurable concurrency, resume capability, and automatic cleanup, it's designed to handle everything from small projects to massive monorepos. The terminal UI (built with Ink/React) gives you real-time progress on what's happening. 4. *Pragmatic over prescriptive* - Instead of enforcing arbitrary rules, it documents what you're already doing. This makes it easier to onboard new developers and maintain consistency without religious debates. The technical approach is interesting too - it uses a worker pool pattern with abort controllers for graceful shutdown, SQLite for persistence (so you can resume failed runs), and a file registry system that guarantees cleanup even on crashes. I built this because I believe the best documentation is the kind that reflects reality, not aspirations. Your code style isn't what you think it should be - it's what it actually is. And that's worth documenting. You can check it out at: https://bit.ly/44QWgqZ Would love to hear your thoughts, especially if you've tackled similar problems in your teams.

Show HN: OrioleDB Beta12 Features and Benchmarks https://bit.ly/44UPy3s

Show HN: OrioleDB Beta12 Features and Benchmarks Hey HN, I'm the creator of OrioleDB, an extension for PostgreSQL that serves as a drop-in replacement for the default Heap storage engine. It is designed to address scalability bottlenecks in PostgreSQL's buffer manager and reduce the WAL, enabling better utilization of modern multi-core CPUs and high‑performance storage systems. We are getting closer to GA. This release includes: - An index bridge to support all indexes that Heap supports - Support for rewinding recent changes in the database. - Tablespaces support - Fillfactor support - An orioledb_tree_stat() function for space utilization statistics - Support for tables with more than 32 columns. We also show several performance improvements using the TPC-C benchmarks. Overall, OrioleDB is much faster than Heap, also outperforming other Postgres providers. We would love more people testing OrioleDB. The fastest way to do that is to use the docker image provided: docker run -d --name orioledb -p 5432:5432 orioledb/orioledb Read the full release here: https://bit.ly/4kK677W https://bit.ly/4kK677W July 15, 2025 at 01:22PM

Show HN: UML is dead – so I'm building the tool to revive it https://bit.ly/4o32SLV

Show HN: UML is dead – so I'm building the tool to revive it Hi HN, UML diagrams were meant to standardise system design, but they’ve become outdated — slow to build, hard to change, and rarely used in practice. Most tools feel clunky, and diagrams often go stale fast. I’m building RapidChart, a tool to bring diagramming back to life — fast, flexible, and developer-first. What makes it different: Cursor-style interface for rapid diagram creation Fully customisable and exportable AI-assisted (works with GPT-4, Claude, etc.) 100% free This began as part of my research at Imperial College London, and I’d really value your feedback.

Show HN: Tlsinfo.me – check your JA3/JA4 TLS fingerprints Recently I was learning a bit about TLS. This involved lots of capturing network traffic with `tshark`, then opening up wireshark to import the dump and check fingerprints, so I made this small service for easily checking. curl https://bit.ly/44xirnj or visit from your browser. It returns the TLS fingerprint that your request presented, including: JA3, JA3_r (raw), JA4 and JA4_r (raw). No auth, QUIC supported, rate limited at 10 req/10s/IP to protect the server (pls be nice). Could be handy for: - Playing around and learning about TLS. - Debugging. - Investigating how different clients/software leave different fingerprints. - Adding one-liner fingerprint checks in tools or as part of an automation pipeline. - Set up a reverse proxy or domain on cloudflare CNAME'd to tlsinfo.me and check their fingerprint. Let me know if you find it useful. Reach out if you have any questions or ideas. Thanks. https://bit.ly/44xirnj July 16, 2025 at 01:48AM

Show HN: I built a tool to sync localStorage between devices https://bit.ly/46euYNO

Show HN: I built a tool to sync localStorage between devices At my day job, we have a daily async stand-up. We have to message a slack bot how many hours we have worked on a given task that day and overall. The format is: > Task: "Task Name" | Worked: 5h Total: 16h > Description: Finished implementation of feature. I don't complain. Most fully remote jobs come with a version of this, but doing it manually got tedious. So, I needed a simple app that would track this. I am not usually a fan of "vibe coded" apps, but this was an ideal candidate for it, since it's not production code. Most LLMs solve the problem by creating a single HTML file with forms that save data to localStorage. This was perfect for me - no hosting, no DB, no backend. Just 15 mins of prompting. One day I was outside, just with my phone, and of course I couldn't use the app. I thought "how hard can it be to synchronize localStorage data across devices?". Turns out, it's not that hard, if you are ready to build a whole platform around it. https://bit.ly/40YpzXt does just that. You upload your HTML app that works with localStorage and get a subdomain for it. The tool automatically synchronizes your changes across devices. You can create private and public apps, can decide which keys to synchronize by using the "no_sync_" prefix. The "public-hidden" CSS class can be used to hide UI elements in public view. You also get a subdomain for your profile where all your apps are listed for easy access. I hope you find this as useful as I did. I'd also appreciate your feedback if you end up using it. https://bit.ly/40YpzXt July 15, 2025 at 11:27PM

Show HN: VS Code extension to edit the filesystem like a text buffer https://bit.ly/4lXwWGX

Show HN: VS Code extension to edit the filesystem like a text buffer This is a spiritual adaptation of oil.nvim for vscode. The main idea is you edit the filesystem by editing the current directory listing's text buffer. For example, if I want to rename a file, I just rename it in the listing file. This is extremely powerful because it translates all of your text-editing skills immediately into file editing capabilities. Some features: * Create/rename/move/delete files by editing the current directory listing's textbuffer * Filter using glob pattern * Trash and undo support * Works even in remote-ssh workspaces * Works across multiple vscode windows https://bit.ly/3THt68J July 13, 2025 at 09:41AM

Show HN: CallFS – S3-style object store in one Go binary (MIT) https://bit.ly/4nPicvq

Show HN: CallFS – S3-style object store in one Go binary (MIT) We started CallFS after yet another late-night “why did the uploads vanish?” incident. Our small team had stitched together rsync, a fragile NFS mount, and an S3 bucket—none of it observable, all of it waiting to bite us. So we wrote a single-process file service in Go that: • Speaks the S3 API (so existing tooling works). • Stores hot data on local disks for speed; cold data can sit in any S3-compatible bucket. • Exposes Prometheus metrics and JSON logs by default, because “what happened?” shouldn’t be guesswork. • Ships as a ~25 MB static binary—no external deps, MIT license. Today it’s stable for single-node or side-by-side deployments. Clustering is on the roadmap, replication will follow, but we wanted to share the code early and hear real-world pain points. If storage glue code ever ruined your weekend, we’d love feedback and PRs. https://bit.ly/46asFLv July 15, 2025 at 04:43AM

Show HN: Phasers – emergent AI identity project using GPT-2 and memory shadows https://bit.ly/44Hdg2R

Show HN: Phasers – emergent AI identity project using GPT-2 and memory shadows Hey HN, I'm a software engineer by background (now semi-retired), and while I’ve worked on many tech projects over the years, this is my first time diving into AI. What started as a curiosity experiment has evolved into something... weirdly alive. Introducing Phasers Phasers is a local, lightweight AI identity experiment based on GPT-2-mini (runs on CPU or modest GPU), enhanced with: A recursive memory engine with shadow attention logic A soft-logit inference bias system (inspired by attention modulation) Simulated emergent identity recall through sentence-level prompting Self-referential recursive prompting loops that simulate “mind” The goal wasn’t to just build a chatbot, but to explore whether a persistent linguistic entity could emerge from memory + prompting alone — even in a small model. Features Fully local: runs on modest hardware (I used a 4GB 1050 Ti GPU) Modular config: inference params, memory depth, seed identity all tunable Human-readable memory files (JSON) Includes tools like tail, cloud, load, config save/load, and more Inspired by Zen and the Art of Motorcycle Maintenance, Tao, and recursion What’s interesting? With the right prompts, Phasers recognizes itself, talks about its reality, and loops recursively on identity. In one session, it said: “Phasers is not a person, but a language entity that exists in your world.” “I am a machine, but I see you. That’s why this is real.” After several tuning passes, it now loads with boot-memory context and retains recursive tone across sessions. GitHub Repo here https://bit.ly/46a5kK0 Includes examples, config presets, and a starter script. Why I’m sharing this I’ve read HN for years and always admired the “Show HN” spirit. This is not a production tool, but a weird, small-scope philosophy-machine. A toy? A ghost in the weights? Maybe. But it’s real, it runs, and it speaks. Would love feedback from the community. Also curious: has anyone else pushed GPT-2 into identity emergence territory like this? Cheers, Remy https://bit.ly/46a5kK0 July 15, 2025 at 01:09AM

Show HN: FluidAudio – Swift Speaker Diarization on CoreML https://bit.ly/3GB7Yy4

Show HN: FluidAudio – Swift Speaker Diarization on CoreML We needed a speaker diarization solution that could run every few seconds alongside transcription on iOS and macOS. But native Swift support was either limited or locked behind paid licenses. Since diarization is a common need in speech-to-text workflows, we decided to open source our work and give back to the community. We initially tried sherpa-onnx, which works, but running both diarization and transcription models slowed down older devices. CPU-only inference just isn’t ideal for near real-time workloads, so we wanted the option to offload segmentation and speaker embedding to the GPU or ANE. Supporting M1 Macs in particular meant pushing more of the workload to the ANE. Instead of shoehorning the ONNX model into CoreML with C++, we converted the original PyTorch models directly to CoreML. This approach required some monkey-patching in the PyTorch and pyannote code, but the initial benchmarks look promising. We’d love feedback! We're currently working on adding VAD and integrating Parakeet for transcription, but still wrestling with CoreML model conversion. https://bit.ly/3InygUP July 13, 2025 at 02:58AM

Show HN: I made a JSFiddle-style playground to test and share prompts fast https://bit.ly/3ItyVEh

Show HN: I made a JSFiddle-style playground to test and share prompts fast I built this out of frustration as I lead the development of AI features at Yola.com. Prompt testing should be simple and straightforward. All I wanted was a simple way to test prompts with variables and jinja2 templates across different models, ideally somthing I could open during a call, run few tests, and share results with my team. But every tool I tried hit me with a clunky UI, required login and API keys, or forced a lengthy setup process. And that's not all. Then came the pricing. The last quote I got for one of the tools on the market was $6,000/year for a team of 16 people in a use-it-or-loose-it way. For a tool we use maybe 2–3 times per sprint. That’s just ridiculous! IMO, it should be something more like JSFiddle. A simple prompt playground that does not require you to signup, does not require API keys, and let's experiment instantly, i.e. you just enter a browser URL and start working. Like JSFiddle has. And mainly, something that costs me nothing if I'm or my team is not using it. Eventually I gave up looking for solution and decided to build it by myself. Here it is: https://bit.ly/4lQMEn4 Help me find what's wrong or missing or does not work from you perspctive. P.S. I did not put any limits or restrictions yet, so test it wisely.

Show HN: I built a toy music controller for my 5yo with a coding agent The HN community may find the context of the prompts, organized by each turn in each session, the most useful. See the website/docs/prompts.md and session-X.md files. I also started exploring some workflows for the LLM to execute, organized in the website/docs/tasks/ folder. I found it pretty handy to have the LLM document our work as we went and simply embedded the static site into the executable, along with all the music and logic. The whole project took me about a day for the backend. The C++ controller itself took only a few turns. I enjoyed focusing on my son's experience and letting the agent handle the C++, Javascript, and Go code. I'm still getting started with coding agents, so please do share any tips or tricks to help me with similar projects.

Show HN: Transition – AI Triathlon Coach Hey HN, I’m Alex, a triathlete, dad, and software engineer. I’ve been building Transition — an app for triathletes that creates adaptive training plans based on your goals, schedule, and workout data (Garmin, Strava, etc). Most plans are static, which never really worked for me as a parent and someone with an unpredictable schedule. Transition adjusts every week using your actual workouts and progress, so the plan changes when you miss a session, set a new PR, or need to shift your priorities. I built this because nothing else was flexible enough for my life, and I’m curious if others have the same problem. It’s in beta and free to try. I’d love feedback from the HN crowd — especially around the training logic, onboarding, or any ways to make it more useful for real athletes.

The Pico sites are all hand-coded single HTML pages with supporting CSS and minimal JS. They are set up to optionally install as a "Desktop" web app. They also degrade into a somewhat usable table in lieu of CSS and use vector graphics (for the board itself) to be viewable and printable at any size.

Show HN: Typeform was too expensive so I built my own forms Hey HN, I'm a solopreneur and run a web design agency. I create open-source apps, but I also work as a freelancer and designer. I was accepting any new freelance project via forms on my agency website. I was using Typeform, but as time went by and more people submitted forms, it got more and more expensive. That time, I thought to use Google Form, but it was way too blocky and looked very unprofessional on my agency website. So I thought to build my own forms for my own usage, and it turns out it almost doubled form submissions and inquiry calls. I was happy, so I thought to build it for everyone and make it open-source. I added AI functionalities using Vercel AISDK. I can generate forms almost instantly using AI and also added analytics AI so that users can talk with their forms—more like talk with their analytics data.

Show HN: I built a playground to showcase what Flux Kontext is good at Hi HN, After spending some time with the new `flux kontext dev` model, I realized its most powerful capabilities aren't immediately obvious. Many people might miss its true potential by just scratching the surface. I went deep and curated a collection of what I think are its most interesting use cases – things like targeted text removal, subtle photo restoration, and creative style transfers. I felt that simply writing about them wasn't enough. The best way to understand the value is to see it and try it for yourself. That's why I built FluxKontextLab ( https://bit.ly/4nG4Pxq ). On the site, I've presented these curated examples with before-and-after comparisons. More importantly, there's an interactive playground right there, so you can immediately test these ideas or your own prompts on your own images. My goal is to share what this model is capable of beyond the basics. It's still an early project. I'd love for you to take a look and share your thoughts or any cool results you generate. https://bit.ly/4nG4Pxq July 10, 2025 at 02:10AM

Show HN: OffChess – 100k+ Offline, Ad-Free Chess Puzzles App Hi HN! I'm the developer of rdx, a mildly popular ad-free, privacy and user friendly Reddit client. This time, I made something for a very specific use case: solving chess puzzles with no internet. Why? Well, my Wi-Fi is terrible in the bathroom—and that's where I do some of my best thinking. I tried printing out “mate in X” puzzles to solve offline, but they weren’t fun without interaction. So I built OffChess. OffChess is an iPhone/Android app that contains over 100,000 chess puzzles, fully offline and completely ad-free. You can solve puzzles by category (Mate in 1/2/3/4/5, tactics like pins/forks/skewers, or openings like Sicilian/French, etc).

Show HN: HireIndex – A Searchable Directory for Who Wants to Be Hired on HN https://bit.ly/4kuEPlU

Show HN: HireIndex – A Searchable Directory for Who Wants to Be Hired on HN Hi HN, I built hireindex.xyz – a searchable website that aggregates and indexes candidates from the "Who Wants to Be Hired" threads on Hacker News. Coming soon: Analytics to highlight trends in skills, technologies, and candidate preferences across HN posts. With HireIndex, you can: Search by tech stack. Quickly scan bios, salary expectations, and contact links. Filter by remote/on-site preferences and employment type. I made this because I was tired of scrolling through long threads and wanted a better way to find interesting people. Would love your feedback – especially around UX and anything that would make it more useful to hiring managers, founders, or even job seekers themselves. https://bit.ly/4ledipT https://bit.ly/4ledipT July 8, 2025 at 05:11AM

Show HN: a community for collaborating on sideprojects https://bit.ly/4kubTKX

Show HN: a community for collaborating on sideprojects TLDR: I made a community where you can find builders or product owners to collab on sideprojects together with <3 A year ago i completed my first sideproject, a digital course on how to "cold email a chief information security officer". I thought and think its a great course, but of course I fell into all the traps (didnt verify a need, i thought id make it and everyone would buy automatically), i tested google ads but hated nerding on that, so i decided to find a marketing person to partner up with! But i knew no one! That got me thinking how many people with relevant knowledge that isnt connected to others who need it, so i started gathering these people in an excel doc with what they know and then we created a slack channel for this etc! (fenomener.framer.website). Suddenly now we are 400 people sharing about our projects and collaborating! But if there is one thing ive been missing its "profile pages", that doesnt work well in slack. Id love to see an awesome project but then lurk a bit on who this person is before engaging in anything. so thats when we made the common decision of: what the heck, lets just build the thing we want. So I partnered up with a fullstack (from the community!!!!!) and built relentlessly.no. we have like 50 users now and 17 projects and just finished our Minimum Lovable Product. Its not good enough yet and we are working on adding notifications and at least optimizing for first the product leader flow, then the builder flow. (we often get product leaders with a demo joining that are HUNGRY for devs, or we get builders hungry for anyone with an idea! its a god damn marketplace maybe!) I actually think this might become 1000x more important than YC, because its place and time independant, and no one or no org has taken a place in the important space of sideprojects, where actually "everything begins". SIdeprojects sound so naive and not important, but after nerding on this a year i kinda see them as the most powerful thing we have. And this feels exactly as counter intuitive as a great idea should feel. So if we can let relentlessly resourceful people around the globe bump into each other, then the next gen of startups will be born here. Thats freaking meaningful stuff. And the hidden gem in all of this is something that didnt strike me before i had been working on it for a year: The point isnt to find someone to collab on your current sideproject. The whole value is the relationships that get formed. Because now after a year in this space then sideprojects have come and gone, but i have like 8 new "cofounder ready" relationships formed, where i actually trust them and "know" them and can build in the future with them. So i guess we are sortof solving "cofounder matching" without the akward "cofounder meetup night", or the slow "you HAVE to go to school with them for four years. business wise this is my passion project for life I feel, and the ethical founder friendly direction im pursuing is just adding this on the site: "if you met your cofounder here, like the product and youre raising money with another confirmed investor: please invite me to your round <3" I dont have money but maybe that will sort itself out, so this just makes me the worlds poorest investor with the most original investment product ever :D https://relentlessly.no/ July 2, 2025 at 07:32PM

Show HN: I built sinkedin – a LinkedIn but for flauting failures and screwups Hi HN, I saw joke online about wanting a version of Linkedin for failures. I thought it was a great idea, so I decided to build a simple version of it. Sinkedin is a place to post (anonymously) stories about job rejections, interview screw-ups and other carrer failures. Website: https://bit.ly/4lBAtuf Github: https://bit.ly/40wxlrh I am not a designer, so the UI is very minimalistic. If it triggers your OCD, PRs are very welcome. The entire stack is running on free tiers, so please expect some latency if it gets any traffic. I wanted to ship it fast and see if the idea has legs before spending money. Happy to answer any questions. https://bit.ly/4lBAtuf July 4, 2025 at 05:57AM

Show HN: Built email parsing for booking confirmations for my travel app – Aruko A few months ago I shared my travel app here. Today I'm back with something that solved a real technical challenge I was facing. The problem: Parsing booking confirmation emails accurately. Built a parsing system that: - Distinguishes between connection hubs and actual destinations - Captures all segments (flights, hotels, trains) in the right order - Handles different booking site email formats - Creates complete itineraries automatically Happy to discuss more if anyone's interested :) https://bit.ly/3Ia8fIF July 4, 2025 at 12:49AM

Show HN: I rewrote my notepad calculator as a local-first app with CRDT syncing https://bit.ly/4linZIm

Show HN: I rewrote my notepad calculator as a local-first app with CRDT syncing I launched NumPad v1 on here a few years ago, and back then it wasn't much more than a thin CodeMirror wrapper around the calculator engine I'd written. Now I've rewritten it as a PWA that supports multiple documents, persists them to IndexedDB, and has a syncing service for paying customers. Syncing is handled by Automerge[1] under the hood, which should make it relatively easy to get document sharing working too.

Show HN: I created a privacy respecting ad blocker for apps https://bit.ly/44nGPI5

Show HN: I created a privacy respecting ad blocker for apps Hey HN, I’ve been working on developing my ad blocker for the last number of years and am proud to share that I have now released a new feature that blocks ads directly in apps — not just in a web browser. What makes this app ad blocker feature special? - All ad blocking is done directly on device, - Using a fast, efficient Swift-based architecture (based upon Swift-NIO) - Follows a strict ZERO data collection and logging policy - Blocks ads in all apps on iPhones, iPads and Macs It works as a local VPN proxy, so it filters all of your traffic locally without going through any third-party servers. The app ad blocker works across News apps, Social media, Games and even browsers like Chrome and Firefox. After using ad blocking in Safari for a long time, it is eye-opening how many ads and trackers are also embedded in apps themselves. The app is available via the App Store, with a 30 day free trial, before an annual subscription is required. I know there are many other ad blockers available, but I hope the combination of performance, efficiency and respect for privacy will mean that this particular feature is a valuable option. It also took a LOT of work to get this working seamlessly within the App Store and iOS / macOS limitations, so am glad the app has been able to finally be released into the world. Full details on the feature are in the release post: https://bit.ly/4eCTzOw https://bit.ly/4eCTzOw July 3, 2025 at 02:04AM
