Show HN: Simple to build MCP servers that easily connect with custom LLM calls https://bit.ly/42EqdeE

Show HN: Simple to build MCP servers that easily connect with custom LLM calls Hi! After learning about MCP, I'm really excited about the future of provider-agnostic, re-usable tooling. Unfortunately I've found that while it's easy to implement an MCP server for use with tools that support it (such as Claude Desktop), it's not as easy to implement your own support (such as integrating an MCP server into your own LLM application). We implemented a thin MCP wrapper that easily integrates with Mirascope calls so that you can hook up an MCP server and client super easily to any supported LLM provider. Excited to see what people build with this! https://bit.ly/42yIWrX February 1, 2025 at 01:50AM

Show HN: 150+ products launched in 7 days on this fair Product Hunt alternative https://bit.ly/4hBPIl0

Show HN: 150+ products launched in 7 days on this fair Product Hunt alternative A little over a week ago, I was wondering if anyone would care about the thing I’d just built. Let me rewind a bit. I’m a solo indie maker, just like a lot of you. I’ve built so many projects, put in the work, and then… nothing. A few months ago, I launched something I was genuinely proud of on one of the big platforms. I was excited, hopeful. But within hours, it got buried under a pile of other launches. No one saw it. No one cared. That sucked. Not because I expected it to blow up overnight, but because it felt like I never even had a shot. And I kept thinking about how many other indie makers feel the same way? So, I decided to build something different. I coded for four days straight, juggling my 9-5 job, running on no sleep, and a lot of self-doubt. But I kept going because I believed in the idea: a platform where indie makers could get a fair shot. The idea was simple (but powerful as I see it): • 10 launches per day, max. Every product gets its moment in the spotlight. • 2 votes per user, per day. Quality over quantity. • An "Under Radar" feature to give overlooked products a second chance. • A randomized product list to ensure fair exposure and reduce voting bias. I posted about it here on Hacker News and on X, half-expecting crickets. But something incredible happened. Within hours, indie makers just like you and me started scheduling their products. And in just 7 days, over 150 products were scheduled to launch on the platform. Every time a new product is scheduled on ItsLaunched, I'm reminded why this platform needs to exist. These are products that deserve to be seen. I'm not sharing this to boast, but to thank this community. Your support, your feedback, and most importantly, your willingness to give a platform like this a chance, means the world to me. I’m still tweaking and improving the site every day based on feedback. It’s far from perfect, but it’s growing. So, if you're a maker with a product you're stoked about, come check us out at ItsLaunched.com and if you've already launched with us, a huge thank you. You're the reason this thing exists in the first place. As for me, I'm just a maker trying to create something that makes a difference. And thanks to this community, I feel like maybe, just maybe, we're doing exactly that. Here's to the makers and the dreamers. Keep building awesome things. We'll be here to make sure the world sees them. January 31, 2025 at 04:48AM

Show HN: 1M+ animated GPU sprites in JavaScript https://bit.ly/4aMmDBa

Show HN: 1M+ animated GPU sprites in JavaScript We added a new feature to our open-source HTML5 game engine today that allows you to create Sprite GPU Layers. These pack together simple JS object definitions onto the GPU and renders them using a custom vertex shader. This skips all CPU computation and GPU upload operations, resulting in vastly increased performance. For objects that don't need to be updated by input, physics, or other interactive behaviors, we found it to be a great solution. In testing, we've easily managed to blast millions of sprites around on moderate desktop-grade GPUs. Indeed, we hit the fill rate limitation of the GPU far sooner than we hit any other type of limitation. But as with all hardware-related things, ymmv. Frankly, we'd love to get our hands on a 5090 to see what we could do. The link includes 4 demos to play with, and the full source is on GitHub and npm under the MIT license. https://bit.ly/40ANtY5 January 31, 2025 at 02:52AM

Show HN: I created an AI app that creates endless language learning scenarios I created LinguaLearn.ai to solve the repetitiveness of traditional language learning methods. It generates dynamic conversation practices across 30+ languages (including less common pairs like Korean→Spanish), with customizable scenarios and difficulty levels (A1-C2) delivered in WAV format accompanied by a transcript. The courses are similar to those produced by the Foreign Services Institute in the mid-20th century, which are very effective. Tech stack highlights: - Natural conversation generation in any scenario - Cross-language learning support (learn any language from any language) - Infinite number of scenarios (you can be really specific and i.e. try "restoring antique barometers from the Victorian era" or for a laugh you can try "falling out of plane and encountering amazon women"). - High-quality audio generation - Difficulty-aware content generation (CEFR levels A1-C2) - Full transcript generation Currently in beta, offering 5 free lessons/month.

Show HN: Puck 0.18 adds drag-and-drop for CSS grid and Flexbox https://bit.ly/42uTHLY

Show HN: Puck 0.18 adds drag-and-drop for CSS grid and Flexbox Hey HN! I just released Puck 0.18 with a new drag-and-drop engine for CSS grid and flexbox support. You can now use Puck to create a page builder that behaves like a design tool, but embedded within your own app and using your own React components. To use it, just add `display: flex` (or grid, etc) to your DropZone and Puck will gracefully handle drag-and-drop across all dimensions. Shout out to the dnd-kit maintainer Claudéric for the collaboration and support (if you’re reading this, I just sponsored you on GitHub!) and as always, a huge thanks to my wonderful community for all the testing and feedback. It would not be possible without you! If you've not heard of Puck, it's is an open-source visual editor for React that I maintain, available under MIT so you can safely embed it in your product. Some background: This is the culmination of 18 months of iteration, and has required several breakthroughs in drag-and-drop to achieve: drag-and-drop across iframes, accounting for layout shift across nested components, and natural collision detection are some of the problems that have kept me extremely busy. I hope to write about the process if time allows. The implementation is bleeding edge, using the experimental branch of dnd-kit with custom collision algorithms and plugins to implement a drag-and-drop experience that feels similar to react-beautiful-dnd, but across multiple dimensions. Happy to answer any questions! Will endeavour to reply to everyone. https://bit.ly/3PWTg5f January 22, 2025 at 01:39PM

Show HN: TextAI – Native SMS AI assistant for individual and group chats Hey HN community! Like many of you, I spend most of my day in text conversations. One day I found myself switching between group chats and various AI apps, and thought, why can't AI just live where we already chat? So I built TextAI. It's an AI that works right in your SMS app. No new app to download, no platform to learn. Just text +15626840069 to start chatting or add it to any group chat! The tech and stack details: - Native SMS/MMS integration with context management across conversations - Handles multiple participants, learns group preferences, and scales for concurrent chats - Able to converse in multiple languages - Built with Twilio on top of a foundational LLM model, plus building my own domain logic on top Some cool things people have used it for: - A group of my friends used it to plan a weekend trip to Las Vegas last week. It was their first time there. They used it to get suggestions on the must-do activities, casinos to play at, and finding restaurants that worked for vegetarians and meat lovers. - A high school student showed the power of AI and started a group chat with their grandpa! - my personal fav - A couple who used it to find new hiking trails around where they live without arguing for their preferences I built this because I believe AI should be accessible through existing communication channels, not locked in new apps. It should be accessible to all, and frankly, it's important to keep things simple. Hope you find it useful, and I would love your feedback, the good and the bad!

Show HN: Chat with multiple LLMs: o1-high-effort, Sonnet 3.5, GPT-4o, and more https://bit.ly/4gjqSFy

Show HN: Chat with multiple LLMs: o1-high-effort, Sonnet 3.5, GPT-4o, and more Hello HN! I was fed up switching between multiple UIs to ask GPT, Claude, etc… the same question and comparing the answers. So I built a way to ask multiple models the same question efficiently by having the LLM compare the responses and only show you new and valuable information from the 2nd model. This way you still get a fast response as normal from the 1st model, but also get any added value provided by the 2nd model. Initially I built my own UI to use this, but stumbled upon Open WebUI (formerly Ollama WebUI) which is fantastic, but is made more for local access to LLMs. So I talked to its creator, Timothy Baek, and he mentioned that security needed to be shored up before production deployment. I did some scans with semgrep, and fixed some XSRF and CORS issues along with making sure the JWT tokens, passwords, etc… were secure. This was in addition to other folks' amazing security contributions. So now we build on Open WebUI! oss ftw After launching privately a month or so ago and posting a few reddit links, I have about 100 users. We also just got access to the o1 API and provide o1-high, medium, and low effort. o1 high effort is able to solve coding problems that only o1 pro can also solve, though pro can go further and has better formatting, o1 high effort is a nice option if you don't want to fork over $200/mo. https://bit.ly/4h6Srmy... You can use o1 for free in PolyChat, which is the only place I've seen you can do so. You can also ask multiple models the same question and stream the answers simultaneously side by side. https://bit.ly/4h7DZun And you can have multiple chats going simultaneously and they will continue in the background and notify you when they're done. Another cool feature that makes long chats way easier to navigate is the overview (three dots on top right of chat) https://bit.ly/4gaxNAz We give you full control, unlike most providers, to change the system prompt, temperature, etc.. in the chat settings in the "Controls" on the top right. The formatting for code outputs and inputs is fantastic, using codemirror, and you can run code in the code blocks if it's python or JS using in-browser runtimes. You can also share chats within polychat where other logged in users can see them: e.g. https://bit.ly/3CcoNNE Or you can share it publicly to the OpenWeb UI community https://bit.ly/3E6tM2S... Finally we allow you to search and organize your chats into folders which makes finding things super fast! Infra: My custom backend that combines models and does things Open WebUI doesn't handle like token tracking is written in FastAPI and uses LiteLLM for easily accessing different model APIs. I host everything on GCP using Cloud Run for the backend and use PostGres for Open WebUI's db, along with BigQuery and Firestore for my FastAPI app's db. Pricing: Our pricing makes it cheap to access top models. It's free at first, then we offer subscription tiers starting at $5/mo which allots about ~1 million tokens per month, enough for most people. But unlike Claude's UI for example, we don't shut you down with rate limits, but rather let heavy users upgrade beyond to $10, $20, $40, $80, etc... We also suggest a plan based on how quickly you used your free tokens, so you have an idea upfront of the monthly cost before you buy. And you can upgrade or downgrade at any time. Thanks Show HN <3 https://polychat.co January 21, 2025 at 08:40PM

Show HN: I built an active community of trans people online A year ago I surveyed the internet and noticed there was only one popular space for trans and gender-non-conforming people to meet; Lex. Lex is not well liked by its users. Its software feels heavy and it is full of cash grabs and anti-patterns. It was recently acquired and is sure to only become more hostile to its users as it turns towards profit generation. With this in mind I built t4t, an alternative specially designed for not only queer people, but specifically trans people. It is an extremely lightweight service. I built it with my most ideal stack: Flutter, Svelte, Supabase, Posthog. It has grown in the last year to about 4,000 monthly active users.

Show HN: Ergonomically call LLM in bulk from CLI https://bit.ly/42gfabg

Show HN: Ergonomically call LLM in bulk from CLI Hi! I've found myself repeatedly writing little scripts to do bulk calls to LLMs for various tasks. For example, run some analysis on a large list of records. There are a few "gotchas" to doing this. For example, some service providers have rate limits, and some models will not reliably return JSON (if you're asking for it). So, I've written a command for this. What I've tried to do here is let the user break up prompts and configuration as they see fit. For example, you can have a prompt file which includes the API key, rate limit, settings, etc. all together, or break these up into multiple files, or keep some parts local, or override parameters. This solves the problem of sharing settings between activities, and keeping prompts in simple, committable files of narrow scope. I hope this can be of use to someone. Thanks for reading. https://bit.ly/4hoDjAM January 20, 2025 at 11:22PM

Show HN: Terraform Provider for Inexpensive Switches https://bit.ly/4jqI26W

Show HN: Terraform Provider for Inexpensive Switches Hi HN, I’ve been building this provider for (web managed) network switches manufactured by HRUI. These switches often used in SMBs, home labs, and by budget-conscious enthusiasts. Many HRUI switches are also rebranded and sold under various OEM/ODM names (eg. Horaco, XikeStor, keepLiNK, Sodola, etc) making them accessible/popular but often overlooked in the world of infrastructure automation. The provider is in pre-release, and I’m looking for owners of these switches to test it and share feedback. My goal is to make it easier to automate its config using Terraform/OpenTofu :) You can use this provider to configure VLANs, port settings, trunk/link aggregation etc. I built this provider to address the lack of automation tools for budget-friendly hardware.

Show HN: Deploy Docker Containers Without Setting up/Managing an Infrastructure https://bit.ly/3CgXwcO

Show HN: Deploy Docker Containers Without Setting up/Managing an Infrastructure DOrch enables Engineers, Indie Hackers, and Startups to host a docker container (OCI-compatible containers at large), without having to set up or manage a container infrastructure. It comes with features like env variables management, file sharing, FREE subdomain issuance, TLS certificate management, and automatic restart, with more features in the pipeline. The console also allows you to view logs from your containers. The product idea occurred to me about 18 months ago, while working at a different startup. The strategy of the CEO was, spray-and-pray: we created lots of products hoping one would take off. Despite being a small team working on many things, I would say we tried in terms of product quality. Our products weren't what I would consider Grade-A, engineering-wise, but they worked well for the most part. However, when it came to infrastructure, we couldn't say the same. We always had one or two things breaking every now and then. Now, you would ask, why not just use Kubernetes. Well, we thought of that. But considering how small we were and how much workload we had, there was no way we could operate Kubernetes effectively. Yes, we could have also employed a managed Kubernetes solution, but for a startup which already spends a lot on core infrastructure, due to how many projects we operated, management wouldn't approve of a managed Kubernetes solution. There are also solutions like Heroku. However, as a company where containers are our standard unit of deployment, and tries to avoid platforms that try to lock customers in, Heroku and its likes were also off the table. Platforms like Render are definitely an option. But while there are many lovers of Render and similar products, we just did not like the experience. We are of the opinion that Render was doing too many things. We just wanted to deploy containers. We were not looking for a platform offering 101 ways to deploy, but instead, we wanted 1 standard and open way to deploy. In short, Render felt like trading one pain for another discomfort. The solution we eventually settled for was to come up with a crude internal solution. After taking off a few months from product development entirely, with a couple of bash scripts, python scripts, and custom-built binaries, we were finally able to fortify our infrastructure, which held up for a while. Even though we (temporarily) solved the problem, it got me thinking a lot. I came to the obvious realization that infrastructure isn't as perfect as we sometimes assume. There are still gaps in the infrastructure space and we just saw one of them. As someone who had been looking out for a problem to found a startup around, I soon began working on what would become DOrch today. On Jan 8, I launched DOrch. While the Pro & Enterprise models are our destination, the basic model which is now out ( https://bit.ly/3Wr6VoZ ) for Engineers, Indie Hackers, and Startups, offers a peak into what the Pro & Enterprise models could offer. We are currently building on the back of AWS. Our long term goal also includes operating our own data centers ourselves. We hope we get there. https://bit.ly/3Wr6VoZ January 18, 2025 at 10:35AM

Show HN: Simplex: Automate browser workflows using code and natural language https://bit.ly/3WnpASz

Show HN: Simplex: Automate browser workflows using code and natural language Simplex is an SDK that provides low-level functions you can use to create reliable web automations using code and natural language. Here's a quick video to show you how it works: https://bit.ly/40dfXal A couple weeks ago, we needed a way to automatically find 3D assets from the internet for one of our work contracts. We didn’t need an AI to choose all the steps for us autonomously — we knew generally what the flow to find items should be and just needed some intelligence to handle different webpage formats. Playwright couldn’t easily generalize to the different sites we wanted to search over and Claude computer use was tough to use — it was slow, expensive, struggled to click on the correct web elements, and there was no way to correct its actions if it failed at step 20 of our workflow. So we built a vision-based solution using vision language models that sits on top of Playwright. In our SDK, building a function that can universally search websites is as easy as this: from simplex import Simplex simplex = Simplex(api_key="api_key") def search(website, search_query): simplex.goto(website) simplex.click("the search bar") simplex.type(search_query) simplex.press_enter() search("mit.edu", "alyssa p hacker") You can play around with what we’ve built and see a few more examples at https://bit.ly/3WlkS7P . We'd love feedback! https://bit.ly/4j9LtPb January 14, 2025 at 10:30PM

Show HN: JUring – Java bindings for io_uring file I/O Hi HN! For the past few weeks, I've been working on bringing io_uring to Java. It started as an experiment, but slowly it became more than just that, and now trying to turn it into a proper library. After hearing talks about virtual threads and io_urings performance I wanted to build something that was faster than Java provides out of the box. I ended up creating two APIs: - A direct one that closely mirrors io_uring's behavior - A blocking one built with Virtual Threads in mind for remote files. This is the link to the project if you are interested https://bit.ly/3WiBf57 It's still far from done, but it's running! Would love to hear your thoughts if you've worked on or used something similar.

Show HN: Doom (1993) in a PDF https://bit.ly/4jeo1jO

Show HN: Doom (1993) in a PDF I made a Doom source port that runs within a PDF file. I was inspired by the recent HN post about Tetris in a PDF ( https://bit.ly/3C5N8V9 ) and I wondered if I could get Doom to run using a similar method. It turns out that old versions of Emscripten can compile C to asm.js code that will happily run inside the limited JS runtime of the PDF engine. I used the doomgeneric ( https://bit.ly/42u9iLN ) fork of the original Doom source, as that made writing the IO fairly easy. All I had to do was implement a framebuffer and keyboard inputs. Unlike previous interactive PDF demos, the output for DoomPDF is achieved by creating a text field for each row of pixels in the screen, then setting their contents to various ASCII characters. This gives me a 6 color monochrome display, that can be updated reasonably quickly (80ms per frame). The source code is available at: https://bit.ly/3WhAol4 Note that this PDF can only run in Chromium-based browsers that use the PDFium engine. https://bit.ly/4h9z4sE January 13, 2025 at 01:50AM

Show HN: Bin - AI business intelligence analyst that turns data into dashboards https://bit.ly/4abrTOd

Show HN: Bin - AI business intelligence analyst that turns data into dashboards Bin is an AI business intelligence analyst that turns data into dashboards. Our goal is to make creating dashboards simpler to do than no-code alternatives like PowerBI and Tableau while preserving the powerful customization abilities of raw SQL and Python. Here’s a quick demo: https://www.youtube.com/watch?v=Fsh8M3hIjDA . Customers from our previous product wanted custom dashboards but didn’t want to spend on technical staff to build them. They wanted customizability of the dashboard yet simplicity of the building experience. So, we studied the approaches of Devin, Claude Artifacts, and v0 and wanted a version that was purpose built for making dashboards and admin pages to solve this problem. This way anyone could spin up highly custom dashboards fast without knowing PowerBI, Tableau, Python, or SQL. The interface is similar to Cursor, where you attach database context and then prompt Bin on a side chat to make visual components (charts, cards, graphs). You can then click to add these components onto your panel. On the backend, Bin spins up the components in React code and data queries in Python + SQL code in one go. We’ve wired up Bin with tool calls so that it can make the query given the schema and table context of your selected database, execute the query, and then make the component with the query key passed into our useQuery function. We make all of this code for the component and query viewable and editable on the platform. Once components are added, you can then drag and drop, resize, and reorganize them on the panel layout. The dashboard will self-update over time as more data enters your database (the queries are re-executed with every refresh). After finalizing, you can deploy the dashboard or embed it onto your other internal tools. You can try Bin today on a test database for free at https://bit.ly/4aeli5z . Please do let us know what you think – we’re open to feedback and suggestions as we continue to improve Bin. https://bit.ly/4aeli5z January 6, 2025 at 05:50PM

Show HN: Stagehand – an open source browser automation framework powered by AI https://bit.ly/4fOJpsW

Show HN: Stagehand – an open source browser automation framework powered by AI Hi HN! I’m Anirudh — longtime lurker, first time poster, and I couldn’t be more excited to show you Stagehand. Stagehand is a TypeScript project that extends Playwright with three simple AI methods — act, extract, and observe. We’d love for you to try it out using the command below: npx create-browser-app --example quickstart Here’s a sample workflow: const stagehand = new Stagehand(); await stagehand.init(); // Stagehand overrides the Playwright Page and Context classes const { page, context } = stagehand await page.goto("instadash.com") // Regular Playwright // Take action on the page await page.act({ action: "click on taqueria cazadores" }) // Extract relevant data from the page const { price } = await page.extract({ instruction: "extract the price of the super burrito", schema: z.object({ price: z.number() }) }) We built Stagehand because we loved building browser automations using Playwright and Selenium, but we grew frustrated at how cumbersome it is to just get started and write simple browser automations. These frameworks, while incredibly powerful, are built for QA testing and are thus notoriously prone to fail if there are minor changes in the UI or underlying DOM structure. The goal of Stagehand is twofold: 1. Make browser automations easier to write 2. Make browser automations more resilient to DOM changes. We were super energized by what we’ve been seeing with vision-based computer use agents. We think with a browser, you can provide even richer data by leveraging the information in the DOM + a11y tree in addition to what’s rendered on the page. However, we didn’t want to go so far as to build an agent, since we wanted fine-grained control over each step that an agent can take. Therefore, the happy medium we built was to extend the existing powerful functionalities of Playwright with simple and extensible AI APIs that return the decision-making power back to the developer at each step. Check out our docs: https://bit.ly/4gLU2xY We’d love for you to join and give us feedback on Slack as well: https://bit.ly/4fW4DVD https://bit.ly/4hqoPjZ January 8, 2025 at 05:41PM

Show HN: I built an offline open-source RAG system DataBridge https://bit.ly/4gIC2Vc

Show HN: I built an offline open-source RAG system DataBridge Hey HN! Over the past few weeks, I’ve been working on DataBridge, an open-source solution for data ingestion and querying across text, PDFs, images, and videos. In our latest update, we’ve added a fully local deployment option: - No internet required – Runs entirely offline. - Customizable Models – Supports any LLM and embedding model via Ollama (with options for any other private providers) - Extensibility – You can plug in your own models or tools easily. This local-first approach ensures better privacy, security, and flexibility, especially for teams dealing with sensitive data. You can check it out here: Docs: https://bit.ly/4j2RMnv Code: https://bit.ly/4fy0eZ2 If you can try it out, would really really appreciate it :)). Any and every feedback welcome. https://bit.ly/4fy0eZ2 January 6, 2025 at 07:53PM

Show HN: Filter out engagement bait & politics on your X/Twitter feed. hi friends! i'm pretty tired of engagement bait and all the political nonsense on my x/twitter feed. i was curious if i could use an llm to filter out these type of content, so i prototyped a quick chrome extension. it uses LLama 3.3 to analyze the tweet through https://bit.ly/3BLH7Np (because they are super-super fast). the extension is available in the chrome store, also there is a link to the repo. - you can tweak the system prompt for the filtering - but you need your own API key from Groq (you can get one for free) https://bit.ly/4gGeVe1 January 6, 2025 at 10:49AM

Show HN: E-Paper Life Organizer with Pico and Inky Frame https://bit.ly/3WaM1KD

Show HN: E-Paper Life Organizer with Pico and Inky Frame I made a desktop e paper display to show my calendar and to-do list to help keep me organized in college. Full source code available here: https://bit.ly/4gHeRuq The display is only awoken from deep sleep mode every 30 minutes to update the information, allowing the frame to be fully battery powered. You can link your Todoist for the to-do items on the left, and you can link any calendar in iCal format (Google Calendar, Outlook, etc.) for the calendar on the right. The code can be fully customized to display just the calendar, just the to-do list, or a mix of both. Let me know if you have any ideas for what features I should add next! https://bit.ly/4gHeRuq January 6, 2025 at 04:40AM

Show HN: LogLayer – Unified logger that routes logs to various logging libraries https://bit.ly/421mozO

Show HN: LogLayer – Unified logger that routes logs to various logging libraries As a longtime TypeScript/Node.js developer, I've often faced challenges with logging—choosing, using, and maintaining the right logger for various projects. While most loggers offer the usual methods like "info", "warn", and "error", they vary significantly in how they handle structured metadata or Error objects. This can lead to ad-hoc solutions, like serializing errors or writing custom pipelines, just to get logs formatted correctly. I built LogLayer to address these pain points by introducing a fluid, expressive API. With methods like "withMetadata" and "withError", LogLayer separates object injection from the log message itself, making your logging code both cleaner and more maintainable. Logs are processed through a LogLayer Transport, which acts as an adapter for your preferred logging library. This design offers several key advantages: - Multi-Transport Support: Send logs to multiple destinations (e.g., DataDog and New Relic) simultaneously. I've personally used this feature to ship logs directly to DataDog without relying on their APM package or sidecars. - Easy Logger Swapping: If you’ve ever used Pino with Next.js, you might have encountered issues where it doesn’t work out of the box after a production build without webpack hacks. With LogLayer, you can swap in a better-suited library without touching your logging code. I spent a good few months on and off and used my winter break to launch version 5 of LogLayer, and also created the documentation using Vitepress. LogLayer has been battle-tested in production at Airtop ( https://bit.ly/3BN9I4W ), where it’s been an integral part of our systems for years (we were running as Switchboard for almost four years and pivoted late last year). (Disclaimer: I work at Airtop, but LogLayer is not sponsored / affiliated with them.) https://bit.ly/421HLAV January 6, 2025 at 01:52AM

Show HN: I created a PoC for live descriptions of the surroundings for the blind https://bit.ly/4a7fVVL

Show HN: I created a PoC for live descriptions of the surroundings for the blind The difference in cost between products that are developed as accessibility tools compared to consumer products is huge. One example is camera glasses where the accessibility product costs ~$3000 (Envision Glasses), and the consumer product costs ~$300 (Ray-Ban Meta). In this case the Ray-Ban Meta is getting accessibility features. The functionality is promising according to reviews, but requires the user to say "Hey meta what am I looking at" every time a scene is to be described. The battery life seem underwhelming as well. It would be nice to have an cheap and open source alternative to the currently available products, where the user gets fed information rather than continuously requesting it. This is where I got interested to see if I could create a solution using an ESP32 WiFi camera, and learn some arduino development in the process. I managed to create a solution where the camera connects to the phone "personal hotspot", and publishes an image every 7 seconds to an online server, which then uses the gpt-4o-mini model to describe the image and update a web page, that is read back to the user using voice synthesis. The latency for this is less than 2 seconds, and is generally faster. I am happy with the result and learnt a lot, but I think I will pause this project for now. At least until some shiny new tech emerges (cheaper open source camera glasses). https://bit.ly/40lbbsE January 4, 2025 at 11:41AM

Show HN: I completed shipping my desktop app Hi, I'm a developer and first time i shipped the real product after observing the startups and indie hackers community for years. I had made so many useless apps [you should check my website https://bit.ly/4gWELdg ], but this time I built a very useful product that has a number of super easy-to-use tools in one app for video, music, and photo files. Users can compress, convert, resize, and do so much more with easy-to-use tools. Background: I developed a frame-by-frame video cropper to upload cropped landscape videos to Instagram Reels. However, it required FFmpeg, and as a noob video editor, I decided to incorporate more user-friendly video tools. I then introduced image and audio tools to maximize the capabilities of FFmpeg. I use my app daily, and it has surprisingly generated a few thousand dollars for me. https://bit.ly/4gWELKi January 3, 2025 at 01:20PM

Show HN: AI that generates 3blue1brown-style explainer videos https://bit.ly/4fRX02Q

Show HN: AI that generates 3blue1brown-style explainer videos I've been building prototypes of new AI learning tools for months, but I recently learned that 3blue1brown open sourced his incredible math animation library, Manim, and that LLMs could generate code for it without any fine-tuning. So I made a tool that automatically generates animated math/science explanations in the style of 3blue1brown using Manim from any text prompt. Try it yourself at https://bit.ly/40l0p5F (no signup required) The UX is pretty simple right now, you just write a text prompt and then start watching the video as it's generated. Once it's done generating you can download it. I built this because I kept finding myself spending 30+ minutes in AI chats trying to understand very specific concepts that would have clicked instantly if there were a visual explanations on YouTube. Technical Implementation: - LLM + prompt to use Manim well, right now this uses Gemini with grounding to ensure some level of factuality, but it works equally well with Claude - Manim for animation generation - OpenAI TTS for the voiceovers - Fly.io for hosting the web app - Modal.com for fast serverless GPUs to render the videos - HLS protocol for streaming the videos as they are rendered Note: This is focused on STEM education and visualization, and it is particularly good for math, but get creative and try it with anything! I used it recently to teach my partner's parents a new board game in Mandarin (which I don't speak!) I'll be around to answer questions. Happy learning! https://bit.ly/40l0p5F January 3, 2025 at 11:44PM

Show HN: MailMock – Simplified Email Testing for Developers https://bit.ly/40gwMSM

Show HN: MailMock – Simplified Email Testing for Developers I work at a software consulting company where we often face the challenge of testing email functionality in non-production environments. Typically, email sending is disabled in development and staging, making it difficult to verify whether emails are formatted correctly or even sent at all without making significant code changes. I experimented with self-hosting an SMTP server, but the maintenance overhead was too high. This led to the idea for MailMock, which offers a simpler solution: by simply changing the SMTP credentials, you can redirect emails without the need for server management or code rewrites. MailMock is a tool designed for developers to test emails in development and staging environments. It captures emails into dedicated test inboxes, allowing you to validate your app's or website's email flow. Features include multi-user collaboration and an email retention policy of up to 90 days, making debugging and testing easier. On the technical side, MailMock is built using C# for the backend, React for the frontend, and SQLite as the database. You can try MailMock by signing up [here]( https://bit.ly/40huIdm ). Once you sign up, you can create a project and immediately start testing by changing your SMTP settings to point to our service. Let me know what you think, or if you have any issues or suggestions! https://bit.ly/40gGEvN January 2, 2025 at 03:49AM

Show HN: I built a green noise player to help you relax, focus, and stay calm https://bit.ly/40eTkU5

Show HN: I built a green noise player to help you relax, focus, and stay calm Sometimes, I struggle to block distractions and create a calming environment while working. Most tools I’ve tried were either cluttered, didn’t provide the right kind of sound, or required payment. So, I decided to build my own simple green noise player. For context, green noise features balanced, mid-range frequencies that mimic soothing natural sounds—ideal for relaxation, focus, or creating a peaceful backdrop while working. It’s also great for taking a mindful break during a busy day. Right now, it’s a free, lightweight, browser-based solution. Playback pauses on mobile when the screen locks, but I’m exploring ways to improve it. Maybe a dedicated mobile version in the future? Would love to hear your thoughts and feedback! https://bit.ly/40gwrzt January 1, 2025 at 11:19PM

Show HN: API Parrot – Automatically Reverse Engineer HTTP APIs https://bit.ly/40ffLbA

Show HN: API Parrot – Automatically Reverse Engineer HTTP APIs When automating business processes at work, I found it difficult and time-consuming to reverse engineer business systems' APIs. I often had to manually reverse engineer APIs using developer tools or settle for less optimal technologies such as Robotic Process Automation (RPA). Often, the issue is that it can be hard to resolve all the cookies, access tokens, and other elements required to successfully execute the requests. Manually trying to resolve these dependencies using developer tools is especially challenging with multiple requests where data is stored in JavaScript objects or HTML elements. To try to solve this issue, I built a tool called API Parrot that automatically identifies the data correlations between requests and builds a graphical representation of the flow to give users a better understanding. To streamline the process, I also included functionality to record requests, define your own inputs and outputs, and export the entire flow—or parts of it—as JavaScript code. The application is Electron-based and currently compiled for Windows and Linux. Please try it out and give feedback!
