Show HN: Replicant Space – an HTTP API-based game based on the Bobiverse books https://bit.ly/3RCnZcy

Show HN: Replicant Space – an HTTP API-based game based on the Bobiverse books During Christmas 2025, I found myself burnt out from work. The last few years had been hard, and multiple redundancies saw the company I loved reduce down to just a handful of remaining staff. As a coping mechanism, I kinda disassociated for a while - throwing myself into my personal projects. AI was destroying the passion I had for coding. I tried to find some meaning in development again. After months of throwing myself into creating this game, I slowly fell back in love with coding. I taught myself a bunch of technologies that I was previously unfamiliar - Astro, Flask, Redis, Celery, Just. Anyway, this is Replicant Space. It's free. I love building and playing it. There's a cool story. Aliens are awesome. Feel free to poke the API and take over the galaxy. https://bit.ly/4h5m7n0 July 29, 2026 at 10:57PM

Show HN: GG Translator – Turn gaming shit talk into friendly phrases https://bit.ly/45abJDn

Show HN: GG Translator – Turn gaming shit talk into friendly phrases Flaming teammates usually results in them cooperating even less. But sometimes you just need to let the devil out of you. Instead of venting on your teammates and pissing them off, vent into GG Translator and it will convert your toxic message into a friendly and constructive one to share with your team. https://bit.ly/4wsxdqW My background is in building web apps with Elixir and Phoenix. I made GG Translator in early 2024 to see if I could build a desktop app in a language I had never used before (Rust) with the help of AI. It was a great exercise and I found out that I could. I used Tauri instead of Electron because it has a smaller footprint. I built the app but never released it because I wasn't ready to support it. When GPT 5.6 came out earlier this month I pointed it at the old codebase and tasked it with rewriting that entire app (still in Rust using Tauri), modernizing, refactoring, and looking for any improvements that it could find. --- The app is a sneak peek of how an AI profanity filter might look like in the future. The ultimate integration would see it built into gaming platforms like Steam and PSN where it's not only transforming your speech on demand, but it's also able to transform incoming audio from your teammates into family friendly language so parents can feel better knowing their kids aren't being bombarded with slurs when they let them play online multiplayer games. I also imagine an incredible opportunity for voice licensing allowing users to pay to unlock voices of their favorite streamers, actors, athletes, and characters for a limited time. Who wouldn't want to sound like Samuel L. Jackson yelling about motherfucking noobs in their motherfucking lane? --- The biggest obstacle was code signing. I went through all the hurdles in 2024, paying for an expensive OV signing certificate and also paying for the Apple Developer program. For 2026 I decided that the OV signing certificate is a racket and I'm not going to pay for it again. I already have an Apple Developer account for another app so I didn't have to pay extra to sign the macOS build. For Windows, the SmartScreen warnings when installing the app are a drag, but you can just tap more info and install it anyway. https://bit.ly/4wsxdqW July 26, 2026 at 11:23PM

Show HN: SpinWin – A macOS menu bar app to visually rotate or spin any window https://bit.ly/4woTPIY

Show HN: SpinWin – A macOS menu bar app to visually rotate or spin any window SpinWin is an open source menu bar app to visually rotate any individual window. You can rotate / spin as many as you want one by one. I was scrolling reels when one came on where the content creator suggested "turning the phone upside down" for a portion. I was sitting at my mac, and decided to see if I could find something that did this. To my surprise, nothing exists, so I decided to build it. Turns out macOS doesn't provide any public API to do anything like this, so I wound up using the Accessibility API to move the target window offscreen, where it keeps rendering. Then we capture it's contents with ScreenCaptureKit, and display that on a transparent, borderless overlay window which has a CALayer to rotate it. It's written in Swift, open source, MIT license, and signed/notarized. Have fun - would love to hear your comments. https://bit.ly/4wjgGFH July 25, 2026 at 06:29PM

Show HN: Life Tile – Passive time tracker that shows your day as a Mondrian grid https://bit.ly/4fywEVa

Show HN: Life Tile – Passive time tracker that shows your day as a Mondrian grid Hi, I developed Life Tile for iPhone. It tracks your time passively and visualizes it as a Mondrian-style grid. It's a one-time purchase app with a 7-day trial. I was a user of a similar app named Life Cycle. Since the app hasn't been updated in a while, I tried to make a better app with my ideas and experiences. I used a big square timeline instead of a donut chart. And I added more useful views: tree-map, map, and list. You can use categorized activities with custom colors. The data never leaves a device. No account, No Server. It only supports data backup using iCloud. It was for privacy but it also makes the development easier. I added just one anonymous usage stat with TelemetryDeck. You can turn it off anytime. There were many technical difficulties. iOS location API (CLMonitor) is not 100% precise. And many difficult cases can't be handled automatically. For example, GPS blackout inside the subway, too many venues in a small region, and a huge location like an airport. So I improved many heuristics and tried my best for easy editing. Please check the App Store for the screenshots. Then you'll know why it's inspired by Mondrian. https://apple.co/44LtV60 July 24, 2026 at 01:13AM

Show HN: Connecting my dumb garage and car's homelink buttons to Home Assistant Hi all, I've been on parental leave and while working on my garage door, I thought to myself... it would be great to open up this garage door from my phone without having to buy a bunch of expensive stuff. That snowballed into, I want the garage door buttons on my car's rear view mirror to trigger automations in home assistant. I went down a bit of a hardware rabbit hole and wrote a little writeup of my journey and a how-to. It's my first piece of public technical writing so I'm open to any feedback! https://bit.ly/3RnDzbT July 23, 2026 at 10:28PM

Show HN: LitigationBench. A Litigation Task-Based AI Benchmark https://bit.ly/4wXMlMD

Show HN: LitigationBench. A Litigation Task-Based AI Benchmark Adding to the sea of AI benchmarks, but with a focus on legal and litigation-based tasks and tests. E.g., hallucinating cases, misreading precedent, drafting, AI writing tics, etc. Developed as part of a litigation platform I've started, but not sharing this benchmark to promote that. Just thought the findings were interesting--namely, Anthropic's models (except for Haiku) producing zero hallucinated cases. Also, if anyone would like to see additional tests / benchmarks or models tested, let me know and I'll incorporate them into v3 if it makes sense. https://bit.ly/44LOkb3 July 23, 2026 at 02:11AM

Show HN: An MCP server that turns async-work practices into tools https://bit.ly/4gRAJpR

Show HN: An MCP server that turns async-work practices into tools More than a decade ago, I adopted the self-imposed rule, if I answer a question more than once, the third time I need to be able to answer with a URL. Today, I published one very large URL - a book distilling what I learned from helping people work remotely at GitHub, and I wanted to rethink my rule for the age of AI. What if, instead of a URL, I could create an interactive experience that could tailor the guidance to your particular situation? What I ended up building was an Open and Async Advisor MCP server. To install (in claude or any other AI): > claude mcp add open-async -- npx -y @open-and-async/mcp Transparently, yes, it's from a book I wrote which launched today, but the MCP server is open source and free to use. No purchase required. It knows the key principles of the book, and has specialized tools like `draft_decision_doc`, `convert_meeting_to_async`, `score_status_update`, `triage_sync_vs_async`. This is an experiment for me, and I'm genuinely curious if it's helpful for others. https://bit.ly/4b9bk7w July 21, 2026 at 05:06PM

Show HN: Superserve – Firecracker microVM sandboxes for long-running AI agents https://bit.ly/4wz3TPL

Show HN: Superserve – Firecracker microVM sandboxes for long-running AI agents Hey HN, I built Superserve, a compute layer that lets AI agents live inside isolated Firecracker microVMs with no session time limits. The problem I kept running into: most sandbox providers kill your agent after 24 hours. If you're running something autonomous that needs to work for days — refactoring a codebase, running tests in a loop — you're constantly fighting timeouts and rebuilding state. Superserve lets you snapshot a running VM at any point, fork it into parallel branches, and resume exactly where you left off. Each agent gets its own VM, no shared kernels. There's also a credentials broker so agents never touch raw API keys directly, and egress is locked to URLs you specify. You bring your own agent (Claude Code, Codex, etc.). We handle the durable compute underneath. TypeScript and Python SDKs, MCP support, open-source and self-hostable. Would love to hear feedback, especially from anyone building long-running agents. https://bit.ly/4vL0RXh July 21, 2026 at 11:59PM

Show HN: Ekko – post-quantum E2EE layer for Instagram, WhatsApp, Telegram Web https://bit.ly/4gJYoZi

Show HN: Ekko – post-quantum E2EE layer for Instagram, WhatsApp, Telegram Web Hi everyone, I am a big privacy activist and the amount of privacy concerns in the internet with the discussions around European Chat Control, Meta removing e2ee in Instagram and corporations harvesting personal data for AI training is on the rise. The closed source social media companies keep managing and storing our private keys, allowing them to effectively access all of our personal communications.. Many open source alternatives exist, but the problem I kept running into was not a lack of good private messengers. Signal, SimpleX, and other projects already do important work The problem was getting the people to move. A messenger is only useful when the person you need to reach is there. Asking friends, family, coworkers, or customers to abandon their existing chats is a very high barrier. Ekko takes a different approach. It runs as a browser extension on top of existing messengers. Both people still need Ekko, but they do not need to move their conversation. You can continue using the Instagram, WhatsApp, Telegram, or Messenger chat they already share. Actively building this and trying to achieve a seamless automatic encryption in the UI across all popular messengers and adding support across all browsers, IOS, android and social media.. Under the hood, Ekko uses hybrid X25519 + ML-KEM-768 and XChaCha20-Poly1305. Private keys are generated and kept on your device. You can claim an Ekko handle to make exchanging public keys easier, exchange invitations directly without an account, or self-host the public-key directory. Currently: - A Chromium browser extension, Experimental Firefox and Safari builds - Instagram, WhatsApp Web, Telegram Web, and Messenger integrations - A self-hostable key directory - Open-source client, protocol, and server code Early version Chrome Web Store: https://bit.ly/4fN1z1e... Source code: https://bit.ly/4fLTTMN Website and demo: https://bit.ly/4h7nqlt I would genuinely appreciate direct feedback especially from people familiar with applied cryptography, browser security, key verification, messenger integrations, potential solutions for iOS UI integration (faster than using browser w/ Safari extension) If you try it, please tell me what breaks or what feels confusing. Actively trying to make this better as a side project! If you discover a security issue, email kirill@useekko.app rather than posting it publicly. Looking for feedback! :) https://bit.ly/4h7nqlt July 21, 2026 at 01:39AM
