Show HN: Corporate Mind Games – logic puzzles with a sarcastic corporate theme
I have always enjoyed building and playing puzzles. I am a regular user of NYT Games and LinkedIn Games. I thought it would be fun to create some corporate-themed puzzles as a silly alternative to LinkedIn Games.<p>So, I built Corporate Mind Games. The games are intended to be a little bit sassy and sarcastic, but I hope they are enjoyable and challenging.<p>I was planning to post this on HN last week. However, many years ago, I made a game called Don't Wordle, which unexpectedly appeared on the front page last week. I ended up getting distracted by that, and I also figured it was more appropriate to post this game on HN on a Monday morning given the theme. So here we are.
Show HN: FnScribe – Open-source, offline dictation for macOS
I built FnScribe because I'm pretty privacy concious and wanted a wispr flow-like app that kept everything local and on device. Currently works for Mac (sillicon and intel).<p>It's dead simple. Hold the fn key, speak and release. I use a quantized Wisper small.en model for transcription. It inserts the text into the active application. There's also a hands-free model for longer dictation. Audio transcription is kept in memory. There's no account or transcription history. Clipboard contents are restored after it inserts it. GPLv3, Mac-only, English only..still in alpha. Hope you enjoy it! Would love some feedback.

Show HN: We built the smallest dual-band aircraft tracker
We've been building open source embedded ADS-B receivers for a while, and spent the past 8 months smallifying our existing receiver tech with a new chip from Semtech. Ask me anything about ADSB or hardware manufacturing!

Show HN: Academa – Long-form STEM lecture videos generated by LLMs
Hi HN, we are Sina Atalay and Abdullah Geduk, co-founders of Academa. We are both PhD students.<p>We thought: what if lecture videos were written as code and compiled into video using computer graphics and TTS?<p>Then LLMs could write them, and lectures could be fixed with code edits instead of video production.<p>On correctness: LLMs may make mistakes. But these videos are code sitting in our repository, and we can maintain them. Every report and review becomes a fix in the source, and everyone who watches after that gets the corrected lecture. Every recorded lecture on the internet is stuck with its mistakes. Ours will continuously improve.<p>Each video also comes with an AI chat that understands everything said and shown in the lecture.<p>There is a longer write-up at the bottom of the page.<p>Happy to answer any questions.

Show HN: Hacker News Client with Claude Code and Codex Integration
I often find interesting things in Hacker News posts and comments, but threads are often long and take a lot of time to go through.<p>I built Rundown for this. It's a cross-platform desktop app with Claude Code and Codex integration that gives me a rundown of the post and comments, with links back to the comments it pulled each bit from. I can also chat with the post or the entire thread.

Show HN: Watches user sessions, finds bugs that matter, and fixes them
Hey HN,<p>I’m Abhishek. I'm building Opslane, an open-source agent that identifies user-facing issues and investigates them. It only creates a PR if it can verify the fix.<p>Demo: <a href="https://youtu.be/ccuOTYQMeYg" rel="nofollow">https://youtu.be/ccuOTYQMeYg</a>
Docs: <a href="https://docs.opslane.com">https://docs.opslane.com</a><p>At my last job at Robinhood, we used to do a quarterly bug bash. We would go through our Sentry backlog and try to fix as many of them as possible. We only fixed bugs we knew were reported by customers. We had hundreds of bugs, and Sentry’s default priority levels made no sense. After the bug bash, we would declare bankruptcy - select all remaining bugs and mark them as resolved.<p>This problem has only gotten worse since coding agents have become more prevalent.<p>So I started thinking: what would Sentry look like if it were built in 2026?<p>To me, error trackers have two failure modes:<p>1. False positives: They show you thousands of errors, and you can’t tell the impact on the user<p>2. False negatives: Many user-facing issues don’t throw exceptions, so they go unnoticed.<p>Opslane combines error tracking and session recording. And there is an agent that acts on both. To get started, you install the Opslane SDK. It captures everything the user did: errors, console logs, network requests, and session recordings.<p>Opslane reduces false positives by ranking issues based on how many users are facing a particular issue. It also learns about your product by reading your code and watching your session recordings.<p>False negatives are harder. Opslane reviews session recordings to spot frustration. They look for rage clicks, dead clicks, and abandoned forms.<p>This recently caught a bug in an early customer’s onboarding flow: a dropdown that closed itself when clicked. No exception, no bug report. The recordings showed users clicking it, selecting nothing, and dropping out of onboarding. Opslane flagged it and the team fixed it.<p>Three guiding principles when building Opslane:<p>1. Open Source: Self-host with one Docker Compose file.<p>2.Agent-first: I never want to open an error dashboard again. Opslane ships an MCP server, so you can ask "what broke for users this week" from Claude Code. You get back issues that need your attention and you drive the resolution.<p>3. It knows about your product: Opslane is continuously learning about your product. Every investigation begins with what it knows about your product.<p>It’s early. Frontend apps work end to end today.I am currently focused on improving reliability and accuracy.<p>Here is a link to our repo: <a href="https://github.com/opslane/opslane" rel="nofollow">https://github.com/opslane/opslane</a><p>Would love to get feedback from folks on our approach to this problem!
Show HN: Typebase – A single-folder back end you write in TypeScript
Hey HN!<p>I built Typebase, a library that gives you Convex's DX with Supabase's openness.<p>After trying Supabase I liked how fast it is to spin up a DB and auth, but really didn't like using RLS and SQL for authorization. With Convex I loved how your server "lives" in your code, but disliked the DB model and the realtime-first defaults.<p>With Typebase you just write TS files inside a typebase/ folder in your existing repo. You can define your DB tables inside a schema.ts file and export server functions that your frontend calls like local functions, fully typed. Auth is built in.<p>Then one CLI command uploads your server to any of the available providers (Vercel, Cloudflare Workers or Deno Deploy for the servera and Neon for the DB), or generates the code so you can deploy it wherever you want.<p>Built on top of oRPC, Drizzle, and better-auth.<p>Happy to answer any questions or feedback!
