Show HN: Toolbrew – Free little tools without signups or ads
I got tired of fighting through spammy tool sites just to do something simple, so I made Toolbrew in a few hours on Replit. Just a bunch of free little tools in one place. Text converters, SEO checks, video downloaders, that kind of stuff. No signups, no ads.<p>If there is a tool you wish existed, you can request it on the site and I will build it. Do your worst. Seriously, ANY tool.<p>Maybe it helps, maybe not. Enjoy!

Show HN: Lingo – A linguistic database in Rust with nanosecond-level performance
Hi HN, I made Lingo - the SQLite of semantic search.<p>I'm a self-taught developer and researcher who left school at 16, and I've spent some time exploring a first-principles approach to system design for various frontier problems. In this case it's AI that challenges the 'bigger is better' transformer paradigm.<p>Lingo is the first piece of that research, a high-performance linguistic database designed to run on-device.<p>The full technical overview and manifesto is here: <a href="https://medium.com/@robm.antunes/bcd1e9752af6" rel="nofollow">https://medium.com/@robm.antunes/bcd1e9752af6</a><p>The paper has been archived on Zenodo with a DOI: <a href="https://doi.org/10.5281/zenodo.17196613" rel="nofollow">https://doi.org/10.5281/zenodo.17196613</a><p>The code is open-source and can be found at <a href="https://github.com/RobAntunes/lingodb" rel="nofollow">https://github.com/RobAntunes/lingodb</a>, it's currently broken and feature incomplete but I'm working on it - just wanted to start getting some feedback.<p>All benchmarks are reproducible from the repo and can also be found in the various texts.<p>As an independent without academic affiliation, I'd be incredibly grateful for your feedback!
I'm here to answer any questions.<p>Cheers!
Show HN: Family Chess: Play across firewalls and Internet cultures
Hi HN! I built a simple chess game so that my son in Singapore can play chess with his grandfather in China.<p>Why? There is currently no service or open source software that has all of the following:<p>* All processing and assets on a single server (Critical to workaround a firewall)
* No email account required (Chinese Internet services typically login via WeChat)
* Works on Android browser
* Simple to install and config<p>I built it, together with Claude Code, using simple and boring technologies (Django + Client-side JS). I hope that when you use it, you will find it simple to understand (everything is done server-side), deploy, play, and maybe even hack. :)<p>Live demo: <a href="https://family-chess.quee.org" rel="nofollow">https://family-chess.quee.org</a> (Please be gentle, it's a tiny 2GB VPS!)

Show HN: An open source Launchpad for macOS 26
An open sourced version of Launchpad that I enhanced, you can import from old system Launchpad (just one click), and most of things look same. There are also a lot of functions, like adjust / display / hide icon size and title, localize icons, game controller support, i18n, voice over, etc.<p>Still updating, open an issue if there are any problems. Hope this could help if someone updated to MacOS26 and not happy with new Launchpad :)<p>Thank you.
