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The paper has been archived on Zenodo with a DOI: 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.

Show HN: Signage Sync
Hi guys, I'm sharing something I've been tinkering on for a while: <a href="https://signagesync.app/" rel="nofollow">https://signagesync.app/</a><p>Like Google Chromecast, but "cast" to multiple screens at once. Create a playlist of auto-refreshing web pages, videos, and even live streams (but not supported on Windows). Also works with local network, e.g. <a href="http://192.168.../sales-dashboard" rel="nofollow">http://192.168.../sales-dashboard</a><p>It's still early (MVP), but already usable—and I'd love to hear your feedback.<p>Tech stack: SvelteKit, WebSocket, Flutter (desktop)
Show HN: Mosaic – A Kotlin framework for cleaner back end code
Backend APIs often grow into large orchestration classes full of duplicated calls and manual concurrency.<p>I’ve been working on Mosaic, a Kotlin framework that composes responses out of small, request-scoped “tiles.” Each tile runs once per request, dependencies resolve automatically, and independent tiles execute in parallel without boilerplate.<p>It’s still early (v0.2.0), but working today for caching, concurrency, and testability. Curious to hear feedback on the approach.<p>GitHub: <a href="https://github.com/Nick-Abbott/Mosaic" rel="nofollow">https://github.com/Nick-Abbott/Mosaic</a>

Show HN: Macscope – I decide to built a better Cmd-Tab replacement for macOS
Hi HN,<p>Macscope is a new window manager and and app switcher for macOS built on the philosophy of enhancing, not replacing, your existing muscle memory.<p>It works by augmenting the familiar Cmd+Tab workflow. A quick tap of your shortcut instantly switches between recent apps, just like you're used to. A slightly longer hold, however, opens the full Macscope interface where you can manage all your open windows and tabs.<p>You can also use modifier shortcuts to enter Placement Modes, which let you instantly snap a selected window to the left/right/top/bottom/ half of your screen.<p>Here are some of the key features:<p>- Unified Search & Switch: A single interface to instantly find and switch to any window, browser tab (Safari, Chrome, Arc, etc.), or application just by typing.<p>- Live Previews: See a real-time preview of what's inside each window so you know exactly where you're going. You can also disable previews for a more minimal experience.<p>- Advanced Window Management: Go beyond just switching. Select multiple windows and arrange them into layouts like vertical/horizontal splits or grids.<p>- Scopes: Save collections of app windows as a "Scope" and instantly restore that entire workspace later. It's ideal for quickly switching between different projects or tasks.<p>It’s a native macOS app built with Swift and supports both Apple Silicon and Intel machines.<p>Launch Offer for HN:<p>There's a free trial with 250 actions. For the Hacker News community, I'm offering a 50% discount on the lifetime license.<p>Website: <a href="https://macscope.app" rel="nofollow">https://macscope.app</a><p>Discord Community: <a href="https://discord.gg/ehktEWr97K" rel="nofollow">https://discord.gg/ehktEWr97K</a><p>I'll be here all day to answer questions and would be grateful for any feedback. Thanks for checking it out!
