YAOS – A 1-click deploy, real-time sync engine for Obsidian▲5
Hey HN, I'm a heavy Obsidian user. I recently got tired of the two usual sync tradeoffs: 1. File-based sync (iCloud/Dropbox/Syncthing) that leaves you waiting for changes to propagate, or hands you a "conflicted copy." 2. Self-hosted setups (like CouchDB) that need touching VMs and dockerized databases to sync markdown. So I built YAOS: a local-first, real-time sync engine for Obsidian. Self-hosting OSS should have better UX. You can deploy the backend to your own Cloudflare account in one click. It fits comfortably in Cloudflare's free tier (costing $0/month for normal…

Katipo is a minimal alternative internet with a Vulkan based browser▲5
I’m nervous, announcing this, as it isn’t ready to ship out to the general public yet, and I haven’t had any feedback at all from anyone, I’m out on my own here. I think this concept itself is kind of dismissed outright a lot too, and I understand why, I wouldn’t believe me either actually. But, I do believe this is very much worth your time to check out, I am not aware of anything else very much like it. I won’t repeat what is already written on the github README here, but some info: I am a successful semi-retired solo game developer, I have been making my own bespoke game engines since…

I made a browser TUI with its own layout engine▲6
Try it at: ssh krnl.duetbrowser.com No sign up, totally free - no download. Let me know what you think. Prior art exists (brow.sh) but I wasn't satisfied with their graphical take. I wanted the raw, old skool terminal days of the early internet - BBS, and old green phosphor library comptuers - but running the modern web, with all the bells and jingle jangle whistles (JavaScript, etc). No funding, no VC, just 100% raw terminal fun. Not sure how long the demo will last, but try it out.
