hey hn, i built matrix os, a personal ai operating system that generates custom software from natural language.

you get your own cloud instance at matrix-os.com. you describe what you want ("build me an expense tracker with categories") and it appears on your desktop as a real app saved as a file.

tech stack: node.js, typescript, claude agent sdk as the kernel, next.js frontend, hono gateway, sqlite/drizzle. everything is a file, apps, data, settings, ai memory. git-versioned.

what makes it different from chatgpt/claude artifacts: - persistent memory that learns your preferences across sessions - apps are real files you own, not ephemeral chat outputs - runs 24/7 in the cloud, not just when you have a tab open - accessible from web, telegram, whatsapp, discord, slack - open source, self-hostable

came out of placing top 20 at anthropic's claude code hackathon. been building it full-time since.

2,800+ tests, 100k+ lines of typescript

live: matrix-os.com github: github.com/HamedMP/matrix-os

would love feedback on the approach. the core bet is that ai should be an os, not a chat window.

Cool :)
