I just open-sourced AgentOS, a tool I built for myself when I got tired of juggling a bunch of terminal windows while working with Claude Code. You can run it yourself and it's completely free.
It's a web UI that lets you:
- Run multiple Claude sessions side-by-side (up to 4 panes) and each pane can have multiple tabs for those power users out there - Fork conversations when you want to try different approaches - Organize sessions into folders - Have an embedded terminal right there - Sessions persist via tmux so you can close your browser and come back
Stack is Next.js 16 + React 19, SQLite for local persistence, xterm.js for the terminal.

Would love to hear any feedback or feature ideas. I'm still planning on adding more to it!
