Claude Code multiplayer — but it runs on Your servers. 🔒
Your whole team drops into one live terminal and drives the same Claude Code / Codex session in real time — presence, approvals, the works.
The twist: it's 100% self-hosted & open source. One command deploys the entire backend to your own
@Cloudflare. Nothing ever touches a third party.
Standing on the shoulders of giants 🙏
