SimonAKing(@simon_aking):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 🙏 @lawrencecchen built cmux → @mosaic_ide built mosaic on top of it → and here we are. 👇
