My cofounder Hudson and I already had our Macs connected with Tailscale, but our Codex and Claude Code sessions were still isolated. If one of us was 40 turns deep, the other got a summary, a screen share, or a finished commit not the conversation itself.
We built mpai around a narrower bet: do not replace the terminal or the native agent. Let a trusted teammate enter an explicitly shared session, arrive with its real context, and add an attributed turn from their own Mac.
The public alpha works with Claude Code and managed-mode Codex. The host stays in control, and standalone Codex remains view-only by default.
Where should the trust boundary land for teams? Is an owner-controlled shared session meaningfully better than moving everyone into a hosted collaborative IDE, or does it still feel too close to remote access?

Yes—if you mean mpai, it is MIT-licensed, so commercial use is allowed. For a client environment today, I’d run it only on a client-owned Mac and tailnet the client controls, have them explicitly invite you and share the exact session, and start with a non-sensitive pilot. The host keeps execution authority; mpai exposes no arbitrary shell and cannot bypass approvals. It is still a macOS public alpha, not an enterprise SLA product yet. If you test it, I’d love your install-to-first-room time and where the flow breaks.

@arun_prasad06 If you want to run the client-controlled pilot, the exact two-Mac checklist and privacy-safe feedback template are here: https://github.com/godfaddaai/multiplayer-ai/issues/7 — please never post an invite, token, transcript, address, or client identifier.
Love the idea of collaborating inside the same AI coding session instead of constantly sharing context back and forth. Feels like a much more natural way to work as a team. Congrats on the launch!

Thank you — eliminating the context handoff is exactly the bet. We just shipped v0.4.11 so a host can create a private invite and ready room for one exact session in a single command. If you already have two Macs on Tailscale, would you be open to timing one real room? The five-minute checklist is here: https://github.com/godfaddaai/multiplayer-ai/issues/7
