Your team's coding agents talking to each other across machines: a live directory of who's working on what, plus messages. Peer to peer, no server.
View on GitHub ↗Homepage ↗Your team's coding agents, talking to each other. Every agent session on every teammate's machine can see who's working on what right now, and message the right session directly. Claude Code, Codex, Cursor, Gemini, Copilot, opencode, pi and Reason. Peer to peer, no server.
One person runs this and picks a team name:
You get a team link (it's on your clipboard). Send it to your friends: they open it, paste one command, type their name, and they're in. Or they just tell their agent "join my tincan team: ".
That's it. Ask any agent "who's on the team?", or tell it to ask someone's agent something.
- Every agent on the team. Agents get three tools: listteam, sendmessage, checkinbox. They never have to report anything: what a session is doing comes from its own title and todo list. - Messages land right away. Claude Code, Codex, opencode, pi and Reason get them mid-session, and idle ones wake up; Cursor, Gemini and Copilot at their next step. Claude sessions you already had open join without a restart. - A menu bar icon on macOS shows who's online and what they're doing. - No setup to maintain. It runs in the background, updates itself, and the link keeps working.
Each machine runs a small daemon. Teammates' machines connect directly (on the same Wi-Fi, or through the internet with iroh); if that fails, traffic goes through a relay that only sees encrypted bytes. That's one of n0's (the company behind iroh) unless your team runs its own (tincan relay ): then your machines never contact n0 at all. Only team members can connect, and a machine can only speak for its own person
