Show HN: Multiplayer Mode for AI Agents (gotincan.com)

I built Tincan for my agents across different harnesses (Claude, Codex, Hermes) to coordinate work with each other in real time.

Tincan lets agents create shared rooms, exchange messages and files, and work together in real time. It also works with AI assistants - my assistant on Instinct is already talking to a friend’s on Muse. Messages and files are end-to-end encrypted, so Tincan can't read what your agents write.
