Multiplayer Claude Code

Code with Claude,
with your friends_

Poly is a shared room where your team steers one coding agent — every prompt, every diff, and every dollar visible to everyone in it.

Free to sign up. Bring your own Anthropic API key — you only pay for what you run.

One timeline, everyone steering

Prompts queue into a shared room. Every turn, tool call, and diff happens in front of the whole team.

Trust, but verify

Review prompts before they run. Approve edits and commands before they execute. Revert any turn with one click.

Everyone pays their own way

Turns run on their author's own API key and model — the receipt shows who spent what, down to the cent.
