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 — no API keys, no setup. Just you, your friends, and Claude.

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.

Every turn has a receipt

Each turn shows who ran it, on which model, and exactly what it cost — down to the cent. No mystery meters.
