What is Multiplayer?
Open-source agent that spots production errors and hands coding agents the session data to fix them.
Who is Multiplayer best for?
Multiplayer is best for engineering teams using Claude Code who want production bugs triaged and turned into fix PRs.
Fixing production bugs with Claude Code
When an error or exception shows up anywhere in the stack, it sends the session data to your coding agent and opens a PR with the fix.
Cutting duplicate fix PRs
Issues are grouped so the same bug is tracked and fixed once, however many times it happens.
Data that must stay in-house
Self-hosted, session data never leaves your infrastructure, and it sends data on only when a new issue appears.
Full-stack session replay
SDKs for JavaScript, React Native, Go, .NET, Python, Ruby and Java record screens, traces, logs and request and response content.
How much does Multiplayer cost?
Multiplayer is free and open source under the MIT licence; its hosted plan is closing, so new users run it on their own infrastructure.
- Whole platform under MIT: web app, services, SDKs
- Runs with Docker Compose
- Claude Code support; Codex and Copilot in beta
Multiplayer's team joined FilingRamp and is closing the hosted plan: people already on its 7-day trial can finish it, then move to the self-hosted version, which the team says it will keep supporting. Enterprise features such as audit logs and compliance reports are licensed separately. Full pricing on multiplayer.app. We checked these prices on .

How do I connect Multiplayer to my AI agent?
Multiplayer MCP is Multiplayer's official MCP server. Add it to your agent once, then ask it to feed real user sessions, traces and logs to your coding agent.
Your agent can pull a recorded session from your app, with what the user saw and clicked tied to the backend traces, metrics and logs, so it can follow a bug end to end.
Multiplayer gives each account its own server address. Open the setup guide, copy your address, then add it to Claude Code like any other server.
Use the address from Multiplayer's setup guide.
Multiplayer's setup guide covers the sign-in.
Then ask your agent
