New features
Multiplayer MCP server
With the Multiplayer MCP (Model Context Protocol), you can feed your copilots and AI IDEs the complete system context they need: user actions, traces, logs, requests, responses, header data, plus user annotations.
No missing data, no guesswork. Your AI tools can generate accurate fixes, tests, and features with minimal prompting.
Choose your preferred language and follow the setup guide:

Free sandbox to explore full stack session recordings
We’ve launched a brand-new sandbox environment so you can explore Multiplayer without signing up for a free trial (or having to provide your email or other personal details!).
This isn’t just a static demo project: we built a fully functioning application to power it.
In the app, you can chat with fictional and historical characters, trigger bugs (yes, we planted a few 😉), and see how every interaction is captured as a full stack session recording.
When you land in the sandbox, you’ll find:
- Pre-populated full-stack session recordings with correlated frontend screens, backend traces, logs, and request/response data, etc.
- The system dashboard, with auto-discovered services and dependencies
- Example notebooks, where you can interactively develop, test, debug, and document API integrations
You can also create new recordings instantly by clicking “Record a session yourself” and having a chat with your favorite historical / fictional character.
Some features are read-only for safety, but the sandbox behaves like a real Multiplayer project, so you can experience what Multiplayer actually feels like in practice before you sign up for your free trial: go.multiplayer.app
