Plane is a distributed system for running stateful WebSocket backends at scale. Plane is heavily inspired by Figma’s mulitplayer infrastructure, which dynamically spawns a process for each active document.
Use cases include:
- Scaling up authoritative multiplayer backends.
- Running isolated code environments (like REPLs, code notebooks, and LLM agent sandboxes).
- Data-intensive applications that need a dedicated high-RAM process for each active user session.
