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.
