Plane is a distributed system for running stateful WebSocket backends at scale, acting like a distributed hashmap of running processes keyed by session. It dynamically spawns, routes to, and reaps per-session processes, inspired by Figma's multiplayer infrastructure.

Use cases

• scale authoritative multiplayer backends per document
• run isolated code environments like REPLs and LLM agent sandboxes
• spawn a dedicated high-RAM process per active user session
• route WebSocket connections to per-key backend processes
• automatically shut down idle session backends
• ensure a single authoritative process per document key

When to choose

• you need per-session or per-document stateful WebSocket backends that scale dynamically
• you want isolated ephemeral compute environments (sandboxes, REPLs, agent runtimes)
• you need a single authoritative process per key with automatic lifecycle management
• you want a Figma-style session backend architecture without building it yourself

When to avoid

• you only need stateless HTTP request handling or simple load balancing
• your workload is batch or background processing with no live connections
• you need long-running services that persist without active connections
• you want a fully managed cloud service rather than self-hosted infrastructure
