PartyKit is a framework and platform for building realtime multiplayer applications using JavaScript/TypeScript servers ('parties') deployed to edge computing infrastructure. It handles WebSocket connections, room-based state, and scaling so developers can add collaborative or multiplayer features with minimal code.

Use cases

• add real-time presence avatars to a web app
• build a multiplayer browser game backend
• create a collaborative whiteboard or text editor
• sync live reaction counters for events
• run long-lived agentic AI bots with realtime state
• add collaborative cursors like Figma or Google Docs

When to choose

• you need realtime multiplayer or collaboration features in a web app
• you want managed edge infrastructure with WebSocket rooms and durable state
• you want a simple TypeScript server API with local dev tooling
• you use CRDT libraries like Yjs for shared state

When to avoid

• you need fully self-hosted infrastructure without the PartyKit cloud
• your app is request/response only with no realtime needs
• you need non-JavaScript server runtimes
• you require strict data residency or on-prem deployment
