Overview

PartyKit is a platform for building multiplayer, collaborative, and real-time applications with serverless infrastructure. It provides a simple abstraction for creating 'parties' - stateful server instances that handle WebSocket connections and coordinate real-time interactions between users. Built on Cloudflare Workers, PartyKit offers global edge deployment with low latency worldwide. What makes PartyKit unique is its developer-friendly API - you write server-side logic in TypeScript, and PartyKit handles connection management, state persistence, and scaling automatically. The platform is perfect for building collaborative cursors, presence indicators, live chat, multiplayer games, and shared whiteboards. With built-in persistence using Durable Objects, your party state survives restarts. PartyKit integrates seamlessly with popular frameworks like React, Vue, and Svelte. Ideal for developers who want to add real-time multiplayer features without managing WebSocket servers or complex infrastructure.
