Durable Objects
Durable Objects are stateful serverless primitives provided by Cloudflare that provide strongly consistent state storage coupled with compute, designed to solve problems like session management, collaborative editing, and real-time multiplayer coordination.
Durable Objects allow developers to store state in a way that is persistent and consistently accessible by compute logic. By binding a unique identifier to a single instance of a class, Durable Objects ensure that all requests to that object are processed in a specific, ordered manner, eliminating the race conditions common in distributed systems. This makes them ideal for building MCP-like gateways or multi-agent orchestrators where session state must be maintained across disparate requests.
