durable-objects

Durable Objects are Cloudflare's primitive for stateful, coordinated logic at the edge. Each instance has its own SQLite storage, in-memory state, and execution context. They handle WebSockets, alarms, and RPC methods for scenarios where multiple clients need to share consistent state. Instead of running a separate stateful server or coordinating through an external database, Durable Objects let you place coordination logic at the edge, co-located with storage, without managing infrastructure.
