Durable Objects Explained

Serverless functions, like Cloudflare Workers, are typically stateless. This means each request is processed independently, without remembering past interactions.

While great for scalability and cost-efficiency, what if you need to maintain a consistent piece of information across multiple requests or users globally? Think about a live chat room, a game lobby, or a shared counter.

Cloudflare Durable Objects solve this fundamental challenge. They are a powerful primitive for building stateful serverless applications directly at the edge.

• They provide a single-instance, globally consistent object.
• Each Durable Object instance has a unique ID and its own private storage.
• They act like tiny, persistent servers that live at the edge.
