Cloudflare Durable Objects

Real-time, low-latency API coordination and consistent storage

Durable Objects provides a powerful API for coordinating multiple clients and users — helping you build collaborative applications while maintaining strong consistency of state.

BENEFITS OF CLOUDFLARE DURABLE OBJECTS
State consistency from a global network

Durable Objects allows you to store application state in a specific data center on our network, guaranteeing that all requests reach the same instance every time.

Embedded compute

With Durable Objects, your compute functions execute within the same serverless environment as your state — helping you build complex logic without impacting performance.

On-demand scalability

Durable Objects can scale from zero to millions of objects in seconds, ensuring consistent access to your applications — even during peak traffic periods.

HOW IT WORKS

Build high-performing stateful applications from anywhere on our global network

A Durable Object is a special kind of Cloudflare Worker that processes requests in one of our data centers — available in over 330 cities worldwide.

Each Durable Object is single-threaded and has access to a stateful storage API, making it easy to build consistent, highly-available distributed applications with them.
