Building scalable applications that maintain state while managing infrastructure has always been a complex challenge for teams. But what if you could combine the simplicity of serverless computing with persistent, strongly consistent storage—all automatically distributed across the globe? Cloudflare Durable Objects changes how you architect distributed applications, eliminating the infrastructure management headaches while enabling new possibilities for real-time, stateful workloads.

Traditional serverless solutions excel at stateless compute, but most real-world applications need to maintain state—whether it's user sessions, coordination between clients, or transactional data. This creates a dilemma: teams either build complex multi-service architectures with separate databases and caching layers, or they abandon serverless for traditional infrastructure management.

The result is increased operational overhead, latency issues from geographically distant storage, and complex consistency models that make building reliable applications difficult. Teams waste valuable engineering time managing infrastructure instead of focusing on product features. Durable Objects solve this by uniquely combining compute and storage in a single primitive. Each Durable Object is automatically provisioned near your users, starts instantly when needed, and includes its own durable, transactional storage—up to 10GB per object.

04 / 06

Unlike regular Workers, each Durable Object has a globally-unique name, allowing you to send requests to specific objects from anywhere worldwide. This enables seamless coordination between multiple clients and millions of object instances scaling elastically across Cloudflare's global network. You get single-threaded concurrency for safety, in-memory state for performance optimization, and WebSocket support for real-time communication—all without managing infrastructure or worrying about object lifecycle.
