What is Durable Actors?
Durable Actors is an open-source framework that provides stateful serverless functions for building distributed applications. It serves as an alternative to managed services like Cloudflare Durable Objects, removing vendor lock-in and memory limits while including built-in observability.
The system uses an actor model where developers define classes with durable state that survives interruptions and errors. Concurrent requests are handled through serialized execution, ensuring safe updates without manual locking. The runtime automatically generates type-safe client code for supported languages.
Developers can run the environment locally using Bun and deploy the self-hosted runtime on Google Cloud Platform. The project includes SDKs for Python and TypeScript, along with documentation and examples for setting up real-time communication and coordination patterns.
