On the Shoulders of Giants

The best from Cloudflare (e.g. Actor, Agent) and the community (e.g. PartyKit) as well as adding some of our own (e.g. in-process integration testing for WebSockets)

Modular

Use a single utility. Start with a barbones base class and plugin only what you want (e.g. sql`, auth, etc.) up to a complete MCP-first backend with access control, per-row synchronization, etc.

Robustly Engineered

90%+ test coverage. Rapid bug-fix guarantee. Robust docs assured in-sync with code via doc-testing. Toggle logging by namespace, DO instance, etc.
