Dapr Open-Source

Dapr (Distributed Application Runtime) is an open-source runtime that exposes portable building block APIs — service invocation, state, pub/sub, workflows, actors, secrets, and more — so developers can build distributed applications without writing infrastructure code. Diagrid Catalyst is built on Dapr and manages the runtime on your behalf.
