Standards-based DSL and open-source dev tools and runtimes are at the heart of the Serverless Workflow project. We connect developers around the world to foster innovation and provide a community-driven workflow ecosystem.
using the most powerful open-source, vendor-neutral workflow DSL. Our DSL provides integrations with widely used standards for events and services such as CloudEvents, OpenAPI, AsyncAPI, GraphQL, gRPC, and more.
JSON, YAML
Define you orchestration logic that is triggered via events and invokes services sync or async. Write logic that includes human decisions, set timeouts and retries, handle errors, and much more...
Java, Go, TypeScript, .NET, ...
Start developing your workflow orchestrations with help of our project SDKs. Get help creating out-of-box user experience using our open-source editor/web tooling and visualization support
Serverless, Cloud-Native, Distributed runtimes
Execute and scale your workflow-based orchestrations to build high-end applications.
