- 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.

- -As someone with BPMN 2.0 - background, I'd say @CNCFWorkflow - and the tooling around it with support in @Code is coming - together quite nicely. Like the simplicity and clean language spec, really well done - IMO. 40 lines of simple YAML for a simple Approval process, sweet.#serverless - pic.twitter.com/yMMIV2k1Vs
