About
CNCF Serverless Workflow defines a vendor-neutral, open-source, and fully community-driven ecosystem for defining and running DSL-based workflows that target the Serverless technology domain.
This project is composed of:
- Specification for defining DSL-based workflows
- Developer SDKs for different programming languages
- Workflow runtimes supporting the specification
- Developer tooling support for writing DSL-based workflows
CNCF Serverless Workflow is hosted by the Cloud Native Computing Foundation (CNCF) and was approved as a Cloud Native Sandbox level project on July 14, 2020.

SDKs
Serverless Workflow encourages development of SDKs dedicated to help developers with consuming, parsing, validating and testing their workflows that use the Serverless Workflow DSL.
Tooling
In order to enhance developer experience with the specification, we also provide a Visual Studio Code extension. The sources of the extension are found here.
