Serverless Devs is an open-source developer tool for building, deploying, and managing serverless applications across multiple cloud providers. Originated by Alibaba and donated to the CNCF Sandbox, it offers a single CLI and YAML-based application model (s.yaml) that abstracts provider-specific details behind reusable components.
The tool is built around a component model: each component is a versioned package, published to a public registry, that implements operations like deploy, remove, invoke, or logs for a given target such as Alibaba Cloud Function Compute, AWS Lambda, Tencent SCF, or Huawei FunctionGraph. An application’s s.yaml references components with inputs, so the same project description can be deployed through provider-specific implementations.
Serverless Devs includes a component marketplace, environment/stage support, and plugin hooks for CI pipelines, making it a pragmatic choice for teams operating functions across Chinese and global cloud providers from a unified workflow.
