Step CI

Step CI provides an open‑source framework for API quality assurance that can be used from the command line. Workflows are defined in YAML, JSON, or JavaScript and support a wide range of protocols including REST, GraphQL, gRPC, tRPC, and SOAP, allowing a single test suite to cover heterogeneous services. The CLI runs locally, in containers, or as part of CI/CD pipelines, and can be self‑hosted to test services on private networks.

The tool is language‑agnostic and integrates with existing development workflows; users create a workflow file describing environment variables, requests, and checks, then execute it with a single command. Results are reported with pass/fail counts and execution time, and the framework includes an online playground and documentation for quick onboarding.

Step CI is distributed under the Mozilla Public License and collects optional anonymous usage analytics that can be disabled via an environment variable. Community support is available through Discord and GitHub, and a commercial support plan offers SLA‑backed assistance and prioritized feature development.
