An open-source API Quality Assurance framework for automated testing of REST, GraphQL, gRPC, tRPC, and SOAP APIs.
Step CI is an open-source API Quality Assurance framework that automates testing for various API protocols including REST, GraphQL, gRPC, tRPC, and SOAP. It solves the problem of fragmented API testing by providing a unified, language-agnostic testing workflow that can be integrated into CI/CD pipelines or run locally.
API developers, DevOps engineers, and quality assurance teams who need to automate testing for multiple API protocols within their development and deployment workflows.
Developers choose Step CI because it offers a self-hosted, open-source alternative to commercial API testing tools with support for multiple protocols in one framework, avoiding vendor lock-in while providing flexibility in configuration and deployment.
Automated API Testing and Quality Assurance
Open-Awesome is built by the community, for the community. Submit a project, suggest an awesome list, or help improve the catalog on GitHub.
Supports REST, GraphQL, gRPC, tRPC, and SOAP APIs in a single workflow, eliminating the need for separate testing tools as highlighted in the README.
Tests can be configured using YAML, JSON, or JavaScript, making it accessible regardless of the team's primary programming language, per the features list.
Runs on your own network, locally, or in CI/CD environments, providing full control and avoiding vendor lock-in, as emphasized in the philosophy.
Designed to play nicely with existing pipelines, enabling seamless automated API quality checks in development workflows.
Lacks a GUI for test creation and management, requiring users to write configuration files, which can be a barrier for non-developers or those accustomed to visual tools.
As a newer open-source project, it has a smaller community and fewer pre-built integrations compared to established alternatives like Postman or Insomnia.
The CLI collects anonymous usage data by default, which might raise privacy concerns, though it can be disabled via an environment variable as noted in the README.
