What is RequestB.in?
RequestB.in is an open-source API testing tool that allows developers to easily test REST and GraphQL APIs. It provides an intuitive interface to:
- Create requests with parameters, headers, auth, and bodies
- Assert responses to validate status codes, headers, response times, and test response bodies using JSONPath and regex
- Autogenerate code snippets in various languages like JavaScript, Python, cURL, etc to easily integrate real API calls into applications
- Mock servers and endpoints to simulate APIs for faster parallel development
- Visualize API flows to document and debug sequences of API calls
As an open-source tool, RequestB.in enables collaborative API testing and documentation within teams. Developers can share saved API requests and environments with teammates, reuse test suites in CI/CD pipelines, and track changes. With support for custom extensions and themes, they can also customize RequestB.in to their specific needs.
In summary, RequestB.in provides a feature-packed open-source solution to efficiently test and monitor APIs during development and in production.
