Prism (.8k)
Open-source API mocking and contract testing server for OpenAPI and Postman specifications.
What is Prism (.8k)?
Prism is an open-source tool that turns OpenAPI and Postman Collection files into mock API servers and validation proxies. It allows developers to simulate API behavior before backend implementation and validate that live APIs adhere to their specifications. This helps teams adopt API-first development practices and improve API quality.
API developers, testers, and designers who work with OpenAPI or Postman specifications and need to mock APIs for frontend development or validate implementations against contracts.
Developers choose Prism for its comprehensive support of OpenAPI versions and Postman Collections, its dual functionality as both a mock server and validation proxy, and its ability to run as a self-hosted CLI tool or be integrated into CI/CD pipelines.
Overview
Turn any OpenAPI2/3 and Postman Collection file into an API server with mocking, transformations and validations.
