About Prism

Prism is an open-source HTTP mock server and contract-testing tool from Stoplight that turns an OpenAPI or Postman description into a live mock API and validates requests/responses against the spec. Developers use it to prototype and test integrations against an API before the backend exists and to enforce contract conformance. It runs as a CLI or programmatically in CI pipelines.
