Get Early Feedback

Get feedback from consumers and stakeholders on API designs before development using interactive protoypes. This allows you to act on feedback and align stakeholders promptly, ensuring APIs fulfill consumer requirements and avoid unanticipated breaking changes later.

Develop simultaneously with hosted mock servers.

Reduce time to market by letting frontend and backend teams develop simultaneously, without waiting for the development stage of the API to complete.

Learn More

Validate and test API designs.

Validate requests and responses against your OpenAPI file. Stoplight mocks simulate real server behavior by automatically validating incoming request headers, query strings, and request bodies against your OpenAPI description.

Spin up lifelike APIs with dynamic mocking.

Testing against the same data over and over again is not the best way to build a robust integration. Dynamic mocking leverages fake data to simulate real server behavior by responding dynamically to requests.
