About microcks
Microcks is an open source, cloud native API mocking and testing tool and a Cloud Native Computing Foundation incubating project. It lives in the developer tools and API development ecosystem, where teams need to exercise service contracts before implementations are ready or before changes are trusted. The project turns existing API and microservice assets, including OpenAPI specs, AsyncAPI specs, gRPC protobuf, GraphQL schema, Postman collections, and SoapUI projects, into live mocks for applications, testers, and integration pipelines.
