 |[XM](https://www.xm.com/) | [Stelios Gkiokas](https://github.com/sgkiokas) | `end user` | Microcks streamlines microservice development and testing by dynamically generating mocks from OpenAPI specs, gRPC contracts, and GraphQL schemas. Using Testcontainers, it replaces WireMock, gRPC Mock by Fadelis, and HttpGraphQlTester, while Kubernetes Operators allow teams to manage their own instances. This approach also enables realistic simulation of Payment Service Providers and provides a unified platform for developers, SETs, and QAs to collaborate effectively.|

For example, see how we use Microcks for mocking [OIDC](https://hub.microcks.io/package/openid.net/api/oidc.1.0) by checking out the slide deck from one of our talks on the subject! 👉 [Riviera DEV 2025](https://www.slideshare.net/slideshow/how-to-secure-your-apis-without-compromising-the-developer-experience-pdf/281499574).|
 | [Kiabi](https://kiabi.com) | [Emmanuel Peru](https://github.com/emmanuelperu) [Baptiste Desmasures](https://www.linkedin.com/in/baptiste-desmasures) | `end user` | We use **Microcks** to mock REST and Graphql API contracts, enable reliable testing, and streamline development workflows. It helps some of our teams ensure consistency, validate integrations early, and improve collaboration across different services. By simulating APIs, Microcks reduces friction in development and increases confidence in production deployments.|
