Create or Import Instance

Create your first instance with a unique subdomain or import from OpenAPI/Swagger. Each instance gets an HTTP(S) address for easy integration with your applications.

Configure Mocks with Recording & Scripting

Record actual API traffic, use templating for dynamic responses, add scripting logic, and implement stateful behavior. Match requests by path, query params, headers, and more.

Configure Your Application and Run Tests

Copy your instance's HTTP(S) address and add it to your service configuration. Run tests without calling live third-party services, reducing costs and improving reliability.
