Postman API Platform is a collaborative API development and testing platform with built-in mock server, collection runner, and documentation tools.
Postman API Platform provides a unified workspace for API design, testing, documentation, and mock server creation, enabling development teams to build and validate APIs without requiring live backend services.
Its mock server feature lets teams create simulated API endpoints from saved examples or collections, directly competing with service virtualization tools. The platform's collection runner supports automated API testing at scale and is widely used as a load testing and integration testing tool in CI/CD workflows.
