Mock servers
Postman’s mock servers streamline API design, accelerate split-stack development, and ensure your API delivers the right behavior when it hits production.
Build it right before you build it for real
Postman’s mock servers let you simulate real API responses before the backend exists so frontend and backend teams can work in parallel, validate designs early, and see exactly how the API will behave in production.
Design your API with flexible schema support
Write, edit, or import your API schema to define your API's data structure and generate a collection from your API schema. You can review API responses using mock servers so you can reliably build your API from the ground up, all in one central place.
Catch and fix bugs early
Mock servers increase visibility into errors and weak spots in your API, so you can debug effectively and efficiently. You can easily use mock servers to test for response errors continuously or as often as you need throughout the API lifecycle.
Create public or private mock servers
Postman provides two different types of mock servers. Public mock servers are great for open source or individual projects, but if you're working on internal or private APIs, you can easily keep your APIs secure by viewing API responses with private mock servers.
Collaborate across teams with shared mocks
Mock servers live alongside your collections, documentation, and tests in Postman Workspaces. Anyone on the team can explore, fork, or update mocks so everyone stays aligned.
