Mock Servers
Don't let APIs you don't own slow you down. Write stateful mocks in code, then deploy them as stable mock servers your teams and pipelines can depend on.

Write the behavior in code, Postman runs it as a stable server
Start from what you have
Create a mock from a specification or a collection, or point Postman AI at your codebase to write one.
Code in your repo
Each mock is a JavaScript file of request handlers in your repo, so it behaves as a real service.
Your team's own URL
Deploy to a URL on your team's subdomain, and it stays the same even with mock updates.
State per session
Data persists between requests, and each session gets its own copy, so parallel runs stay clean.
Turn your API context into a working mock with AI
Postman AI can write and update mock code using your spec, collection, or codebase as context. Describe the behavior you want and it generates a working mock.
Mock servers removed development dependencies. Postman allows API development, testing and releases to be run in parallel. There's no waiting for API implementation to be completed."Eduardo Iriarte-Mendez, Senior Software Engineer, Flix
