Postman
FeaturedFreemiumThe most popular API development platform — testing, documentation, and mocking
📮API ToolsAbout Postman
Postman has become the standard API development tool with 30 million users worldwide. Collections organize API requests into logical groups. Environments store variables (base URL, auth tokens) that switch between dev, staging, and production. Tests run assertions after each request to verify responses. The Collection Runner executes entire collections for integration testing. Mock servers simulate APIs before they're built. API documentation is generated automatically from collections and can be published publicly. Postman Flows creates visual API workflows. The free tier is generous — unlimited API calls, 3 teammates on free plan. Compare to Insomnia (open source alternative), Bruno (Git-native, offline-first), Hoppscotch (browser-based). Best for: virtually every developer who builds or consumes APIs — Postman is the default choice.
What's Great
- ✓30M users — massive community and integration ecosystem
- ✓Collections with environments for multi-stage API testing
- ✓Auto-generated API documentation from collections
- ✓Mock servers for testing before backend exists
- ✓Collection Runner for automated integration test suites
Watch Out For
- !Increasingly cloud-dependent — reduced offline functionality
- !Resource-intensive desktop app
- !Team collaboration features require paid plans for more than 3 users
Common Use Cases
A backend developer documents a REST API and shares a public Postman collection with frontend developers
A QA team runs automated API regression tests before each deployment
A frontend developer uses Postman mock server to develop against an API that doesn't exist yet
