Postman
The API platform for building and using APIs
About Postman
Postman is a comprehensive API platform used by over 30 million developers to design, build, test, and collaborate on APIs across their entire lifecycle. It provides an intuitive interface for sending API requests, automating tests, generating documentation, and managing APIs at scale with built-in governance and collaboration features.
Pros & Cons
Pros
- Intuitive and user-friendly interface that makes API testing accessible even to non-technical users
- Comprehensive feature set covering the entire API lifecycle from design to monitoring
- Excellent team collaboration with shared workspaces, collections, and auto-generated documentation
- Strong automation capabilities with collection runners, CLI integration, and CI/CD pipeline support
- Large community with over 30 million developers and extensive public API collections
- Multi-protocol support including REST, GraphQL, gRPC, WebSocket, and SOAP
Cons
- Desktop application is resource-heavy and performance degrades with large collections
- Free tier has become increasingly restrictive, now limited to a single user with no team features
- Many features require an internet connection, limiting offline development capabilities
- Managing team permissions and collection versioning becomes complex at scale
- Pricing can feel steep for small teams
