Postman

What is Postman?

Postman is the leading API platform used by over 25 million developers worldwide for building, testing, documenting, and managing APIs. Founded in 2014 as a spin-off from a mobile development company, Postman has grown into an essential tool in every developer toolkit, supporting the entire API lifecycle from design to deployment. The platform AI features include Postbot, an AI-powered assistant that helps generate API requests, write tests, debug responses, and create documentation using natural language. Postman also offers AI-powered API schema generation, intelligent response validation, and automated test script creation. The platform supports REST, GraphQL, gRPC, and WebSocket APIs, making it versatile for any API architecture. Postman is used by 99% of Fortune 500 companies and has been instrumental in standardizing API development workflows across the industry, with its collection format becoming a de facto standard for API documentation and sharing. On PureAINav, Postman is one of the most searched API development tools, reflecting its essential role in modern software development workflows.

Who Should Use Postman

Postman is essential for backend developers who build and test APIs daily, frontend developers who need to understand API contracts before integration, QA engineers who automate API testing as part of CI/CD pipelines, API designers creating schemas and documentation, and technical product managers who need to understand API capabilities. The platform is particularly valuable for teams adopting API-first development, where APIs are designed and documented before any code is written. Postman free tier is generous enough for individual developers, while the paid plans unlock collaboration and advanced features for teams and enterprises.

Pricing

Postman offers a free tier with basic API client features, 3 collaborators per workspace, and limited collection runner runs. The Basic plan at $14/user/month (billed annually) adds unlimited collaborators, integration with monitoring, and priority support. Professional plan at $29/user/month includes advanced API Builder, API governance, and role-based access control. Enterprise plan at custom pricing adds SSO, audit logs, and dedicated support. Postman is widely used on its free tier by individual developers and small teams.
