Postman

Postman is an API platform that covers the full lifecycle of building and running APIs, from initial design through testing and long-term operation. Its tools are grouped into three areas: Design & Build, Test & Validate, and Manage & Operate.

Design & Build includes Spec Hub for API specifications, shared Workspaces, native Git integration, documentation, mock servers, an SDK generator, and Flows. Test & Validate provides an API client for sending requests, Collection Runner, functional and data-driven testing, performance testing, monitors, and webhook testing. Manage & Operate adds an API catalog, Insights, an application inventory, and a Context Graph.

Beyond the core workflow, Postman has added AI-focused tooling: Agent Mode for automating API workflows, a Postman CLI with pre-built skills for agents, and a Postman MCP Server that gives AI agents API context. The site also lists an MCP Server Catalog and a Postman API Network for exploring public APIs. Packaged solutions cover API governance, partner API management, API lifecycle management, and SDLC automation.

Best for

• Development teams designing, documenting, and mocking APIs from specifications
• Developers and QA engineers running functional, data-driven, and performance tests against APIs
• Teams that want scheduled monitors and webhook testing in their workflow
• Organizations that need API governance, an API catalog, and partner API management
• Teams building AI agents that need API context through MCP tooling

Frequently asked questions

Is Postman free to use?

There's a free sign-up option alongside a paid pricing structure and an enterprise offering. Pricing details aren't listed on the homepage; see postman.com/pricing for current plans.

Does Postman integrate with Git?

Yes. Native Git integration is part of the Design & Build area, so teams can keep API specifications and related assets in version control alongside their code.

Can Postman handle automated testing?

Yes. Collection Runner supports functional and data-driven testing, and monitors can run checks on an ongoing basis. Performance testing is also part of the Test & Validate toolset.

Does Postman support AI agents?

Yes. Agent Mode automates API workflows, the Postman CLI ships with pre-built skills for agents, and the Postman MCP Server gives AI agents API context. There's also an MCP Server Catalog for discovering servers.

Is Postman only for sending API requests?

No. The API client is one part of a platform that also covers specification design, documentation, mock servers, testing, monitoring, and operational management through the API catalog and Insights.

What support and learning resources are available?

Postman offers documentation, a learning hub, Postman Academy, a support center, release notes, and a status page. There's also a community Discord, an events calendar, and a partner program.
