What is Postman?
Postman is the AI-native platform for API engineering. As autonomous agents write, test, and ship code at machine speed, APIs face machine-volume traffic that human-paced processes can’t absorb. Postman helps teams design, test, document, monitor, and govern APIs in one connected system. Its Context Graph, CLI, and MCP Server give agents the API context they lack, so generated calls and tests reflect how systems really work. Fabric, Astropods, Fern, and Passport add the governance, security, and runtime controls agent traffic demands.

Ensure API quality at scale without adding more tools to your stack
Reduce rework with unified API workflows
Eliminate tool fragmentation and costly handoffs. Postman keeps specs, code, and documentation aligned with contract-first governance, bi-directional Git sync, and automated pipeline testing.
Eliminate the speed vs. quality vs. security tradeoff
Stop sacrificing security for speed or slowing delivery for compliance. Pipeline-native testing catches failures at commit, automated compliance scanning enforces standards without blocking delivery, and encrypted secret management protects sensitive data so teams ship faster without compromising security.
Build APIs ready for both humans and AI agents
Stop retrofitting APIs for AI compatibility. Postman's governance and standardization make every API discoverable, reliable, and machine-consumable from day one. Centralized catalogs maximize reuse across teams and MCP-powered agent compatibility extends your APIs to intelligent workflows. And coding agents drive Postman directly through the CLI, installing pre-built skills to run collections, tests, and API workflows without leaving the editor.
Who uses Postman and what they use it for
Catch breaking API changes before release
Run collections as automated tests in your CI pipeline with the Postman CLI, so a failing test stops the release instead of reaching production.
Keep specs, code, and documentation in sync
Design APIs in Spec Hub and version collections and specs in your own Git repository with Native Git, so API changes follow the same review and branching workflow as code.
Enforce API standards across teams
Apply built-in and custom governance rules, including Spectral support, and review the results in security and governance reports.
Give agents the context to work with your APIs
Equip coding agents with the Postman CLI, plugin, and pre-built skills, and make your APIs available through the Postman MCP server. Then run and secure agents in production with Astropods, Fabric, and Passport.
Help other teams find and reuse your APIs
Publish APIs to a Private or Public API Network, with team verification and universal search, so teams and partners can discover and reuse them.
How Postman works
1. Create a workspace and add your API
Design an API in Spec Hub, or import an existing API definition.
2. Build and test requests
Send requests with the API client and save them in collections, with environments, variables, and tests.
3. Version and govern your work
Version collections and specs in Git with Native Git, and check them against governance rules.
4. Automate and monitor
Run collections in your CI pipeline or from a coding agent with the Postman CLI, and schedule monitors to watch your APIs in production.
5. Publish and share
Publish documentation and share APIs through a Private or Public API Network.
What it takes to get started
Platforms
Postman runs as a desktop app for Windows, macOS, and Linux, and on the web.
Git hosts and CI
Postman connects to GitHub, GitLab, and Azure DevOps for Git workflows, and runs in CI pipelines through the Postman CLI.
API gateways
Deploy APIs to Azure API Management, Amazon API Gateway, and Apigee.
Coding agents
Coding agents such as Claude, Codex, and Cursor can work with Postman through the Postman CLI, skills, and the Postman MCP server.
Plans
Postman offers Free, Solo, Team, and Enterprise plans. The Free plan includes the API client, specs, mock servers, and 100 AI credits per month. Some capabilities depend on plan, so check what each includes on the pricing page.

Frequently asked questions
Postman is the AI-native platform for API engineering. It gives agents the skills, context, and security to work with your APIs, and gives developers, QA, platform, and governance teams one shared workspace to design, test, document, monitor, and govern them.
Yes, and agents are who Postman is built for. The Postman CLI and plugin load pre-built skills into coding agents such as Claude, Codex, and Cursor so they can run collections, tests, and API workflows from the editor. The Postman MCP server makes your APIs available to agents, and the Context Graph gives them a map of how your APIs fit together. Agent Mode automates API workflows with native AI, and AI Engineer helps teams scale velocity with agents while keeping quality and security.
Developers, QA engineers, API and platform teams, and security and governance teams use Postman, from individuals building their first API to enterprises managing APIs at scale.
A Postman account. Download the desktop app for Windows, macOS, or Linux, or use Postman on the web. The Free plan includes the API client, specs, mock servers, and 100 AI credits per month.
Free, Solo, Team, and Enterprise. Free is for individuals building and testing APIs. Solo is for individuals who want to move faster with AI and automation. Team is for teams building and shipping APIs together. Enterprise is for organizations building, managing, and distributing APIs at scale. See the pricing page for what each plan includes.
The Postman platform is the full workspace for designing, testing, documenting, and monitoring APIs. The Postman CLI is the command-line tool that runs your collections and tests from a terminal, a CI pipeline, or a coding agent. Use the platform to build and manage APIs, and the CLI to automate them.
With separate tools, specs, tests, documentation, and monitors live in different places and are kept aligned by hand. Postman keeps them in one workspace, connected through Git sync and governance rules. Postman does not replace your Git host, CI system, or API gateway. It connects to them, and you can import existing API definitions.
The Postman Agent Stack extends the platform for agents in production. Fabric is the AI-native gateway for AI, MCP, and API traffic. Astropods is the agent operating system that runs and controls AI agents in production. Fern is the docs, SDK, and CLI layer that makes every API discoverable, typed, and callable. Passport is the credential proxy that lets developers and agents call approved APIs without holding the secret.
