Postman

Overview Postman is an AI-native API platform for developing, testing, managing, and distributing APIs and services. It provides a unified workspace where engineers can design, build, test, and monitor APIs across the entire lifecycle. The platform serves individual developers, teams, and large enterprises who need to create, document, and scale API-driven applications. Postman differentiates from basic HTTP clients by offering collaborative workspaces, automated testing, mock servers, and an integrated AI Engineer that assists with building, testing, and maintaining APIs using organizational context. Key Benefits AI Engineer assists with building, testing, and maintaining APIs using context from every service already running in the organization. Agent Mode automates API workflows using native AI capabilities directly within the platform. Collection Runner enables automated API testing with unlimited runs across multi-protocol support. API Catalog provides a system of record to know every API and service running in the organization. Insights tracks every API endpoint for production visibility and monitoring. Native Git integration allows teams to version-control API specifications and collections directly. How It Works You create or import an API specification in Spec Hub, then generate a collection of requests. You send individual requests using the API Client, organize them into collections, and automate testing with the Collection Runner. You share collections and specifications with your team through workspaces, enabling real-time collaboration. For production APIs, you set up Monitors to validate performance continuously and use Insights to track every endpoint across your services. Use Cases Individual developers building and testing personal API projects use the Free plan with API client, specs, and mock servers. Solo professionals who want AI assistance and automation use the Solo plan for data-driven testing, custom-branded documentation, and expanded monitoring. Development teams shipping APIs together use the Team plan with SDK generation, role-based access control, and unlimited workspace viewers. Enterprise organizations managing APIs at scale use the Enterprise plan with API Catalog, audit logs, governance controls, and advanced security add-ons. API governance teams enforce API standards at scale across the organization using built-in governance features. Partner API management teams onboard external partners quickly using private and Partner workspaces. Why Choose This Product Postman is best suited for teams and organizations that need a centralized platform for the full API lifecycle, from design through testing to production monitoring. It offers a free tier for individual use and paid plans that scale to enterprise needs with advanced security, governance, and AI capabilities. The platform explicitly requires paid plans for team collaboration, production monitoring beyond basic limits, and advanced security features like SSO and audit logs.
