Postman is the world's leading API development and testing platform, used by over 30 million developers and 500,000 organizations to design, build, test, document, and monitor APIs throughout their entire lifecycle. It solves the complexity of modern API development by providing a comprehensive workspace where teams can collaborate on API specifications, create and run test collections, mock endpoints, generate documentation, and monitor API performance from a single unified interface. Postman has evolved from a simple REST client into an AI-native platform for the agentic era with deep integration capabilities.
Postman's 2025-2026 platform refresh introduced Git-connected Workspaces for version-controlled API development, an AI Agent Builder for creating and testing agentic solutions with visual workflows, and native MCP support for generating model-agnostic servers compatible with Claude, Cursor, and other AI tools. The API Catalog provides a management plane for organizations to track API ownership, testing coverage, CI/CD activity, and production observability across their entire portfolio. Enterprise features include private API runners for secure VPC-based testing, bidirectional spec-collection sync, Jira integration, and on-demand monitors that serve as deployment release gates.
Postman targets the full spectrum of API stakeholders from individual developers testing endpoints to enterprise architecture teams managing hundreds of APIs across distributed organizations. It is the industry standard for API collaboration, offering free tiers for individual developers, team plans for collaborative workflows, and enterprise plans with governance, compliance, and SSO capabilities. Postman's massive API Network enables developers to discover and fork public API collections, while its integration ecosystem connects with virtually every CI/CD, monitoring, and documentation tool in the modern development stack.
