Alternatives to Postman
The dominant API platform with cloud workspaces
Postman ranks #5 of 6 in API clients, with an Alt Score of 78. It is proprietary, freemium from $9/month and available on Windows, macOS, Linux and Web. 12 of 12 checklist rows are verified against a public source.
API developers, QA/testers, and cross-functional teams (backend, frontend, DevOps) at companies of any size who design, build, test, or consume APIs.
A workspace for sending and organizing API requests into collections, with environments to manage variables across dev/staging/prod. Mock servers simulate endpoints before backend code exists, and monitors run scheduled checks on API health and performance. Auto-generated documentation and shared team workspaces support collaboration, and built-in AI features assist with generating requests, tests, and documentation.
You create requests and group them into collections, then run and automate them individually or via the Collection Runner, CI/CD integrations, or CLI (Newman). Team workspaces sync collections, environments, and docs so multiple people can build and test against the same APIs.
