📝 About Postman
Postman remains the enterprise default for API work in 2026. Millions of developers use it to send requests, organize collections, write automated tests, mock endpoints before backends exist, and publish documentation that stays in sync with the code. If an API is being built anywhere, someone is probably probing it with Postman.
Its strengths are maturity and breadth: environments and variables, CI integration via Newman, contract testing, and shared workspaces that let teams collaborate on API design. The platform has grown into a full API lifecycle hub, which is exactly why large organizations standardize on it.
The trade-offs have grown too. Mandatory accounts, an increasingly heavy desktop app, and the 2026 removal of free team collaboration pushed many individual developers toward leaner clients like Insomnia or Bruno. For teams, though, Postman’s ecosystem is still the safest, most complete choice.
