Instead of Postman
Postman alternatives
Postman combines API design, testing, distribution, documentation, and monitoring in one platform. Its client brings multi-protocol requests, built-in authentication, response inspection, variables, environments, and request history together. It also supports mock servers, automated and performance testing, and integrations including Jira, Slack, GitHub, and VS Code. The free plan includes core tools, while Solo starts at $9 per month billed annually; Team starts at $19 per user per month billed annually. Enterprise pricing is not provided, and Basic and Professional plans are closed to new customers.

A different tool may fit better if you want collections managed as project files, command-line testing, self-hosting, or a more specialized workflow. Compare protocol coverage, test automation, mock creation, collaboration, and deployment options before switching. Also consider whether you need a graphical client, a CLI, or both, and how the alternative handles specifications, environments, and CI/CD. Free plans are available across these options, but paid starting prices and included capabilities differ.
