Postman v12.20.4

Postman transforms API development from a curl-in-terminal grind into a visual, organized workflow. Create request collections, set up environments with variables, write pre-request and test scripts, and auto-generate documentation. The free tier is substantial and covers individual developers and small teams. If you work with REST, GraphQL, or WebSocket APIs, Postman is the tool that makes it feel like a GUI experience rather than a command-line slog.
