Everything you need to test an API

7 HTTP methods and 6 body kinds

Import OpenAPI, Postman, Insomnia, HAR, cURL and suite JSON

Secret variables masked in UI and stripped from exports

Assertions, hooks and data-driven runs

Generate code for five languages

A data model, not a scripting sandbox.

Hooks are declarative steps. Nothing you import can execute code on your machine.
