    Generate API Tests In Seconds with AI

    Loadmill Test Composer uses AI to generate automated API tests in real-time, right from your browser.

    Generate test code for every user flow

    Spend less time creating boilerplate and repetitive test code and more time adding your human insights to your tests. Play a user flow in your app, and the Test Composer will immediately generate an end-to-end API test script for it.
