Open-source test automation, governed for AI-built software

Open source, MIT, trusted by 76 of the Fortune 500. API, UI, mocks and performance. One tool. Plain syntax. Zero boilerplate.

GitHub stars Latest release License Install for VS Code IntelliJ downloads Docs VeriQuant: insurance rating validation

Latest   Karate v2.1.4 released 22 Oct 2026  ·  On the blog: Claude proved 123 libraries crash-free. Here's what still needs checking.

A whole API test. No code, no step definitions.

Feature: users API

  Scenario: create and fetch a user
    Given url baseUrl + '/users'
    And request { name: 'Ana', email: 'ana@example.com' }
    When method post
    Then status 201
    And match response == { id: '#number', name: 'Ana', email: '#string' }

API, UI, mocks and performance tests share one syntax, run in parallel, and produce a report your whole team can read.

Watch: Safe to ship (2:35)

When AI writes the code and the tests

Generation got cheap. Knowing what's safe to ship didn't. Karate governs it, on the same open-source engine.
