Open-source API & UI test automation

What it does

Karate is an open-source unified test automation platform combining API testing, API performance testing, API mocks & UI testing. 1.5 million monthly downloads, used by 500+ companies including 76 of the Fortune 500, are a testimony of Karate removing friction from the developer experience (DX). We did this by making it exceptionally simple to write tests (low code), simulating end-user workflows accurately, re-using API tests as performance tests, parallel execution, and collaboration via Git. Staying true to Karate’s “LOCAL-FIRST” approach (user data remains within the customer's firewall, ensuring security and addressing any concerns), we launched the official Karate plugins (IntelliJ and VS Code) for frictionless onboarding, simplified installations, configuration, and maintenance. Our plugins include all Karate open-source features, including exploring of APIs, and premium features (testing for Async APIs, API documentation, API data importer and more).
