Karate Labs provides an open-source test automation platform that unifies API testing, UI testing, performance testing, and API mocking in a single, low-code framework. It is designed for ease of use, enabling both technical and non-technical users to write and maintain automated tests efficiently. The platform supports integration with DevOps pipelines, parallel execution for faster testing, and seamless collaboration through official IDE plugins. Its domain-specific language is based on Gherkin, making test scripts readable and accessible, and it supports Java interoperability for advanced scenarios.
