Katalon Studio

Katalon Studio is a versatile, low-code automation platform that powerfully integrates API, Web, and Mobile testing into a single environment. It lowers the barrier to entry for test automation with its intuitive UI, record-and-playback capabilities, and built-in keywords, while still offering a full scripting mode in Groovy for advanced users. Its API testing module allows for easy creation of test suites, supports REST, SOAP, and SSL client certificates, and features robust assertion and data-driven testing. The integration with the broader Katalon Platform (TestOps, Recorder, AI) provides a cohesive ecosystem for management, reporting, and execution. It's ideal for QA teams and automation engineers seeking a unified solution for end-to-end testing that combines UI and API layers without requiring deep programming expertise from all users.
