About Katalon

Katalon is a unified software quality platform that lets mixed-skill QA teams author, manage, execute and monitor tests across web, mobile, API and desktop applications using no-code, low-code or full-code approaches. It's built for QA engineers and testing teams at organizations of any scale, spanning industries like banking, retail, healthcare and government. Its main differentiator is a single "True Platform" that ties four products (Studio, TestOps, TestCloud, TrueTest) together with agentic AI that generates tests from requirements, self-heals broken locators, and can be driven by your own coding agent via a Katalon MCP server.
