Katalon integrates with CI/CD pipelines, Jira, Azure DevOps, and other development tools, and is used by more than 120,000 users across industries like banking, retail, and healthcare.

TestComplete is an automated testing platform from SmartBear that lets QA teams create and run UI tests for desktop, web, and mobile applications from a single tool.
