Instead of Katalon Studio

Katalon Studio alternatives

Katalon Studio brings web, mobile, API and desktop test creation and execution into one IDE. Teams can use no-code, low-code, full-code or AI-assisted authoring in shared projects. Its web recorder produces reusable Selenium-based tests, its mobile recorder captures Appium flows, and API tests for REST, SOAP and GraphQL can live alongside UI tests. Katalon AI can generate tests, analyze failures and repair locators. A free plan is available, while Professional costs $1,000 a year, billed annually; the free tier is limited to 40 static test suites and excludes parallel execution and AI script generation.

Alternatives range from open-source test frameworks to browser services and device-cloud execution. The right switch depends on whether you want to keep web, mobile, API and desktop work together, or prioritize a particular browser workflow, test framework or execution environment. Compare the authoring style and supported test types with your needs, and consider the cost of moving from a shared IDE to a framework or service. Platform coverage also differs: some options focus on web browsers, while others include native mobile testing, broad remote device access or fingerprint masking.
