Functional testing software helps you check whether an application behaves as expected. The ranking starts with WebdriverIO, testRigor, and Playwright, with Nightwatch and Selenium also among the first entries. Compared on web app, mobile app, and desktop app coverage, these tools can be weighed against the applications you need to test. Cross-browser support and authoring mode offer further points of comparison; parallel runs and a self-hosted option may also affect fit. Check free-plan availability and the listed paid-from price alongside those capabilities when narrowing your options.
