Does BELLATRIX use Playwright or Selenium?
Both. BELLATRIX web automation runs on Selenium WebDriver, and release 4.0 added a new Playwright engine for the C#, Java and JavaScript versions. Mobile tests use Appium. The framework sits on top of these tools, so you keep their cross-browser support and the same BELLATRIX syntax for your tests.
