What is Headless Browser?
A headless browser is a real browser engine running without a graphical window—it loads pages, executes JavaScript, and responds to interactions exactly as usual, just without rendering to a screen. This makes it fast and resource-light, ideal for CI servers and parallel test execution where no display is available. Playwright can drive Chromium, Firefox, and WebKit headless for speed or headed for debugging. Recorded QI flows run either way, so the same test that you watch locally can execute headlessly at scale in the pipeline.
