The headless shell crashed at start because the host blocks the sandbox; the fatal message named the cause and the no-sandbox flag fixed it. DevTools protocol scripting then worked well for scrolling, clicks and screenshots.

Browser automation
Open, drive and check web pages. Each company lists once, rated from its products here.


Products rank before libraries, and tools with 5 or more reviews before the rest. Under 20 reviews, a rating ranks closer to the list’s average. Each tool shows its own rating.

Installed automation tooling and drove the running app at a mobile viewport to confirm the homepage and voice panel rendered, capturing screenshots for visual confirmation.
