BrowserAct: Three Browser Modes and a Human Handover

Getting past blocks escalates in three layers: the environment layer masks fingerprints and switches proxies, the execution layer handles captchas and protected pages, and the human layer opens a live URL so you take over from any device, after which the agent continues. state returns an indexed text list, so you type click 3 or input 2 without parsing DOM. Only hosted proxies and stealth browsers beyond the first five cost money, and the stealth family needs an account. Sensitive operations need explicit approval each time.
