Your Browser Has a Remote Control — And Nobody Told You

3 tools that let AI agents drive Chrome. I tested all three. Here's what actually happens. Every Chrome browser ships with a hidden feature that almost nobody talks about: a remote control API called the Chrome DevTools Protocol (CDP). It's the same protocol that powers Chrome DevTools — the thing you open when you press F12. But here's the part that changes everything: any program can use it. Including AI agents. I've been using CDP daily for over a year to let AI agents read my authenticated Gmail, manage my Google Developer Expert activities, and automate workflows across dozens of logged-in accounts. No passwords. No API keys. No OAuth flows. The AI just... uses my browser like I would. Three major tools have emerged to give AI agents this superpower. I tested all three on the same task, with the same authenticated browser, and discovered something that most tutorials and docs don't tell you.
