Chrome DevTools

Gives Claude real browser control — inspect the DOM, record performance traces, and analyze network traffic for live debugging and testing.

Open up a live Chrome browser right from your coding agent and inspect it like you're sitting at your desk. You get the full range of DevTools powers—29 different tools for automating the browser, checking how fast things run, watching network traffic, and hunting down bugs. It all works through Puppeteer and the Chrome DevTools Protocol, so Claude can do everything you'd normally do by hand in the Chrome inspector.
