TL;DR
claude --chromeor/chromeconnects Claude Code to your browser. From there, Claude opens tabs, navigates, clicks, reads the console, and debugs your frontend — all without leaving the terminal.
Claude Code integrates with the Claude in Chrome extension to give you browser automation directly from the CLI. Launch your app, ask Claude to test it, and it opens Chrome, navigates to your localhost, interacts with forms, reads console errors, and tells you what's broken — with access to the real DOM and your browser's login state.
It's fascinating to watch it work: opening tabs, scrolling, launching modals, typing search terms, and compiling results. It's still sometimes slow. It still sometimes fails. But the key word is still. This improves with every release, and the direction is clear.

How to set it up
1. Prerequisites
- Google Chrome or Microsoft Edge
- Claude in Chrome extension v1.0.36+
- Claude Code v2.0.73+
- Direct Anthropic plan (Pro, Max, Teams, or Enterprise)
2. Launch with Chrome

3. Enable by default (optional)
Run /chrome and select "Enabled by default" to skip passing --chrome each session. Note this increases context usage since browser tools are always loaded.
