4.2 KiB
A browser automation plugin for Claude Code that lets Claude control your browser to test and verify your work as you develop.
Key features:
- Persistent pages - Navigate once, interact across multiple scripts
- Flexible execution - Full scripts when possible, step-by-step when exploring
- LLM-friendly DOM snapshots - Structured page inspection optimized for AI
Prerequisites
- Claude Code CLI installed
- Node.js (v18 or later) with npm
Installation
Claude Code
/plugin marketplace add sawyerhood/dev-browser
/plugin install dev-browser@sawyerhood/dev-browser
Restart Claude Code after installation.
Amp / Codex
Copy the skill to your skills directory:
# For Amp: ~/.claude/skills | For Codex: ~/.codex/skills
SKILLS_DIR=~/.claude/skills # or ~/.codex/skills
mkdir -p $SKILLS_DIR
git clone https://github.com/sawyerhood/dev-browser /tmp/dev-browser-skill
cp -r /tmp/dev-browser-skill/skills/dev-browser $SKILLS_DIR/dev-browser
rm -rf /tmp/dev-browser-skill
Amp only: Start the server manually before use:
cd ~/.claude/skills/dev-browser && npm install && npm run start-server
Chrome Extension (Optional)
The Chrome extension allows Dev Browser to control your existing Chrome browser instead of launching a separate Chromium instance. This gives you access to your logged-in sessions, bookmarks, and extensions.
Installation:
- Download
extension.zipfrom the latest release - Unzip the file to a permanent location (e.g.,
~/.dev-browser-extension) - Open Chrome and go to
chrome://extensions - Enable "Developer mode" (toggle in top right)
- Click "Load unpacked" and select the unzipped extension folder
Using the extension:
- Click the Dev Browser extension icon in Chrome's toolbar
- Toggle it to "Active" - this enables browser control
- Ask Claude to connect to your browser (e.g., "connect to my Chrome" or "use the extension")
When active, Claude can control your existing Chrome tabs with all your logged-in sessions, cookies, and extensions intact.
Permissions
To skip permission prompts, add to ~/.claude/settings.json:
{
"permissions": {
"allow": ["Skill(dev-browser:dev-browser)", "Bash(npx tsx:*)"]
}
}
Or run with claude --dangerously-skip-permissions (skips all prompts).
Usage
Just ask Claude to interact with your browser:
"Open localhost:3000 and verify the signup flow works"
"Go to the settings page and figure out why the save button isn't working"

How It's Different
| Approach | How It Works | Tradeoff |
|---|---|---|
| Playwright MCP | Observe-think-act loop with individual tool calls | Simple but slow; each action is a separate round-trip |
| Playwright Skill | Full scripts that run end-to-end | Fast but fragile; scripts start fresh every time |
| Dev Browser | Stateful server + agentic script execution | Best of both: persistent state with flexible execution |
