Browser Automation
Automate browser interactions using Stagehand CLI with Claude.
First: Environment Selection (Local vs Remote)
The skill automatically selects between local and remote browser environments:
- If Browserbase API keys exist (BROWSERBASE_API_KEY and BROWSERBASE_PROJECT_ID in .env file): Uses remote Browserbase environment
- If no Browserbase API keys: Falls back to local Chrome browser
- No user prompting: The selection happens automatically based on available configuration
Setup (First Time Only)
Check setup.json in this directory. If setupComplete: false:
npm install # Install dependencies
npm link # Create global 'browser' commandCommands
All commands work identically in both modes:
browser navigate <url> # Go to URL
browser act "<action>" # Natural language action
browser extract "<instruction>" ['{}'] # Extract data (optional schema)
browser observe "<query>" # Discover elements
browser screenshot # Take screenshot
browser close # Close browserQuick Example
browser navigate https://example.com
browser act "click the Sign In button"
browser extract "get the page title"
browser closeMode Comparison
| Feature | Local | Browserbase |
|---|---|---|
| Speed | Faster | Slightly slower |
| Setup | Chrome required | API key required |
| Stealth mode | No | Yes |
| Proxy/CAPTCHA | No | Yes |
| Best for | Development | Production/scraping |
Best Practices
- Always navigate first before interacting
- View screenshots after each command to verify
- Be specific in action descriptions
- Close browser when done
Troubleshooting
- Chrome not found: Install Chrome or use Browserbase mode
- Action fails: Use
browser observeto discover available elements - Browserbase fails: Verify API key and project ID are set
