Browser Automation with OpenClaw

OpenClaw provides powerful browser automation capabilities through its browser tool, enabling AI agents to interact with web pages just like a human would. This guide covers the core concepts, setup, and practical usage patterns for effective automation.

What Is Browser Automation in OpenClaw?

The browser tool allows AI agents to control a dedicated, isolated Chromium-based browser instance. It supports essential actions such as:

• Navigating to URLs
• Taking screenshots and full-page captures
• Analyzing page structure through snapshots (accessibility tree)
• Interacting with elements (clicking, typing, filling forms)
• Managing tabs and browser state
• Handling downloads and file uploads

This creates a secure, deterministic environment for agents to perform web-based tasks without interfering with your personal browsing.

Key Profiles: openclaw vs chrome

OpenClaw supports two primary browser control modes:

openclaw (Managed Browser)

• Runs a dedicated, isolated browser instance
• Uses its own user data directory, completely separate from your personal browser
• Controlled directly by OpenClaw through CDP (Chrome DevTools Protocol)
• Ideal for automated workflows and testing

chrome (Extension Relay)

• Controls your existing Chrome tabs via a browser extension
• Requires manual attachment by clicking the OpenClaw Browser Relay extension
• Useful for controlling specific tabs in your active browser

For most automation scenarios, the openclaw profile is recommended for its isolation and reliability.

Getting Started

Prerequisites

• Make sure the browser is enabled in your OpenClaw configuration
• Ensure Playwright is installed for advanced features (snapshots, actions)

Basic Commands

# Check browser status
openclaw browser --browser-profile openclaw status

# Start the managed browser
openclaw browser --browser-profile openclaw start

# Open a URL
openclaw browser --browser-profile openclaw open https://example.com

# Take a screenshot
openclaw browser --browser-profile openclaw screenshot

Snapshot and Interaction Workflow

The core automation pattern follows three steps:

1. Snapshot: Capture the current page structure
2. Analyze: Identify the elements you want to interact with
3. Act: Perform actions on those elements

# Capture an interactive snapshot with element references
openclaw browser snapshot --interactive

# Click on element with reference e12
openclaw browser click e12

# Type text into a form field
openclaw browser type e23 "Hello World" --submit

Practical Use Cases

Web Research Automation

Automate the process of gathering information from multiple web sources:

1. Navigate to a search results page
2. Extract links from the page
3. Visit each link and summarize the content
4. Compile findings into a report

Form Automation

Fill out and submit web forms programmatically:

• Pre-fill contact information
• Upload documents
• Submit applications
• Handle multi-step forms

Testing and Verification

Use browser automation to:

• Verify web application functionality
• Check for broken links
• Monitor page load performance
• Validate content updates

Best Practices

Use Interactive Snapshots

Always use --interactive when you need to perform actions:

openclaw browser snapshot --interactive

This provides clear element references (e.g., e12, e23) that you can use in subsequent actions.

Handle Dynamic Content

Web pages often load content asynchronously. Use wait commands to ensure elements are ready:

# Wait for an element to appear
openclaw browser wait "#main-content"

# Wait for URL to change
openclaw browser wait --url "**/dashboard"

# Wait for JavaScript condition
openclaw browser wait --fn "window.ready === true"

Manage Browser State

Maintain clean state between automation runs:

# Clear cookies
openclaw browser cookies clear

# Clear local storage
openclaw browser storage local clear

# Close all tabs
openclaw browser tabs | jq -r '.targets[] | .targetId' | xargs -I {} openclaw browser close {}

Security Considerations

• The managed browser profile may contain sensitive data; treat it as confidential
• Limit execution of arbitrary JavaScript via evaluate commands
• Keep the Gateway service on a private network
• Use environment variables for sensitive configuration

Troubleshooting

Common Issues

Browser won't start: Ensure no other Chrome instances are using the same CDP port (default 18800)

Elements not found: Take a new snapshot after page navigation, as references are not stable across page loads

Playwright errors: Install Playwright if advanced features are not working:

npm install playwright

Advanced Features

Headless Mode

Run automation without displaying the browser window:

{
  "browser": {
    "headless": true
  }
}

Custom Browser

Specify a different Chromium-based browser (Brave, Edge, etc.) in configuration:

{
  "browser": {
    "executablePath": "/Applications/Brave Browser.app/Contents/MacOS/Brave Browser"
  }
}

Remote Control

Control browsers on remote machines through node hosts or Browserless.io endpoints for distributed automation.

Browser automation in OpenClaw transforms AI agents from passive information processors into active web operatives, capable of performing complex, multi-step tasks across the internet. By following these patterns and best practices, you can build reliable, maintainable automation workflows that extend your agent's capabilities far beyond simple API calls.
