# Verify Chromium works
chromium-browser --version
Installation
git clone https://github.com/nfodor/claude-arm64-browser
cd claude-arm64-browser
npm install
chmod +x *.py *.sh
Quick Test (One-Liner)
# Verify it works immediately after install:
python3 -c "import sys; sys.path.append('.'); import arm64_browser; print('[OK] ARM64 Browser Works!' if 'error' not in arm64_browser.navigate('https://example.com').lower() else '[FAIL] Failed')"
Expected Result: [OK] ARM64 Browser Works!
>>> Run the Kick-Ass Demo
# Quick demo with immediate visible results (30 seconds)
python3 instant_demo.py
# Or comprehensive demo showing all capabilities (2-3 minutes)
./run_demo.sh
Test the Setup
# Test MCP server directly
echo '{"jsonrpc":"2.0","method":"tools/list","id":1}' | node index.js
# Test Python wrapper
python3 simple_browser.py
Claude CLI Integration
Prerequisites
# Install Claude CLI if you haven't already
npm install -g @anthropic/claude-cli
Add to Claude CLI
# From the project directory after cloning
claude mcp add chromium-arm64 "$(pwd)/mcp-wrapper.sh" --scope user
Verify Connection
claude mcp list
# Should show: chromium-arm64: /path/to/mcp-wrapper.sh - ✓ Connected
⚠️ Important: Restart Claude After Adding
You MUST start a new Claude session after adding the MCP server:
# Exit current session if in one
exit
# Start fresh session
claude
Using in Claude CLI
Ask Claude to use the chromium-arm64 tools:
List available MCP servers and use chromium-arm64 to navigate to https://example.com
Take a screenshot using the chromium-arm64 tool
Use chromium-arm64 to click the button with selector #submit
Fill the email field using chromium-arm64 with test@example.com
Be explicit to avoid Playwright/Puppeteer:
- "Use chromium-arm64 to navigate..."
- "Using the chromium-arm64 tool, take a screenshot"
- "Open a browser" (might try broken Playwright)
- "Take a screenshot" (might try broken Puppeteer)
Success Example
When working correctly, you'll see:
You: Use chromium-arm64 to navigate to https://httpbin.org/json and show me what you see
Claude: I'll navigate to https://httpbin.org/json using the chromium-arm64 tool.
[Uses chromium-arm64.navigate tool]

# Test data modification
simple_browser.browser_click("[data-project=\"Test Project AI\"] .edit-btn")
simple_browser.browser_fill("#project-name", "Modified by AI")
simple_browser.browser_click("#save-btn")
# Verify backend persistence
simple_browser.browser_navigate("https://yourapp.com/projects")
updated = simple_browser.browser_evaluate("document.querySelector('[data-project=\"Modified by AI\"]') !== null")
return {"api_create": project_exists, "api_update": updated}
3. Cross-Browser Compatibility (Zero Human Intervention)
# Automated cross-platform testing
def test_responsive_design():
test_results = {}
# Mobile viewport
simple_browser.browser_evaluate("window.resizeTo(375, 667)") # iPhone size
simple_browser.browser_navigate("https://yourapp.com")
simple_browser.browser_screenshot("mobile_view.png")
mobile_nav = simple_browser.browser_evaluate("document.querySelector('.mobile-nav').style.display !== 'none'")
# Desktop viewport
simple_browser.browser_evaluate("window.resizeTo(1920, 1080)")
simple_browser.browser_screenshot("desktop_view.png")
desktop_nav = simple_browser.browser_evaluate("document.querySelector('.desktop-nav').style.display !== 'none'")
return {"mobile_responsive": mobile_nav, "desktop_responsive": desktop_nav}
4. Competitive Analysis Automation
# Monitor competitor pricing
simple_browser.browser_navigate("https://competitor.com/pricing")
simple_browser.browser_screenshot("competitor_pricing.png")
prices = simple_browser.browser_evaluate("document.querySelectorAll('.price').length")
5. SEO Monitoring
# Check search rankings
simple_browser.browser_navigate("https://google.com/search?q=your+keywords")
simple_browser.browser_screenshot("serp_results.png")
rankings = simple_browser.browser_evaluate("document.querySelector('.g').textContent")
Why ARM64 + Browser Automation = SaaS Gold
The Critical Gap in SaaS Development
Every SaaS startup MUST ensure their application works end-to-end before shipping. Traditional approaches fail because:
- ** Manual Testing**: Expensive, slow, error-prone, doesn't scale
- ** x86_64 Only Tools**: Puppeteer/Playwright fail on ARM64 with broken binaries
- ** Human Debugging**: QA teams spend days debugging test failures
- ** Limited Coverage**: Can't test every user journey without massive teams
- ** Regression Blind Spots**: Changes break existing features without detection
Our Breakthrough: Autonomous AI Testing on ARM64
- Zero Human Debugging: AI agents test complete user flows autonomously
- 24/7 Continuous Testing: Always-on validation on budget hardware
- Full Stack Coverage: Frontend + Backend + API validation through real browser
- Visual Regression Detection: Screenshots catch UI breaking changes automatically
- Cross-Device Testing: Mobile/tablet/desktop viewport automation
- Native ARM64: Uses system Chromium instead of broken x86_64 binaries
- Cost Effective: $480 setup vs $50K+ traditional QA infrastructure
Why This Changes SaaS Development Forever
Before: Manual QA teams → Expensive → Slow → Human errors → Limited coverage
Deploy → Hope → Customer finds bugs → Emergency fixes → Reputation damage
After: AI agents → Autonomous → Fast → Comprehensive → 24/7 monitoring
Code → AI tests everything → Deploy with confidence → Happy customers
The ARM64 Advantage
Standard browser automation fails on ARM64 because Puppeteer/Playwright download x86_64 binaries that don't run. Our solution:
- Uses system-installed Chromium (native ARM64)
- Proper launch flags for headless ARM64 operation
- MCP protocol compliance for Claude Code integration
- Zero dependency on pre-built browser binaries

Troubleshooting
MCP Connection Issues
chromium-arm64 shows "✗ Failed to connect"
# Check if the wrapper script exists and is executable
ls -la $(pwd)/mcp-wrapper.sh
chmod +x mcp-wrapper.sh
# Test the server directly
echo '{"jsonrpc":"2.0","method":"tools/list","id":1}' | node index.js
# Re-add with correct path
claude mcp remove chromium-arm64
claude mcp add chromium-arm64 "$(pwd)/mcp-wrapper.sh" --scope user
# IMPORTANT: Restart Claude
exit
claude
Claude tries to use Playwright/Puppeteer instead
- Be explicit: Always mention "chromium-arm64" in your prompts
- Check available servers:
claude mcp list - If chromium-arm64 isn't listed, restart Claude
"Server not found" in Claude session
- MCP servers are loaded at startup
- Always restart Claude after adding/modifying MCP servers
- Run
claude mcp list to verify before starting
Common Issues
Browser won't start
# Check Chromium installation
which chromium-browser
chromium-browser --version
# Test headless mode
chromium-browser --headless --disable-gpu --dump-dom https://example.com
MCP connection fails
# Verify Claude Code MCP setup
claude mcp list
# Test server manually
echo '{"jsonrpc":"2.0","method":"tools/list","id":1}' | node index.js
Memory issues
# Monitor system resources
htop
# Optimize Chromium memory usage
# Add to browser args: '--memory-pressure-off', '--max_old_space_size=512'
