🔧 Technical Details

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'
