Quick Start

Complete Beginner Guide

Never set up a Raspberry Pi before? COMPLETE SETUP GUIDE - Step-by-step from zero to SaaS builder in 30 minutes!

Prerequisites

# Install system dependencies sudo apt update sudo apt install chromium-browser nodejs npm python3 # 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] The page displays a JSON object with a slideshow structure containing: - Author: "Yours Truly" - Date: "date of publication" - Title: "Sample Slide Show" ...

Usage Examples

Python API

import simple_browser # Navigate to any website result = simple_browser.browser_navigate("https://example.com") print(result) # "Successfully navigated to https://example.com" # Take a screenshot screenshot = simple_browser.browser_screenshot("homepage.png") print(screenshot) # "Screenshot saved to /tmp/homepage.png" # Execute JavaScript title = simple_browser.browser_evaluate("document.title") print(title) # Website title # Extract page content content = simple_browser.browser_get_content("text") print(content[:100]) # First 100 chars of page text

MCP Tools (via Claude Code)

Once configured, use these tools directly in Claude Code:

  • navigate - Go to URLs
  • screenshot - Capture page images
  • click - Click elements by CSS selector
  • fill - Fill form fields
  • evaluate - Execute JavaScript
  • get_content - Extract page HTML/text
  • close_browser - Clean shutdown

Real-World Use Cases

1. End-to-End SaaS Testing (The Game Changer)

# Complete user journey testing - NO HUMAN DEBUGGING NEEDED def test_saas_signup_flow(): # Navigate to signup page simple_browser.browser_navigate("https://yourapp.com/signup") # Fill registration form simple_browser.browser_fill("#email", "test@example.com") simple_browser.browser_fill("#password", "securepass123") simple_browser.browser_click("#signup-btn") # Verify successful signup success_msg = simple_browser.browser_evaluate("document.querySelector('.success-message').textContent") # Test dashboard access simple_browser.browser_navigate("https://yourapp.com/dashboard") dashboard_loaded = simple_browser.browser_evaluate("document.querySelector('.dashboard').style.display !== 'none'") # Take screenshot for visual regression simple_browser.browser_screenshot("dashboard_post_signup.png") return "PASS" if success_msg and dashboard_loaded else "FAIL"

2. Autonomous API + Frontend Testing

# Backend API validation through frontend def validate_api_through_ui(): # Test data creation via UI simple_browser.browser_navigate("https://yourapp.com/create-project") simple_browser.browser_fill("#project-name", "Test Project AI") simple_browser.browser_click("#create-btn") # Verify data appears in list view simple_browser.browser_navigate("https://yourapp.com/projects") project_exists = simple_browser.browser_evaluate("document.querySelector('[data-project=\"Test Project AI\"]') !== null") # 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

Architecture

🛠️ Technical Details

System Requirements

  • OS: Raspberry Pi OS (64-bit) or any ARM64 Linux
  • RAM: 4GB minimum, 8GB recommended
  • Storage: 32GB+ fast SD card (Class 10/A2)
  • Browser: Chromium (installed via apt)
  • Runtime: Node.js 18+, Python 3.8+

Browser Configuration

// Optimized for ARM64 { executablePath: '/usr/bin/chromium-browser', headless: true, args: [ '--no-sandbox', '--disable-setuid-sandbox', '--disable-dev-shm-usage', '--disable-gpu', '--disable-web-security', '--disable-features=VizDisplayCompositor' ] }

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'
