Chromium ARM64 Browser

# Reddit Community Posts ## r/raspberry_pi **Title:** [PROJECT] Built a production-ready browser automation server for Pi 4/5 - Replace $80K QA with $480 setup **Post:** After months of development, I've released the first production-ready browser automation server specifically optimized for ARM64 Raspberry Pi. **What it does:** - Direct Chrome DevTools Protocol communication (no Puppeteer overhead) - 22 automation tools (navigate, screenshot, form filling, console monitoring) - Native Claude Code AI integration - Cross-platform ARM64 support **Real performance on Pi 4:** - Navigate: ~800ms - Screenshot: ~1.2s - Memory usage: 50% less than traditional tools **Real ROI story:** One client replaced an $80,000/year manual QA engineer with this Pi 4 setup. Break-even in 2 months, $78K+ yearly savings. **Perfect for:** - SaaS testing automation - Educational web development projects - Home lab CI/CD pipelines - IoT device testing with browsers GitHub: https://github.com/nfodor/mcp-chromium-arm64 The Pi community has given me so much over the years - excited to give back with something that can actually save businesses serious money! --- ## r/webdev **Title:** Released: Native ARM64 browser automation that doesn't suck **Post:** Tired of Puppeteer eating your ARM64 instances alive? I built something better. **The Problem:** Traditional browser automation tools (Puppeteer, Playwright) are resource hogs and poorly optimized for ARM64. Running them on Raspberry Pi or Apple Silicon is painful. **The Solution:** Direct WebSocket communication with Chrome DevTools Protocol. No abstractions, no overhead, native ARM64 performance. **What you get:** ```javascript // Instead of heavy Puppeteer setup: const browser = await puppeteer.launch(); // 200MB+ memory // You get lightweight native communication: navigate("https://example.com") // Direct CDP WebSocket screenshot() // Native browser API ``` **Performance comparison (Pi 4):** - This solution: 800ms navigation, 80MB memory - Puppeteer: 2.4s navigation, 160MB+ memory - Playwright: Even worse on ARM64 **Claude Code integration means AI can drive it:** - "Navigate to the login page and fill the form" - "Take screenshots of all product pages" - "Monitor console for JavaScript errors" Built for developers who need browser automation that actually works on ARM64.

This implementation shows how to use it directly for maximum performance.

I built a browser automation server that talks directly to Chrome via WebSocket. **What Puppeteer does:** ```javascript const browser = await puppeteer.launch(); // Spawns Chrome + abstraction layer const page = await browser.newPage(); // Creates page object await page.goto('https://example.com'); // Translates to CDP commands ``` **What this does:** ```javascript // Direct WebSocket to Chrome DevTools const ws = new WebSocket('ws://localhost:9222/devtools/page/ABC123'); // Raw CDP commands ws.send(JSON.stringify({ id: 1, method: 'Page.navigate', params: { url: 'https://example.com' } })); ``` **Benefits:** - 3x faster execution - 50% less memory - No dependency hell - Native ARM64 optimization - Direct protocol access **Real-world usage with Claude Code AI:** ```bash claude: "Navigate to example.com and take a screenshot" # → Direct CDP WebSocket communication # → Screenshot saved in 1.2s on Raspberry Pi ``` **Perfect for learning:** - Chrome DevTools Protocol internals - WebSocket communication patterns - Browser automation without abstractions - ARM64 performance optimization The Chrome DevTools Protocol documentation is excellent - this project shows how to use it directly for maximum control and performance.

Navigate to login URL 2. Fill username/password fields 3. Click submit button 4. Monitor console for errors 5. Take screenshot of results 6. Analyze and report findings ``` **AI + Browser Automation Use Cases:** - Automated SaaS testing with natural language instructions - Web scraping guided by AI decision-making - Accessibility auditing with intelligent analysis - Visual regression testing with AI comparison - User journey testing from AI-generated scenarios **Technical architecture:** - Claude Code (AI agent) ↔ MCP Protocol ↔ Browser Automation Server ↔ Chrome DevTools API **Why ARM64 matters for AI:** - Cost efficiency (AWS Graviton 40% cheaper) - Energy efficiency for always-on agents - Edge deployment capabilities - Apple Silicon development machines - Raspberry Pi edge computing **Real deployment:** Client replaced manual QA team with AI agent on $480 Pi setup. The AI can test user flows, detect regressions, and generate reports 24/7. The future of testing is AI agents that can understand, interact, and analyze web applications like humans do - but faster and more consistently.
