Damru – Android-in-Docker Browser Automation Framework (Zero JS Injection)

I built Damru because I kept seeing posts recommending Android Playwright CDP for scraping, but there was never a proper framework around it. So I made one.

This is strictly for educational purposes only. Do not use it for anything illegal or abusive.

What is Damru?

Damru is a browser automation framework built around real Android environments running in Docker. It's designed for scraping and automation tasks where mobile behavior actually matters — not just viewport resizing, but a genuine Android stack.

How is it different from Playwright, puppeteer-stealth, undetected-chromedriver, Camoufox, or Fingerprinting Chromium?

Most stealth tools fake mobile behavior on desktop Chrome using JavaScript injection (e.g. Object.defineProperty patches). Damru takes a completely different approach:

• Zero JS injection — spoofing is handled at the OS, binary, and CDP levels, not through brittle browser-side JS patches
• Real Android OS via Redroid — it's not desktop Chrome pretending to be mobile through viewport tricks
• Native mobile fingerprinting controls — device profiles, hardware overrides, locale/timezone matching, mobile network emulation, WebRTC/IPv6 blocking
• Multi-instance pooling — built for scaling across multiple containers
• Pre-baked image support — reduces setup overhead significantly
  • Feature List
    
    • Android-in-Docker via Redroid
    • Playwright support
    • Built-in database of 32+ Android device profiles
    • Proxy-aware timezone, locale, and language matching
    • Hardware overrides for CPU, RAM, and touch points
    • Mobile network emulation
    • WebRTC and IPv6 leak blocking
    • Native Android iptables-based network protections
    • Multi-container pooling for scale
    • Pre-baked image support to reduce setup time
    • TLS spoofing and more
      • Detection Resistance
        
        Damru is significantly stronger against detection systems like CreepJS, BrowserScan, Sannysoft, and Cloudflare Turnstile compared to standard Playwright or typical stealth plugins — primarily due to the deeper Android-based approach rather than surface-level JS patches.
        
        Pros and Cons
        
        Pros:
        • Highly undetectable due to real Android environment
        • No JS injection means fewer detection vectors
        • Scales well with multi-container pooling
          • Cons:
            • Slightly slower than desktop-based tools (real Android OS overhead)
            • Harder to set up — mitigated by the custom pre-baked Docker image included
              • Repo

                Would love feedback from anyone working on scraping, browser automation, or anti-bot research. Open to PRs, issues, and discussion!
