Body: Every web scraper hits the same wall: Cloudflare. You rotate IPs. You spoof headers. You use Playwright's stealth plugin. And Cloudflare still blocks you — because it checks things no JavaScript library can fake: WebGL renderer fingerprint, font enumeration, audio context, hardware concurrency, Canvas2D image data, WebRTC local IPs, and more. BrowserHand takes a different approach — C++ hooks at the Chromium binary level. Instead of patching JavaScript objects at runtime (which Cloudflare can detect), we patched the browser engine itself. 49 hooks across 12 subsystems: GPU: Forced WebGL vendor/renderer strings at the driver layer Fonts: Controlled which system fonts the browser exposes Audio: Faked audio context fingerprint at the OS level Network: Spoofed WebRTC IPs before the JS runtime could read them Canvas: Injected noise into Canvas2D/SVG fingerprinting reads Timing: Normalized JS timer precision to match real hardware profiles The result: same browser, same IP, same everything — but the…
