Overview

CloakBrowser is a modified Chromium build engineered to defeat bot detection. Unlike traditional stealth plugins that patch fingerprints at the JavaScript layer, CloakBrowser patches the browser source code itself, so every fingerprint surface — canvas, WebGL, fonts, audio, navigator, and more — is consistent and undetectable. It is a drop-in replacement for Playwright: point your existing automation scripts at CloakBrowser and get 30/30 bot detection test passes out of the box. Ideal for AI agents, web scraping, ad verification, and any workflow that requires reliable, undetected browser automation. MIT licensed with an official Docker image (114K+ pulls) for quick deployment.
