CloakBrowser

CloakBrowser is a custom-built Chromium browser designed for developers and automation tasks, with a focus on evading bot detection systems by modifying browser fingerprints at the C++ source level. Unlike tools that rely on patched configurations or JavaScript injection, it delivers a genuine Chromium binary where attributes such as canvas, WebGL, audio, fonts, GPU, and hardware reporting are altered directly in the browser’s source code. This approach ensures that antibot systems score it as a normal browser, providing consistent and reproducible automation behavior.

The tool serves as a drop-in replacement for Playwright and Puppeteer in both Python and JavaScript environments, maintaining the same API and code structure. Migration requires only a change in the import statement, with no new abstractions or SDKs to learn. CloakBrowser is compatible with Playwright, Puppeteer, and Selenium, and is used by AI browser agents. It supports human-like interaction through a 'humanize=True' flag, which adds Bézier mouse movements, natural keyboard timing with pauses, and realistic scroll physics for testing user flows. The browser also manages persistent profiles, auto-detects GeoIP timezone, locale, and language from proxy IPs, and includes a binary management CLI for deployment at scale.

CloakBrowser is available on Linux x64, Linux ARM64, Windows x64, and macOS platforms. Installation is supported via pip, npm, and Docker, with the browser binary auto-downloading for the user’s platform. The tool does not include CAPTCHA-solving services or built-in proxy rotation; users can bring their own proxies and continue using the Playwright API as usual. Test results show that CloakBrowser passes detection on over 30 sites, outperforming stock Playwright in avoiding bot detection by services such as reCAPTCHA v3, Cloudflare Turnstile, and FingerprintJS.

Pricing is offered in three plans: Solo at $19 per month for 3 active browser sessions, Team at $49 per month for 20 sessions, and Business at $199 per month for 200 sessions. All plans include the latest Chromium binary, compatibility improvements, support for Linux, Windows, and macOS, and a 7-day free trial. Hands-on support is also provided with each plan.
