Fortress
TLDR Dev
Fortress is a Chromium fork that modifies browser fingerprinting at the C++ engine level rather than through JavaScript patches, allowing automated tools to pass bot detection systems like Cloudflare Turnstile and Sannysoft. The engine patches 34 single-purpose C++ modifications and ships as version 151.0.7908.0 with support for Playwright and Puppeteer over the Chrome DevTools Protocol on port 9222. Users can install it via pip, npm, or Docker and point existing browser automation code at it without changes, with the ability to customize persona details like timezone and hardware specifications through command-line flags.
Why it matters
Fortress is a stealth Chromium engine designed to prevent scrapers and browser agents from being blocked by correcting the browser fingerprint within the engine itself. By modifying over thirty surfaces that bot detectors monitor, Fortress allows automation tools like Playwright and Puppeteer to operate without changes to existing code.
