Fortress – open-source Chromium that keeps browser agents unblocked
C++ Chromium patches beat JS-level stealth plugins like puppeteer-extra-plugin-stealth.
Stealth Chromium engine that stops scrapers and browser agents from getting blocked, with one line of code change.

and to add to that, democratization of tools that allow this is essential, despite the fact that there will always be bad actors.
so, we built fortress, which is an open-source stealth chromium engine. it is a recompiled fork that corrects the browser fingerprint from inside the engine: the surfaces bot detectors read, canvas, webgl, audio, fonts, navigator, and about thirty more, are patched in chromium's c++, with no javascript layer sitting on top for a page to catch.
it beats the hardest bot detectors on the planet, works fully locally and is open source for y'all to see the patches we've made. and it comes with an mcp, so you can use it with your agents without having to do any major setup or code changes. do give it a try here!
