C++ engine patches beat Cloudflare Turnstile where Puppeteer-stealth plugins fail.

Strengths
  • Patching 34 surfaces in C++ prevents JS-based detection from finding automation leaks.
  • Zero code changes required; existing Playwright scripts connect via standard CDP.
  • Monthly upstream rebases keep the stealth engine current against evolving detector logic.
Weaknesses
  • Compiling the engine from source requires significant bandwidth and build time.
  • Binary distribution trust is unclear without reproducible build verification guides.

Post Description

i personally believe that the internet is the best thing we've ever built, and arguably, nothing we made before comes close. now agents can use it too, but the web treats them as second-class. every agent works for a person, so whatever it keeps from agents it keeps from us. we believe that if we let them in, each of us gets the whole of what we built, a thousand times over.

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!
