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!https://github.com/tiliondev/fortress

Could you build this?

No Providing unrestricted web access for autonomous agents requires building and maintaining an anti-bot evasion and scraping proxy platform at scale, constantly combating sophisticated bot detection systems.

What it would actually take: This system requires a fleet of headless browsers (e.g., custom Chromium forks with patched CDP/WebRTC leaks), residential proxy rotators, and automated CAPTCHA solving pipelines. It requires continuous reverse-engineering of Cloudflare, Akamai, and DataDome fingerprinting techniques, alongside substantial distributed cloud infrastructure.

Discussion

3 comments analyzed.

Concerns raised: Risk of blocking by major platforms like Cloudflare if tool becomes popular, Data center IP detection triggers before browser fingerprint checking, WebRTC leakage exposes real IP despite fingerprint spoofing, TCP/IP stack fingerprints (TTL, window size) reveal actual OS layer

Feature requests: Handle WebRTC IP leakage at network layer, Spoof TCP/IP protocol stack fingerprints, Residential IP rotation or masking capabilities
