Show HN: Fortress – open-source Chromium that keeps browser agents unblocked

Tags: chromium, browser-automation, anti-detection

Score: 7.3/10 (Innovation: 7, Technical: 9, Documentation: 8, Utility: 5)

Fortress is a stealth Chromium engine that patches browser fingerprinting at the C++ level to make automated browsers appear as human users, bypassing bot detectors like Cloudflare and Akamai. Its novel approach of modifying the engine internals rather than using JavaScript stealth patches makes detection significantly harder. The project shows strong technical depth with 34 in-tree patches and JA3/JA4 TLS coherence, but its utility is limited by niche anti-bot evasion use cases and legal/ethical considerations.

Target audience: backend devs, data engineers
