Could you build this?
No Developing an anti-detect stealth Chromium browser requires modifying Chromium C++ source code to defeat advanced browser fingerprinting, TLS/JA3/JA4 fingerprinting, and behavioral bot detection systems.
What it would actually take: The project requires custom Chromium C++ patches that tamper with WebGL renderer parameters, canvas readbacks, AudioContext fingerprinting, Navigator APIs, and CDP runtime flags without breaking legitimate web APIs. Additionally, it requires low-level TLS library modifications (BoringSSL) to mimic authentic browser client hellos (JA4/HTTP2 fingerprints) and continuous reverse-engineering against anti-bot vendors like Cloudflare and DataDome. This demands specialized offensive security, browser internals, and anti-bot reverse-engineering skills.
Discussion
20 comments analyzed.
Competitors mentioned: wget --mirror, Anubis
Concerns raised: Bot protection mechanisms block legitimate users and cause poor user experience, Abusive crawlers use residential proxies to evade detection, making mitigation difficult, Web scraping tools facilitate theft of intellectual property, Attestation systems risk turning into surveillance and control mechanisms, Difficulty distinguishing real pages from degraded or challenge pages in automation
Feature requests: Websites should offer standardized scrape-friendly data export (e.g., /scrape endpoint with monthly torrents), Better mechanisms to block bandwidth-hogging bots without blocking legitimate automated requests, Negative star rating option for GitHub repos
