# The Anti-Scraper Ecosystem: A Comprehensive Survey of Open-Source Projects for Browser Stealth and Fingerprint Evasion > Source: > Published: 2026-06-11 00:00:00+00:00 This report catalogs and analyzes the complete landscape of open-source GitHub projects that provide anti-scraper detection, browser fingerprint evasion, and stealth web automation capabilities. The ecosystem spans **40+ distinct projects** across multiple categories: source-level browser patches (C++/Chromium/Firefox), JavaScript injection-based stealth plugins, protocol-level bypass libraries, HTTP client fingerprint spoofers, benchmark/test frameworks, AI-agent browser automation tools, and commercial anti-detect browsers with open-source SDKs. The field has evolved through three distinct waves. The first wave (2018–2020) was dominated by JavaScript-injection plugins like `puppeteer-extra-plugin-stealth` — simple but increasingly detectable as detection systems improved. The second wave (2020–2023) introduced source-level browser patches, including `undetected-chromedriver` , Camoufox (Firefox C++ patches), and the rebrowser patch ecosystem. The third wave (2023–present) has seen the rise of “CDP-minimal” frameworks like `nodriver` and `selenium-driverless` that bypass WebDriver entirely, direct-communication approaches, and AI-agent-integrated stealth browsers.
