curl-cffivscamoufox
Curl-cffi is a Python library for implementing curl-impersonate which is a
HTTP client that appears as one of popular web browsers like:
- Google Chrome
- Microsoft Edge
- Safari
- Firefox
Unlike requests and httpx which are native Python libraries, curl-cffi uses cURL and inherits it's powerful features
like extensive HTTP protocol support and detection patches for TLS and HTTP fingerprinting.
Using curl-cffi web scrapers can bypass TLS and HTTP fingerprinting.
Camoufox is an anti-detect browser built on Firefox, designed specifically for web scraping and browser automation while evading bot detection systems. Unlike Chrome-based anti-detect solutions, Camoufox uses a patched version of Firefox with over 100 modifications to prevent fingerprinting and detection.
Key features include:
- Firefox-based stealth Uses Firefox instead of Chrome, which has different fingerprinting characteristics and is less commonly targeted by anti-bot systems. The browser is patched at the C++ level to prevent JavaScript-based fingerprint leaks.
- Realistic fingerprints Generates and applies realistic browser fingerprints including screen resolution, WebGL renderer, fonts, and other browser properties that match real user configurations.
- Playwright integration Works seamlessly with Playwright for Python, providing the familiar Playwright API while running through the stealth-patched Firefox instance.
- Proxy support Built-in proxy support with authentication, including residential proxy rotation.
- Geolocation spoofing Can spoof browser geolocation to match proxy IP location for consistent fingerprints.
- Human-like behavior Includes utilities for adding human-like mouse movements and typing patterns.
Camoufox is particularly effective against sophisticated anti-bot systems that detect Chrome-based automation tools. By using Firefox as the base, it avoids many Chrome-specific detection vectors while the deep browser patches prevent general fingerprinting techniques.
