Primp is a Python HTTP client that impersonates real web browsers by replicating their TLS fingerprints, HTTP/2 settings, and header ordering. It is a lightweight alternative to curl-cffi for bypassing TLS and HTTP fingerprinting-based bot detection.
Key features include:
- Browser impersonation Can impersonate Chrome, Firefox, Safari, Edge, and OkHttp clients by replicating their exact TLS fingerprints (JA3/JA4), HTTP/2 frame settings, header ordering, and other connection-level characteristics.
- HTTP/2 support Full HTTP/2 support with configurable settings that match real browser behavior.
- Lightweight Smaller and simpler than curl-cffi while providing similar impersonation capabilities. Built on Rust for performance.
- Familiar API Provides a requests-like API with Session support, making it easy to adopt for developers familiar with the Python requests library.
- Proxy support HTTP and SOCKS5 proxy support with authentication.
- Cookie management Automatic cookie handling across requests within a session.
Primp fills a similar niche to curl-cffi and hrequests — HTTP clients designed to avoid TLS/HTTP fingerprinting — but takes a Rust-powered approach for better performance. It is particularly useful when you need to bypass bot detection that relies on connection-level fingerprinting without using a full browser.
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.
