puppeteer-stealthvsprimp
Puppeteer Stealth is puppeteer plugin that fortifies headles browser for web scraping. This makes detection of puppeteer scrapers more difficult allowing to scrape targets which use headless browser detection techniques.
Puppeteer-stealth does this by applying various javascript patches to cover up traces of headless browser presence in the web scraping browser's environment.
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.
