Puppeteer-extra is a modular plugin framework that wraps Puppeteer (and Playwright) to add extra functionality through a plugin system. It acts as a drop-in replacement for Puppeteer while enabling powerful extensions for stealth, captcha solving, ad blocking, and more.
The most popular plugins include:
- puppeteer-extra-plugin-stealth Applies various evasion techniques to make the automated browser harder to detect. Patches common detection vectors like navigator.webdriver, Chrome.runtime, WebGL renderer strings, and more. This is the most widely used Puppeteer stealth solution.
- puppeteer-extra-plugin-recaptcha Automatically detects and solves reCAPTCHA and hCaptcha challenges using third-party solving services (2captcha, anti-captcha).
- puppeteer-extra-plugin-adblocker Blocks ads and trackers to speed up page loading and reduce bandwidth usage during scraping.
- puppeteer-extra-plugin-anonymize-ua Randomizes the User-Agent string to avoid fingerprinting.
Key features of the framework:
- Drop-in replacement
Use
puppeteer-extrainstead ofpuppeteerin your imports - existing code works without changes. - Plugin composition Multiple plugins can be stacked and they work together without conflicts.
- Playwright support
The same plugin system works with Playwright via
playwright-extra. - Community plugins Active community creating and maintaining plugins for various use cases.
Puppeteer-extra is the go-to solution for adding stealth capabilities to Puppeteer-based scrapers without rewriting existing code.
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.
