Cloudscraper

A simple Python module to bypass Cloudflare's anti-bot page (also known as "I'm Under Attack Mode", or IUAM), implemented with Requests. Cloudflare changes their techniques periodically, so I will update this repo frequently.

This can be useful if you wish to scrape or crawl a website protected with Cloudflare. Cloudflare's anti-bot page currently just checks if the client supports Javascript, though they may add additional techniques in the future.

Due to Cloudflare continually changing and hardening their protection page, cloudscraper requires a JavaScript Engine/interpreter to solve Javascript challenges. This allows the script to easily impersonate a regular web browser without explicitly deobfuscating and parsing Cloudflare's Javascript.

For reference, this is the default message Cloudflare uses for these sorts of pages:

Checking your browser before accessing website.com.

This process is automatic. Your browser will redirect to your requested content shortly.

Please allow up to 5 seconds...

Any script using cloudscraper will sleep for ~5 seconds for the first visit to any site with Cloudflare anti-bots enabled, though no delay will occur after the first request.

Cloudscraper has an integrated automatic bypass captcha system 2captcha.com
