How it started

We needed web scraping. Simple enough, right? Just grab Selenium and go.

Except reality had other plans: CloudFlare blocked us within seconds, Chrome couldn't handle SOCKS5 proxies with authentication, and running multiple processes caused them to crash each other.

We found undetected-chromedriver — it bypassed bot detection, which was exactly what we needed. But the maintainer had abandoned it, and it was broken in all the places that mattered to us.

So we decided: let's fork it and fix it ourselves.

What we added
