Best Python Libraries for Cloudflare Bypassing in 2026?

Hey everyone,
I am building a custom scraper for a real estate directory, but their Cloudflare protection is giving me a headache.
Standard Selenium with undetected-chromedriver is getting blocked after a few hundred requests, even with premium residential proxies.
Are you guys having better success with Playwright, or should I switch to a request-based scraper using scrapfly/zenrows APIs?
Appreciate any insights from veterans who deal with heavy scraping daily.

My business involves heavy daily web scraping. The best solutions right now are nodriver and zendriver. They have no issue with scraping FB Marketplace on just a few dozen residential proxies. Nodriver/zendriver gets through cloudflare turnstile (the "are you human?" checkbox) very easily, but you would still need a captcha solver if the site presents one to you.

If those libraries don't work for you, double check that your proxies are being rotated correctly in your app code. It's best to use a forward proxy like squid that can round robin your requests evenly across your proxies. That way your app just connects to the proxy and doesn't have to manage any connection-related state. You can also filter out images and CSS at the proxy-level and that cut save you 90% on bandwidth.

Try async playwright with the webkit browser

What about playwright? you should also avoid running in headless mode

I’d probably test Playwright first before moving fully to a scraping API. It gives you more control over how the pages are loaded, especially if the site depends heavily on JavaScript.

Scrapfly or ZenRows are also worth testing if you don’t want to maintain all the browser infrastructure yourself. I’d run a small comparison on the same batch of pages and look at success rate, speed, cost, and how much maintenance each option needs. I wouldn’t rely on proxies alone, though. Things like caching, avoiding duplicate requests, reasonable request pacing, and only loading the data you actually need can make a pretty big difference.
