How to bypass cloudflare when scraping a website?

@agshin rotating every single request is usually not the magic fix, it can actually look more weird if your cookies/session keep jumping IPs. For registration flows you normally want one clean IP + one browser profile per attempt, then rotate after the flow is done, not mid-way. If the site has proper CF + Turnstile, cheap DC proxies are basically a waste now... better to first confirm if it’s IP reputation or fingerprint/session issue before buying a bunch of resi traffic.

Skip Selenium for this, it's been fingerprinted to death. Use curl-cffi or tls-client in Python — they spoof the TLS handshake to match real Chrome, which is what CF's bot challenge actually checks. Pair with residential proxies (IPRoyal or BrightData sticky for 10min sessions) and you'll get through most CF setups without any browser at all. If the endpoint has the full JS challenge, FlareSolverr in front handles it.

This is interesting, I'll have to check that out.

It sounds like there's no workaround for rotating solid residential proxies.

I use this: https://github.com/sarperavci/CloudflareBypassForScraping

get cookies cf_clearance then crawler, if block change ip and get cf_clearance and crawler again. you can search Cloudflare Bypass for find more github respo

As title says.

I wanted to register my bot but the requirements for it are kinda crazy

Any other ways?

Rotating standard residential proxies fails because major residential providers rent out cheap, shared IP pools that are heavily flagged. Cloudflare tests the browser’s behavioral layer and the TLS handshake. If your proxy setup modifies headers or uses data center middle boxes that break the TLS chain, Cloudflare blocks it before your script even executes.

You need physical hardware endpoints on mobile networks to pass high security WAF checks.

Proxy is only one piece, and sometimes not even the main one. CF will still see weird browser state, timing, repeated form patterns, bad TLS, etc. If it’s a legit bot you’re trying to register, API/whitelist route saves way more time than playing cat and mouse... otherwise you’ll just keep buying “better” proxies and still get stuck.

Cloudflare is designed to protect websites from unauthorized scraping. If you need data, it's best to use the website's API, request permission, or follow their robots.txt and terms of service.
