Proxies vs Captcha

IP reputation is just one factor. Browser fingerprint and how you use the proxy can also make a big difference in triggering CAPTCHAs.

They can be related but it’s not a simple inverse relationship.

Good-quality proxies may reduce some CAPTCHA triggers but IP reputation, request volume, behavior and browser signals also matter.

I’d focus on using a smaller pool of reputable proxies rather than just buying more.

Usually, proxy quality and proper request patterns matter more than quantity.

I don't think its that simple. Good proxies can help but you can still get captchas if the website doesn't like the requests or your behaviour looks unusual.

If I had to spend money on one thing first I would probably test better proxies and see how much the captcha rate goes down. No point buying tons of proxies if the same problem is still there

Not exactly, but better proxies usually mean fewer CAPTCHAs. A clean IP helps, but sites also look at request rate, cookies, browser fingerprint, session behavior and whether the IP location matches everything else. Even a good proxy will trigger CAPTCHAs if you hit the site too aggressively.
Usually it’s cheaper to improve the proxy setup and request behavior first, then use CAPTCHA solving only as a fallback
