Captcha Solver

What is a Captcha Solver?

A captcha solver is a system or service that solves CAPTCHAs, allowing automated or manual access to websites and applications. Automated solvers use algorithms or AI to bypass challenges, while manual solvers rely on human workers. Captcha solvers are commonly used in bot-driven activities and can be part of larger operations like captcha farms.

Prosopo is committed to combating the misuse of captcha solvers by promoting privacy-first solutions that leverage smart, rule-based restrictions.

Captcha solvers and form spam

Most form spam isn't authored by humans — it comes from bots running cheap captcha solvers against any form they can find. If your site is filling up with junk submissions, fake signups or unwanted contact-form messages, a captcha solver is almost certainly the upstream cause. See our spam bot protection use case for how Procaptcha defeats solvers at the form level, and the Spam Filter for blocking the disposable inboxes and abusive networks they submit from.
