What is hCaptcha?

hCaptcha helps your favorite web services keep out bots, spam, and abuse by asking simple questions that are easy for humans and difficult for machines.

A service you use has chosen to improve your experience on their site by installing hCaptcha to reduce malicious traffic.

Why hCaptcha?

Each time you answer a challenge, we use sophisticated models to figure out whether you are human or a machine. The website you visited then uses this result to help improve your experience on their site by keeping out bots.

Privacy Focused

Ad networks see you as their product. They don’t. They do not care who users are, only how likely they are to be malicious. We support initiatives like Privacy Pass, and work hard to balance privacy and security.

Security First

hCaptcha is publisher-focused. They work to give sites real data and let them decide how to use it. Accuracy is in your interest and ours. Other captchas are provided by advertising companies. Every bot they block may reduce their revenue.
