FAQ

Frequently asked questions

What is an invisible CAPTCHA?

An invisible CAPTCHA evaluates an interaction in the background without displaying a checkbox. If the interaction meets challenge criteria, a visual challenge may still appear. In hCaptcha Pro, invisible appearance and 99.9% Passive behavior can be combined for a low-friction experience. Set up Invisible mode.

What is the difference between invisible mode and 99.9% Passive mode?

Invisible mode removes the checkbox. 99.9% Passive mode determines how often real users receive a challenge based on an evaluation of thousands of factors. You can enable both settings to keep most verification in the background.

How does hCaptcha Pro differ from hCaptcha Free?

Pro adds a low-friction, self-optimizing challenge mode and custom themes. Free provides a classic CAPTCHA experience in which most users will generally see a challenge.

How does hCaptcha Pro differ from Enterprise?

Enterprise is a complete anti-abuse and bot mitigation platform. It adds capabilities such as passive No-CAPTCHA modes, risk scores, custom threat models, rich analytics, role-based access controls, SAML SSO, and strong SLAs.

When should I choose Pro instead of Enterprise?

Choose Pro for low-friction bot protection that you can enable in minutes. Choose Enterprise when you need defenses against account takeover, advanced persistent threats, or API abuse, or when committed volume pricing above 100,000 monthly evaluations is a better fit.

How is hCaptcha Pro billed?

The base subscription includes 100,000 evaluations per month. Annual billing is equivalent to $99 per month, while month-to-month billing is $139. Additional evaluations cost $0.99 per 1,000 requests and are charged periodically after the included quota is used.
