CAPTCHAs are a popular and effective method for preventing bots from submitting spam to your forms.
hCaptcha is a free, privacy-friendly, alternative to Google's reCAPTCHA.
hCaptcha is our recommended CAPTCHA solution for customers with strict privacy commitments or who need to serve some regions, such as China, where Google's services are intermittently blocked.
Formspark's free integration with hCaptcha takes seconds to set up.
