Why CAPTCHA?

Protect signups, logins, and forms—without puzzles.

Reduce spam, stop fake accounts, and prevent account takeovers. Protect yourself and your website with our CAPTCHA.

Fake Signups & Bot Accounts

Stop automated registrations and bot-created accounts—without adding friction for real users.

Credential Stuffing & Brute Force

Protect login and password reset flows from large-scale attack attempts and automated takeovers.

Form & Comment Spam

Keep contact forms, newsletters, and comment sections clean by blocking spam before it reaches your team.

Checkout Abuse & Scraping

Reduce automated cart abuse, inventory attacks, and scraping that distort demand and hurt conversions.

API Abuse

Shield sensitive endpoints from automated misuse and high-volume calls—without breaking legitimate traffic.

Lower Support Load

Fewer false positives and smoother user flows mean fewer drop-offs—and fewer support tickets to handle.
