CaptchaFox

CaptchaFox is a German GDPR-compliant bot protection service from Scoria Labs GmbH that stops spam, fake signups, and fraud without the usability and privacy baggage of Google reCAPTCHA. The service uses adaptive detection with zero-friction challenges — no cookies, no tracking, no personal data stored on end users.

CaptchaFox was built with European compliance in mind from day one: it runs entirely on EU infrastructure and is a drop-in replacement for reCAPTCHA thanks to API compatibility. Swapping is usually a single-line change.

Key features:

• Adaptive bot detection — multiple security strategies combined for accurate scoring
• Zero-friction challenges — invisible or single-click, never image puzzles
• reCAPTCHA API compatibility — drop-in replacement with minimal code changes
• Accessibility-first — WCAG-compliant, screen reader friendly
• Multi-language — localised challenge types across major languages
• Pre-built SDKs — React, Vue, Angular, WordPress, Keycloak, vanilla JS
• Analytics dashboard — detailed insight into traffic, bots, and attack patterns

Defends against account takeover, fake accounts, scalping, carding, ad fraud, and spam. Operated and hosted in Germany — fully GDPR-compliant with no cookies or end-user PII.
