Block bots without annoying real users with this privacy-focused CAPTCHA alternative that works invisibly in the background. Unlike traditional CAPTCHAs that force users to solve puzzles, Private Captcha uses cryptographic challenges that are completely transparent to humans.

Key advantages over traditional solutions:

  • No user interaction required - visitors never see puzzles or challenges
  • GDPR/CCPA compliant by design - zero personal data collection
  • No cookies needed - eliminates intrusive consent banners
  • AI-resistant protection - cryptographic security unaffected by advancing bot intelligence
  • Accessibility-first - WCAG 2.2 compliant, screen reader friendly

Technical benefits include:

  • Lightweight integration - 93% smaller than Google reCAPTCHA
  • Smart difficulty scaling - automatically adjusts challenge complexity based on bot activity
  • EU-only infrastructure - all servers and suppliers based in Europe
  • Self-hosting option - deploy on your own infrastructure for maximum control

The service offers transparent pricing starting at €9/month for 10,000 requests, with no hidden fees or automatic upgrades. Real human support responds within 24 hours, and migration from existing CAPTCHA providers takes just minutes with reCAPTCHA-compatible APIs.
