Privacy-first CAPTCHA solution that blocks bots invisibly while keeping forms accessible. EU-based, no cookies, no tracking, easy integration.
European security & identity alternative based in Estonia.
Private Captcha is an Estonian, EU-only bot protection service built on invisible cryptographic proof-of-work challenges. There are no puzzles for users to solve, no PII collected, and every byte of infrastructure — servers, storage, and CDN — stays inside the European Union.
Operated by Intmaker OÜ, Private Captcha is open source on GitHub and offers a self-hosted option for teams that need full control. Backward-compatible APIs make switching from reCAPTCHA or hCaptcha straightforward.
Key features:
- Invisible cryptographic challenges — proof-of-work with automatic difficulty scaling
- No PII from end users — no cookies, no tracking, DPA provided on all plans
- EU-only infrastructure — exclusive EU servers, storage, and CDN
- Self-hosting option — run it on your own servers for full sovereignty
- Open source — code available on GitHub, fully auditable
- Audit logs — compliance-ready logging across all events
- Real human support — 24-hour business-hour response target
- 10+ languages with multiple display modes and widget customisation
Pricing starts at €9/month for the Basic tier (10,000 requests/month) with all features included across tiers. 14-day free trial with no credit card required, and pro-rata refunds plus auto-upgrade protection on usage spikes.
