Scope verdict

Ownership reviewed, controller unresolved

This service remains visible for context, but it is not counted or recommended as a European-controlled option.

How we classify services

Private Captcha is a captcha service that protects forms and APIs without asking visitors to solve puzzles or watching how they behave. The browser completes an invisible cryptographic task in the background, and the difficulty adjusts automatically so real users pass quickly while bots face a cost that grows with volume. Because the check is cryptographic, it holds up as AI tools improve.

The source code is public, no cookies are set and visitors are not tracked, which keeps GDPR compliance simple. All infrastructure and suppliers sit in the EU, among them Bunny CDN, Hetzner and Scaleway, so it is a European alternative to American captcha services.

Pricing

Pricing depends on the number of monthly captcha requests and starts at 9 euro per month for 10,000 requests, billed monthly or yearly at a discount.
