Protect forms with privacy-first captcha

Founded by: Taras Kushnirin 2025

You can use Private Captcha to protect your website forms and APIs from bot traffic while staying GDPR compliant. It runs an invisible cryptographic challenge in the background instead of making users solve puzzles. The service automatically adjusts difficulty based on bot activity, requires no user interaction, and doesn't collect any personal data. All infrastructure is EU-based and the code is publicly available for auditing or self-hosting.
