Hello, dear hunters! 🦌

Tired of slow, privacy-invasive CAPTCHAs that frustrate your users and hell to maintain?


Behold P-Captcha — a self-hosted, open-source CAPTCHA SDK for bot protection with a focus on developer experience, simplicity and performance. Developers deserve better captchas, so I built one that’s easy to integrate and customize.

Why P-Captcha?

🚀 Zero dependencies. Seriously. 2Kb Gzipped.
⚡ Low performance footprint: Runs in background using web-workers.
🔒 Full user privacy: Absolutely no data collection.
🎨 Fully customizable: Simple and practical interface .
🔧 Easy integration: Comes with a React widget out of the box.
