Friendly Captcha

Friendly Captcha is a privacy-first, GDPR-compliant bot protection service from Germany that uses proof-of-work cryptographic puzzles instead of image-labeling challenges. The widget solves a puzzle in the background while a user fills out a form, then submits a token the server validates against the Friendly Captcha siteverify endpoint. The result includes a risk verdict and additional signal intelligence (IP, bot detection, browser identification, anonymization detection). Friendly Captcha publishes open-source widgets and framework integrations for React, Vue, and Angular, plus pre-built plugins for WordPress, Magento, and other CMS platforms.
