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.

The siteverify endpoint validates a Friendly Captcha solution token. The server POSTs the token and API key (with optional sitekey) and receives a JSON response indicating success, risk score, IP intelligence, bot detection signals, and any error codes. This is the canonical server-side check for protected form submissions and API calls.

The Friendly Captcha widget is the JavaScript component that runs the proof-of-work puzzle in the browser and produces a solution token. It is configured via a script tag and a div with the sitekey and API endpoint, and can run automatically or on demand.
