About
Cap is an open-source, self-hosted 
reCAPTCHA alternative that verifies visitors without visual puzzles, tracking, or third-party services.
It uses a two-layer verification model that combines proof-of-work challenges accelerated with 
WebAssembly and Web Workers, including SHA-256 hashing and optional GPU-resistant time-locks.
hCaptcha is a security service for detecting and preventing human and automated abuse on websites and applications, often used as a drop-in alternative to reCAPTCHA.
It uses machine learning-driven bot detection and risk scoring without collecting personal data for GDPR, CCPA and global privacy compliance, and offers customizable challenge types and passive modes to reduce user friction.
