About Prosopo
What is Prosopo?
Prosopo is an open-source, privacy-first CAPTCHA and bot-defense company. Its flagship product, ProCaptcha™, is a frictionless, GDPR-compliant alternative to Google reCAPTCHA and hCaptcha — designed to block bots, scrapers, credential stuffing, and account takeovers without the invasive user-tracking and high price tag of incumbent solutions.
The company protects 1,000+ active websites, completes more than 1 billion secure verifications a month, and stops over 100 million bots per month. Its three pillars are explicit: Privacy-First (minimal data collection, no tracking, no data sales), Open Source (fully transparent, auditable, community-driven — codebase at github.com/prosopo/captcha), and Cost-Effective (transparent pricing with a free-forever tier). The product is WCAG 2.1 compliant and runs at >99.9% uptime.

What is the Prosopo team like?
Prosopo is a small, focused engineering team building open-source bot defense for the modern web. The company was originally kickstarted by a grant from the Web3 Foundation and was featured at Polkadot Decoded 2022 in Berlin as a W3F grant recipient.
Customer feedback consistently highlights both the product and the team's support. Theo: "I've installed Prosopo's CAPTCHA widget on my website to filter out spam from my contact form. Getting it working was a little bit tricky but the support from Chris has been first class." Nathan G praised the React NPM wrapper, inline-CSS styling, and theming support. Damjan reported switching from hCaptcha and reCaptcha and seeing greatly reduced friction and churn.
