Every package PrivateCaptcha depends on, ranked by repo health score.
PrivateCaptcha is an independent, EU-built CAPTCHA service that replaces traditional image puzzles with background Proof-of-Work challenges. Instead of asking users to identify fire hydrants or traffic lights, it silently runs cryptographic hash computations in the browser — blocking bots and AI scrapers without collecting any Personally Identifiable Information or disrupting the user experience.
The system is designed from the ground up for privacy compliance. No behavior tracking, no third-party cookies, no PII processing. All infrastructure — servers, CDN, email — runs exclusively on EU-based providers, making it a natural fit for organizations that need to satisfy GDPR, data sovereignty, or security audit requirements that forbid third-party data processing.
Self-hosting is a first-class use case. The source code is publicly available, Docker-based deployment is documented, and an OpenAPI specification covers the full public API. Difficulty adapts automatically based on traffic patterns, scaling the computational burden on clients as bot activity increases while keeping the experience smooth for legitimate users.
PrivateCaptcha is built for sustainability: a managed SaaS offering funds continued development, while the community edition lets organizations run everything on their own infrastructure under a noncommercial license.
