WhatA managed, open-source proof-of-work CAPTCHA service that websites can deploy as a privacy-respecting alternative to Turnstile, with configurable difficulty and graceful fallbacks.
SignalMultiple developers expressed that proof-of-work is the obvious privacy-respecting solution but nobody has built a polished, easy-to-integrate managed service around it — existing options like mCaptcha are too rough for production use.
Why NowThe backlash against fingerprinting-based CAPTCHAs has reached a tipping point, privacy browsers are growing in share, and EU regulation is tightening, creating a window for a PoW-based alternative that didn't have market pull two years ago.
MarketSMB and mid-market websites needing bot protection (~5M+ sites using Turnstile/reCAPTCHA); freemium SaaS model. Competitors: Friendly Captcha (small), hCaptcha (still fingerprints). Clear gap in fully open-source managed offering.
MoatOpen-source community adoption creates distribution moat and trust advantage that proprietary competitors can't replicate; switching costs increase as customers integrate the SDK deeply.
