Score: 6.0/10 (Innovation: 6, Technical: 6, Documentation: 4, Utility: 6)

Duckity is a bot protection service using VDF-based proof-of-work challenges to make abusive behavior increasingly costly, without relying on CAPTCHAs or AI detection. It offers platform-agnostic SDKs and customizable policies, positioning itself as a privacy-friendly, UX-preserving alternative. The approach is interesting for its focus on computational cost rather than identification.

Target audience: backend developers, devops, security engineers
