About

Duckity protects application APIs from automated abuse without showing users captchas. It combines rate limiting, network signals and verifiable computational challenges based on a VDF, with policies that define expected behavior. SDKs cover JavaScript, TypeScript, Python, Rust and React, and data is processed in Frankfurt, Germany.

Why it made the leaderboard

Offers a captcha-free abuse defense that works cross-platform, including native and terminal sign-up flows, and does not block legitimate agents.
