Score: 6.3/10 (Innovation: 6, Technical: 7, Documentation: 6, Utility: 6)

Numa is a Rust-based DNS tool that implements ODoH (Oblivious DNS over HTTPS), providing anonymous DNS resolution by splitting the query path between a relay and a target server, so neither sees both the user's IP and the question. It includes a client, relay, and public deployment in one binary, using audited crypto libraries like odoh-rs and rustls, and aims to give self-hosted users a privacy-focused DNS option without accounts or platform lock-in.

Target audience: backend devs, devops, security engineers
