Numa
DNS you own. Portable DNS resolver with caching, ad blocking, local domains.

Numa is a portable, single-binary DNS resolver built from scratch in Rust that runs locally on your machine. It combines ad blocking, caching, DNSSEC validation, local .numa domains for development services, and a REST API for scripting and automation. It requires no cloud account, no Raspberry Pi, and no complex setup.
A single portable Rust binary acts as a local DNS resolver that processes queries through a deterministic pipeline covering overrides, blocklists, caching, recursive resolution, and DNSSEC validation.
