## What it is
Numa is a portable DNS resolver in a single Rust binary that provides ad blocking, local .numa service domains, hostname overrides, and privacy-preserving ODoH encrypted queries. It runs on macOS, Linux, and Windows as a system service with a built-in web dashboard and optional public ODoH relay mode.

## Use cases
- block ads and trackers on any network via DNS
- give local dev services friendly .numa domain names with HTTPS
- override hostnames temporarily with auto-revert
- encrypt DNS queries with ODoH for privacy
- run a local DNS server with DNSSEC validation
- run a public ODoH relay endpoint
- reverse-proxy local dev servers with path-based routing

## When to choose
- you want a single-binary, cross-platform DNS resolver with ad blocking built in
- you need local HTTPS domains for development without mkcert or /etc/hosts
- you care about DNS privacy and want ODoH or DNS-over-TLS
- you want to contribute to the ODoH relay ecosystem

## When to avoid
- you need a full enterprise DNS server with zone management or DHCP
- you require BIND/Unbound feature parity like complex zone delegation
- you only need ad blocking and prefer a lighter hosts-file-based tool
