Numa is a DNS resolver you run yourself that gives every service on your network a real name, blocks ads and trackers before they load, and keeps your queries private with encrypted DNS. Register a frontend on port 5173 once, and https://frontend.numa opens in your browser with a valid certificate and WebSocket passthrough, no mkcert, no nginx, no editing hosts files. Path-based rules send app.numa/api to a backend on another port, so multi-service projects get one clean address instead of a spreadsheet of port numbers. Tracker and ad domains die at resolution time through the Hagezi Pro blocklist, refreshed daily, and every device that points its DNS at your instance inherits the filtering. Temporary overrides redirect any hostname for testing or debugging and revert on their own, and scripts can create them through the REST API. You choose how answers are found: forward to your existing DNS, resolve recursively from the root servers, or seal queries with Oblivious DNS over HTTPS so no single party sees both your address and your question. Phones and laptops connect over DNS-over-TLS on port 853, a QR-code flow points an iPhone at your resolver in minutes, and mDNS discovery lets one machine reach services registered on another. The dashboard on port 5380 manages services, overrides, and diagnostics, with token sign-in away from loopback. Running on a dedicated VPS on RepoCloud with guaranteed CPU, RAM, and SSD, full root SSH access, and a browser serial console. MIT licensed.
