Blockasaurus: Pi-Hole-like DNS server with DoH, DoTLS upstream, and more
[Mods: this is my open source DNS server project. If you won't allow it here, just delete]
Blockasaurus is an open-source blocking DNS server clone/alternative to Pi-Hole.
I built this out of frustration with Pi-Hole. I wanted DoH/DoTLS upstream support and first-class support for running in Kubernetes home labs. I wanted every configuation change to live-reload without as restart. I wanted Prometheus metrics and a UI that didn't depend on PHP and an external web server.
Most of the UI will be very familiar to you, but there are a few key differences:
- Blockasaurus is built on top of the core of Blocky, a tried-and-true nameserver written in Go. Blocky is built into Blockasaurus and handles the DNS; Blockasaurus provides the UI and the REST API to Blocky configuration, which was moved to a SQLite DB.
- Blocky supports DoH and DoTLS natively. This includes upstreams, and also includes listeners: you can set your own DoH endpoint up w/ a Lets Encrypt wildcard TLS cert
- Like Blocky, Blockasaurus is written in Go and ships as a single, do-it-all executable. One binary provides the nameserver, serves the web UI, and handles the REST API.
- It's great for home labs. It comes with a Helm chart!
- Blockasaurus does not currently have a DHCP server
- Blockasaurus is designed to be the DNS server supporting evan-proxy, a blocking proxy servers for teenagers' phones.
I consider this a beta product, but I've been running it at my busy home for quite a while now and it's doing great.
