+title: Building Anubis without Docker
+---
+
+:::note
+
+These instructions may work, but for right now they are informative for downstream packagers more than they are ready-made instructions for administrators wanting to run Anubis on their servers.
+
+:::end
+
+## Tools needed
+
+In order to build a production-ready binary of Anubis, you need the following packages in your environment:
+
+- [Go](https://go.dev) - the programming language that Anubis is written in
+- [esbuild](https://esbuild.github.io/) - the JavaScript bundler Anubis uses for its production JS assets
+- [Node.JS & NPM](https://nodejs.org/en) - manages some build dependencies
+- `gzip` - compresses production JS (part of coreutils)
+- `zstd` - compresses production JS
+- `brotli` - compresses production JS
+
+## Install dependencies
+
+```text
+go mod download
+npm ci
+```
+
+## Building static assets
+
+```text
+npm run assets
+```
+
+## Building Anubis to the `./var` folder
+
+```text
+go build -o ./var/anubis ./cmd/anubis
+```
+
+From this point it is up to you to make sure that `./var/anubis` ends up in the right place. You may want to consult the `./run` folder for useful files such as a systemd unit and `anubis.env.default` file.
