# Build from source
There are 2 ways to build Caddy, as opposed to installation of pre-built executable:
- Build from Git repo
- Build using `xcaddy`
Requirements:
- [Go](https://golang.org/doc/install) 1.20 or newer
You can easily cross-compile, i.e. build Caddy on one operating system or architecture for a different, using the same tooling. You'll find details on this in the respective section.
The latest section contains instructions for users who installed Caddy using the APT command on Debian-derivative system yet need the custom build executable for their operations.
## Build from Git repo
Requirements:
- Go installed (see above)
Clone the repository:
<pre><code class="cmd bash">git clone "https://github.com/caddyserver/caddy.git"</code></pre>

Go programs are easy to compile for other platforms. Just set the `GOOS`, `GOARCH`, and/or `GOARM` environment variables that are different. ([See the go documentation for details.](https://golang.org/doc/install/source#environment))
## xcaddy
For example, to compile Caddy for Windows when you're not on Windows:
<pre><code class="cmd bash">GOOS=windows go build</code></pre>
Or similarly for Linux ARMv6 when you're not on Linux or on ARMv6:
<pre><code class="cmd bash">GOOS=linux GOARCH=arm GOARM=6 go build</code></pre>
## Build using `xcaddy`
The [`xcaddy` command](https://github.com/caddyserver/xcaddy) is the easiest way to build Caddy with version information and/or plugins.

As you can see, you can customize the versions of plugins with `@` syntax. Versions can be a tag name, commit SHA, or branch.
Cross-platform compilation with `xcaddy` works the same as with the `go` command (see below).
