Build from source


  • Go 1.14 or newer

Clone the repository:

git clone ""

If you don't have git, you can download the source code as a file archive from GitHub. Each release also has source snapshots.


cd caddy/cmd/caddy/
go build


The xcaddy command is the easiest way to build Caddy with version information and/or plugins.


  • Go installed (see above)
  • Make sure xcaddy is in your PATH

You do not need to download the Caddy source code (it will do that for you).

Then building Caddy (with version information) is as easy as:

xcaddy build

To build with plugins, use --with:

xcaddy build \

As you can see, you can customize the versions of plugins with @ syntax. Versions can be a tag name or commit SHA.

Cross-platform compilation with xcaddy works the same as with the go command (see below).


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.)

For example, to compile Caddy for Windows when you're not on Windows:

GOOS=windows go build

Or similarly for Linux ARMv6 when you're not on Linux or on ARMv6:

GOOS=linux GOARCH=arm GOARM=6 go build

The same works for xcaddy. To cross-compile for macOS:

GOOS=darwin xcaddy build
