The caddy version command prints the version of the Caddy binary.

​
Usage

caddy version

​
Description

Prints the version of this Caddy binary. Version information must be embedded into the binary at compile-time for Caddy to display anything useful with this command. If Caddy is built from within a version control repository, the Go command will embed the revision hash if available. However, if Caddy is built in the way specified by the official documentation (or by using xcaddy), more detailed version information is printed as given by Go modules.

​
Output

The output format includes:
  • Version number - The Caddy release version (e.g., v2.7.6)
  • Module path - The Go module path
  • Module sum - The Go module checksum
  • Build metadata - Compiler version, platform, etc.

​
Example Output

$ caddy version
v2.7.6 h1:w0NymbG2m9PcvKWsrXO6EEkY9Ru4FJK8uQbYcev1p3A=
For a more detailed build, the output might look like: 
v2.7.6 h1:w0NymbG2m9PcvKWsrXO6EEkY9Ru4FJK8uQbYcev1p3A=
module: github.com/caddyserver/caddy/v2
version: v2.7.6
sum: h1:w0NymbG2m9PcvKWsrXO6EEkY9Ru4FJK8uQbYcev1p3A=
go: go1.21.5
platform: linux/amd64

​
Exit Codes

  • 0 - Success

​
Version Information

The version string follows the Go module version numbering scheme. See the Go module documentation for more details.

​
Version Format

Versions follow semantic versioning:
  • v2.7.6 - Major.Minor.Patch
  • v2.7.6-beta.1 - Pre-release version
  • v0.0.0-20230101120000-abc123def456 - Pseudo-version (built from specific commit)

​
Building with Version Info

​
Using xcaddy

The recommended way to build Caddy with proper version information: 
xcaddy build v2.7.6
This embeds the version automatically.

​
Custom build with version

go build -ldflags "-X 'github.com/caddyserver/caddy/v2.CustomVersion=v2.7.6'"

​
Building from source

If you build from source without special flags: 
git clone https://github.com/caddyserver/caddy.git
cd caddy/cmd/caddy
go build
The version will be based on the git commit: 
v2.8.0-0.20240101120000-abc123def456

​
Checking Version Programmatically

In scripts, you can parse the version: 
VERSION=$(caddy version | awk '{print $1}')
echo "Caddy version: $VERSION"
Or check if a minimum version is installed: 
REQUIRED="v2.7.0"
CURRENT=$(caddy version | awk '{print $1}')

if [ "$(printf '%s\n' "$REQUIRED" "$CURRENT" | sort -V | head -n1)" = "$REQUIRED" ]; then
    echo "Version check passed"
else
    echo "Caddy $REQUIRED or higher required"
    exit 1
fi
