How it works

This package is built with maturin and distributed as platform-specific wheel files. Each wheel bundles a pre-compiled Caddy binary with the caddy-snake plugin (caddysnake-cli). The Python CLI wrapper (caddysnake_cli.py) uses click to parse arguments and then executes the bundled Caddy binary with os.execv.

The package is built and published automatically on tagged releases by the python-build.yml GitHub Actions workflow.
