Caddy is an **open source Go community project**. The official site provides **Download**, **Documentation**, **Forum**, **GitHub**, **Account**, **Support**, and **Sponsor** links.

For self-hosted use, Caddy offers downloads for platforms including **Linux**, **macOS**, **Windows**, **FreeBSD**, **OpenBSD**, and **Dragonfly**, across architectures such as amd64, arm, arm64, mips, ppc64, s390x, and loong64. The download page lists **Standard features** and **Extra features**, and supports custom builds with **xcaddy**.

Notes from the official download page: “Only choose plugins you need and trust.” Due to “multiple outstanding bugs in the go command,” some downloads may hang or fail; “you can download Caddy from the latest release on GitHub, or use xcaddy for custom builds.”
