    About Caddy Web Server

    Caddy is a powerful, enterprise-ready, open-source web server with automatic HTTPS written in Go. It is designed to be simple, efficient, and secure by default, distinguishing itself as the first web server to use HTTPS automatically. Caddy handles TLS certificate renewal, OCSP stapling, and HTTP-to-HTTPS redirects out of the box without manual intervention. The server is highly extensible through a modular architecture, allowing users to add functionality such as DNS providers for ACME challenges, specialized logging, or integration with external databases. Configuration can be managed through the human-friendly 'Caddyfile' or a native JSON API, enabling dynamic infrastructure changes without downtime. While primarily a community-driven project, it offers a commercial store for plugins and support.
