Caddy is a modern, open-source web server designed to simplify the often complex and frustrating process of hosting websites. Developed by Matthew Holt in 2014 as a response to the steep learning curve and configuration nightmares associated with traditional servers like Apache and Nginx, Caddy introduced a revolutionary approach: making secure web hosting automatic and effortless. Its standout feature, automatic HTTPS via Let's Encrypt, eliminated the need for manual certificate management, which had long been a source of frustration for developers and non-technical users alike. Built in the Go programming language, Caddy offers speed, security, and simplicity through its human-readable Caddyfile configuration system, allowing even beginners to deploy secure websites with minimal effort. The project quickly gained traction among developers, small business owners, students, and hobbyists who wanted to focus on building content rather than wrestling with infrastructure. Despite early licensing drama that sparked community debate over commercialization and sustainability, Caddy evolved into a fully open-source, enterprise-ready solution backed by Apilayer, ensuring continued development and innovation. Today, Caddy powers trillions of HTTPS requests, supports modern technologies like HTTP/3 and QUIC, and serves as a reverse proxy in complex environments including Docker and Kubernetes. It plays a crucial behind-the-scenes role in ensuring fast, secure, and seamless online experiences for millions of users worldwide. With an active global community contributing code, documentation, and support, Caddy continues to push the boundaries of what a web server can be—simple, powerful, secure, and adaptable to future needs.
