Caddy has established itself as a modern web server that prioritizes developer experience and security by default. Its automatic HTTPS with Let's Encrypt or ZeroSSL integration, HTTP/3 support, and simple configuration language make it an increasingly popular choice for web hosting environments where ease of operation matters.
Why Caddy for Modern Hosting
Caddy's defining feature is automatic TLS certificate management. Simply specifying a domain name in the Caddyfile triggers automatic certificate provisioning, renewal, and OCSP stapling without any manual configuration. For hosting providers managing thousands of domains, Caddy's on-demand TLS feature issues certificates dynamically as requests arrive for configured domains.
The Caddyfile configuration format dramatically reduces configuration complexity compared to NGINX or Apache. A reverse proxy with automatic HTTPS, HTTP/3, compression, and security headers can be configured in five lines, reducing misconfiguration risk and enabling faster provisioning of new hosted sites.
Caddy's extensibility through plugins provides capabilities like automatic image optimization, Cloudflare DNS challenge support for wildcard certificates, and rate limiting. Its API-driven configuration allows hosting platforms to manage Caddy configurations programmatically, integrating seamlessly with automated provisioning systems and control panels.
