Caddy is a modern web server with automatic HTTPS. Nginx is more performant and flexible.

• Simple Caddyfile
• HTTP/3 out of the box
• Go extensible

Caddyfile — that’s all you need for HTTPS reverse proxy¶

example.com { reverse_proxy localhost:3000 }

Nginx¶

• Most flexible configuration
• Huge ecosystem and community
