Caddy

Caddy is an enterprise-grade web server written in Go, featuring automatic TLS certificate provisioning by default, modern HTTP/3 support, and concise configuration syntax.

When to Use

• Automated TLS & Reverse Proxying: Instant HTTPS certificates issued via Let's Encrypt / ZeroSSL with zero manual setup.
• Modern Microservice Edge Proxy: HTTP/2 and HTTP/3 reverse proxying with clean, human-readable Caddyfiles.
• Local Development HTTPS: Issuing trusted local root certificates automatically for development environments.
• Zero-Downtime Hot Reloading: Updating configurations via REST API or caddy reload without dropping connections.
