I Replaced Nginx With Caddy… And I’m Never Going Back

Are you still manually configuring your Nginx reverse proxy and fighting with Certbot for SSL/HTTPS certificates? Discover why Caddy, the modern web server written in Go (Golang), is quietly replacing Nginx for modern software engineering and self-hosting architectures.

In this video, Cloud Codes breaks down the system design of the Caddy web server vs Nginx. We explore the painful 28-line Nginx config versus the 7-line Caddyfile, and how Caddy's automatic HTTPS (Let's Encrypt / ZeroSSL) is saving developers thousands of hours of downtime.

We also dive deep into the 2026 benchmark results: why Caddy is 22% faster at serving small files over HTTP/2 and HTTP/3 (QUIC), but why Nginx still crushes Caddy when it comes to memory usage, large media streaming, and raw cold starts. Finally, we look at why tech giants like Stripe, Cloudflare, and Wikipedia choose the servers they do, and give you an honest verdict on which one you should use for your next project.
