Do I have to manage the SSL certificates?

No. Caddy automatically obtains and renews Let's Encrypt certificates, with no cron or certbot.

Does Caddy replace Nginx?

For most use cases (reverse proxy, websites, HTTPS), yes — with far simpler configuration.

About Caddy

Caddy is a web server and reverse proxy that handles HTTPS automatically: it obtains and renews your Let's Encrypt certificates without any intervention. Its configuration fits in a few lines (Caddyfile), which makes it the ideal tool for cleanly exposing your applications.

On your ServOrbit VPS, Caddy places your applications (Coolify, n8n, Netdata, API…) behind a secure reverse proxy with a valid SSL certificate from the very first startup — no certbot or cron configuration.

Guide

Deploy Caddy on your VPS

Install Caddy
Install the official package: apt install -y debian-keyring debian-archive-keyring apt-transport-https && apt install caddy. Caddy starts as a systemd service.
Configure the Caddyfile
In /etc/caddy/Caddyfile, declare your domain and the target: app.exemple.ma {\n reverse_proxy localhost:3000\n}. Caddy obtains the certificate on its own.
Reload
systemctl reload caddy — your application is served over HTTPS, certificate included.
