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.

Key features

Automatic HTTPS (Let's Encrypt / ZeroSSL) with zero configuration
Simple reverse proxy and load balancing
Readable configuration in just a few lines (Caddyfile)
HTTP/2 and HTTP/3 (QUIC) by default
Automatic certificate renewal
Compression, security headers and static file serving built in

When to use this solution?

1

SSL for your apps

Expose Coolify, n8n or your API over HTTPS with a valid certificate, automatically.

2

Reverse proxy

Route several applications on a single VPS via subdomains, each over HTTPS.

3

Static sites

Serve a website or a SPA with compression and HTTPS without any additional web server.

Deploy Caddy on your VPS

Guide optimized for ServOrbit Cloud VPS.

01

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.

02

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.

03

Reload

systemctl reload caddy — your application is served over HTTPS, certificate included.
