Overview
A web server often used for automatic HTTPS and reverse proxying.
Definition
A web server often used for automatic HTTPS and reverse proxying.
Real-world example
After DNS for staging.example.com points to your VPS, Caddy requests a Let's Encrypt certificate and begins proxying traffic once the upstream app passes health checks.
Common mistake
Blocking ports 80/443 on the firewall while expecting automatic HTTPS - ACME HTTP-01 validation needs inbound port 80.
Better-PaaS in practice
Better-PaaS manages Caddy site blocks per app. You add domains in the UI; certificate renewal is handled by Caddy without manual certbot cron jobs.
FAQ
Is Caddy only relevant to Better-PaaS?
No. Caddy appears across Docker, cloud platforms, and self-hosted tooling. Better-PaaS exposes the concept in deploy logs, dashboard fields, or docs when it affects your app.
