A domain name you attach to a deployed application. Learn what custom domain means in self-hosted deployment and Better-PaaS workflows.

Overview

A domain name you attach to a deployed application.

Definition

A domain name you attach to a deployed application.

Real-world example

Create an A record for app.example.com → 203.0.113.10, add the domain in Better-PaaS, wait for DNS propagation, then confirm HTTPS is active.

Common mistake

Adding the domain in the dashboard before DNS points at the server, causing repeated Let's Encrypt failures.

Better-PaaS in practice

Domains are per-app in the dashboard. Caddy obtains certificates once DNS resolves to your server and the app is healthy.

FAQ

Is custom domain only relevant to Better-PaaS?

No. custom domain 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.
