# How to publish your app

> Publish your Hercules app to make it live. Click Publish, pick a subdomain, and go live in seconds. Republish to ship new versions.

Publishing makes your app live on the internet. Every app gets a free `[myapp].onhercules.app` domain, and you can add a custom domain anytime.
