Publishing and sharing
Going live, custom domains, and inviting your users.
Preview vs live: how publishing works
Your changes are visible to you instantly. They're visible to your users when you publish. Here's the difference.
Connecting your own domain
Use your own web address — like myapp.com — instead of the default one.
Run the Security Review before you publish
Before you go live, run the built-in Security Review from the publish flow to catch common vulnerabilities — exposed secrets, unsafe HTML, and weak input handling — in your app.
