What the preview is
The preview is a private, running copy of your app, for you, while you work. It is not the address you share.
To get a shareable link, see Publish your site.
What each message means
The preview is honest about its state instead of showing a blank frame. The small status pill above the pane and the message inside it tell you where things stand.Sleeping and waking

- Just send your next message — sending wakes it automatically.
Sleeping never loses work. Your files are restored into the new machine when it wakes.
Controls

- The preview shows your app, not a status message.
- Changes you asked for appear within a few seconds of the Builder reporting them.
- The layout holds up when you narrow the window.
