Live preview, desktop and mobile
Live preview for every change you make
The preview is the real application running on real infrastructure — not a picture of it. Forms submit, data saves, navigation works.
Private by default
Previews live on a separate domain from published apps and from the platform itself, and only you and the people you allow can open them.
Desktop and phone, side by side
Switch the preview between a desktop viewport and a phone frame while you iterate, so a layout that breaks on mobile never reaches your visitors.
Your first app is a sentence away.
