Composer
Build pages, preview them, save drafts, and deploy to visitors.
Composer is the visual editor for pages on your site. You place components, connect content, and publish when the page is ready.
Open a page
- Pick the site in the header.
- Open Composer (or a route from Sites).
- Choose the page you want to edit.
The preview loads your site. You can select components, edit fields, and rearrange layout without changing your site’s code.
Preview vs live
| In Composer | What visitors see |
|---|---|
| Save | Draft only. Visitors still see the last deployed page (or your site’s fallback). |
| Deploy | The published page on the live site. |
Preview inside Composer shows drafts immediately (?preview=true). Live visitors only change after Deploy.
Content
Connect a content source (for example your CMS) on the site, then bind documents to components under Content. See Content for variants and reusable blocks. Developers read each field from fields (for example fields.heading) using the names they registered. If a heading is empty, that name probably does not match. See Components.
Zones
Zones are regions that can show different content for different audiences. You still deploy the whole page; Amplify Up chooses the variation for returning visitors.
Checklist
- Layout looks right in preview.
- Content is connected.
- Save, then Deploy.
- Confirm the live URL (not Composer) shows the update.
