Add an install prompt to Ghost
To add an install prompt on Ghost, paste the InstantPWA snippet into Code Injection → Site Header via Ghost Admin → Settings → Code Injection → Site Header. The popup captures the browser's native install signal where supported and falls back to a guided walkthrough on iOS Safari, so every visitor sees a clear path to installing your Ghost site as an app.
Steps
- 1
Open Code Injection → Site Header
Go to Ghost Admin → Settings → Code Injection → Site Header.
- 2
Paste the InstantPWA snippet
Drop the one-line async script tag in the Ghost head section — no build step or dependency install.
- 3
Configure the trigger
In your InstantPWA dashboard, set when the popup appears — on page load, after N seconds, or after a scroll/engagement threshold.
- 4
Publish
Save/publish in Ghost so the change goes live — most builders require an explicit publish step before custom code runs.
- 5
Verify on a phone
Open your live Ghost URL on a mobile device (not the editor preview) to confirm the popup renders.
Constraints to know
- Works identically on Ghost(Pro) hosted and self-hosted Ghost 4+; no theme edit required since Code Injection is theme-independent.
- AMP versions of posts (if enabled) strip third-party scripts by spec, so the popup only appears on the canonical (non-AMP) page.
FAQ
Does the install prompt work on iOS Ghost visitors?+
iOS Safari never fires the native beforeinstallprompt event, so InstantPWA shows a share-sheet walkthrough instead — visitors still get a clear add-to-home-screen path.
Will this conflict with other scripts on my site?+
No — InstantPWA is a single first-party async script with no third-party dependencies, so it doesn't block or compete with analytics or chat widgets.
Do I need to touch anything else in Ghost besides Ghost Admin?+
No — the head snippet is the only integration point; InstantPWA hosts the manifest and service worker for you.
