InstantPWA on BigCommerce
BigCommerce ships a Script Manager in the control panel specifically so merchants can add third-party scripts without editing Stencil theme code. Add InstantPWA as a footer or head script scoped to 'All pages' and it goes live across your storefront immediately, including on Catalyst storefronts.
Script Manager is available on every BigCommerce plan, including trial stores.
How to set it up
- 1
Open Script Manager
Storefront → Script Manager → Create a Script.
- 2
Set location to Head and pages to All pages
Choose 'Script' as the type and paste the InstantPWA snippet as inline HTML.
- 3
Save
BigCommerce Script Manager scripts apply store-wide with no deploy step.
- 4
Enable cart-abandonment targeting
Scope a second trigger to /cart.php so the popup can nudge shoppers who leave items behind.

FAQ
Do I need a developer to edit Stencil templates?+
No — Script Manager avoids theme files entirely, so it survives theme updates and switches.
Does this work on Catalyst (headless) storefronts?+
Catalyst storefronts render with Next.js, so use the Next.js install guide instead — Script Manager only injects into Stencil-rendered pages.
