Yes, the JSON Schema App works with BigCommerce Stencil themes.

Stencil is the modern BigCommerce storefront framework, and apps can integrate with it to add features such as JSON-LD structured data to store pages.

The app retrieves store data through the BigCommerce API and injects the required schema markup into pages such as:

• Product pages
• Category pages
• Homepage and general pages

This allows structured data to work correctly across Stencil-based BigCommerce storefronts without requiring manual theme modifications.
