Will Bundlex slow down my store?

Bundlex loads its widget asynchronously and uses your theme's existing cart flow. Like any storefront app, it adds code and network work. The effect on speed depends on the theme, enabled features, and other apps, so compare your own pages rather than expecting an unchanged speed score.

Where the code loads

• Product pages: the app embed loads the widget and renders matching published offers.
• Cart pages: the embed loads JavaScript for gift cleanup without loading the widget's stylesheet there.
• Featured-product placements: an optional featured block can load the widget where you place it, such as the home page or a landing page.

The standard embed is scoped to product and cart templates. It does not load on every collection or blog page simply because the app is installed.

How it works with your theme

The widget loads asynchronously. Bundlex uses the existing add-to-cart flow to send the selected products together, rather than installing a replacement cart drawer. Background impression and add-to-cart reporting supports analytics.

Asynchronous loading avoids blocking the initial HTML parsing, but the widget still takes time to load and render. Product data, images, and other storefront scripts can affect the result.

Check performance on your store

Compare the same product page under similar conditions, including a mobile viewport. Use a theme preview to compare the widget enabled and disabled, and repeat measurements to account for normal variation.

If you see a consistent slowdown, contact support with the product URL and the measurements. Bundlex installs through app embeds and blocks, so activation does not require editing your theme files.
