Add a 'Compare' checkbox to each product card on the collection page. When 2–4 products are selected, show a 'Compare' button that opens a modal table comparing the products by price, key specs, and average rating.
- Up to 4 products compared side-by-side.
- Specs pulled from product metafields.
- Price, rating, and Add to cart per column.
- Compare state persists across collection pages.
What you're trying to do
For considered purchases (supplements, skincare with active ingredients, electronics, fitness gear), shoppers naturally compare. Without a built-in compare tool, they open 4 tabs and copy-paste specs to a notes app. A real compare table keeps them on your site and helps undecided shoppers choose.
Things to watch out for
- Spec consistency: Fudge audits product metafields and flags missing specs.
- Mobile compare: the table turns into a vertical, scrollable comparison.
- Max selection: 4 by default, and you can change it.
- Empty state: the compare button stays hidden until at least 2 products are selected.
How Fudge does it
Fudge duplicates your live theme into a draft, builds the section as an editable Shopify section with the placement and behavior your prompt requires, and wires it to your real product data and brand styling. Everything starts in draft — preview on your store, tweak via the Theme Editor, and publish only when you're ready. Your live store stays untouched.
When product comparison helps shoppers commit
For considered purchases with multiple similar products, a comparison feature helps shoppers commit. Click compare on 2-4 products, modal shows side-by-side specs and pricing, shopper makes the decision without bouncing to a competitor’s comparison.
When this is worth building
Build comparison for categories where shoppers compare specifications — electronics, supplements with different ingredient profiles, technical apparel. Skip for fashion or single-spec categories where comparison adds noise.

- Compare checkbox on each product card — easy selection.
