Key takeaways
  • 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-site and converts the indecisive into confident buyers.

Things to watch out for

  • Spec consistency — Fudge audits product metafields and flags missing specs.
  • Mobile compare — Fudge handles this: table converts to a vertical scrollable comparison.
  • Max selection — Fudge handles this: defaults to 4; configurable.
  • Empty state — Fudge handles this: compare button hidden until at least 2 products 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.

What makes one great

  • Compare checkbox on each product card — easy selection.
  • 2-4 products supported — sweet spot.
  • Modal table — price, key specs, average rating.
  • Mobile-friendly — comparison without scroll fatigue.
