OptionForge
Add to your store
Shopify product options

Product options that charge correctly — every time.

Add engraving, gift wrap, size, color, file uploads and more — with price add-ons applied server-side at checkout. No phantom products. No “$0” mischarges.

Install free from the Shopify App Store.

Charged server-side

Add-ons are applied by a Shopify Cart Transform Function. The cart total always matches what the shopper saw — the charge can’t silently fail.

No phantom products

Unlike legacy apps, OptionForge never creates hidden “phantom” variants that clutter your catalog and break carts.

Every option type

Text, dropdown, radio, swatches, checkboxes, number, date and file upload — plus conditional logic to show or hide options.

How it works

  1. 1
    Build option sets

    Create reusable options with prices and assign them to products.

  2. 2
    Shoppers personalize

    A clean widget on the product page shows a live add-on total.

  3. 3
    Charged at checkout

    The exact add-on is applied server-side — and shows on the order.
