Add product options and paid add-ons, charged accurately at checkout—no phantom products.
OptionForge adds product options and personalization to any product—then charges the add-ons correctly. Prices are applied server-side by Shopify's Cart Transform, so cart and checkout totals always match what the shopper selected, with no phantom products. Options include text, dropdowns, swatches, checkboxes, number, date and file upload, plus conditional logic. Create reusable option sets, add them with a theme app block—no code—and import your sets from other apps.
