Kustomly: Product Personalizer

Let shoppers personalize products with text, dropdowns, file uploads, and paid add-ons.

Kustomly turns any product into a personalized one. Add custom fields — text, paragraphs, dropdowns, numbers, dates, checkboxes, and file uploads — to the products you choose. Allow paid add-ons and option upsells, show a live preview as shoppers type, and reveal fields only when relevant with conditional logic. Every answer is saved to the order as line-item properties, so you always know what to make. Add it to your product page from the theme editor — no code required.
