Kustomly: Product Personalizer

Kustomly turns any product into a personalized one with custom fields for text, paragraphs, dropdowns, numbers, dates, checkboxes, and file uploads. Shoppers can personalize products exactly how they want, while you collect every detail needed to fulfill their orders. Add paid add-ons and option upsells that apply at checkout. Show a live preview that updates as customers type. Use conditional logic to reveal fields only when relevant, keeping the experience clean and simple. Every answer saves automatically 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, works with any theme.
