Theia: Product Customizer

Theia turns any product into a personalized, print-ready product. Customers design directly on the product page — typing text, uploading images or sending print files — while you define the exact print area. Add custom options like dropdowns, swatches and date pickers, support front and back designs with color variant mockups, and download the original full-quality files from every order. No code needed: add the block from your theme editor in seconds.
