Rules and logic
Show, hide, force or reprice options based on what the buyer already picked. The same rules run in the browser and on our server, with identical results.
Visual builder and preview
A step-by-step builder with a layered preview
Each answer brings its own transparent layer for every view of the product. The builder stacks them in order, so the preview always shows exactly what the buyer picked. You set it up in a full-screen editor inside Shopify Admin.
Layers, views and steps
A customizer has steps, each step has questions, each question has answers. An answer can carry one image per view: front, back, side, detail. Layers stack by question order, with a per-answer override when a part has to sit above something else. Buyers switch views with buttons or a swipe.
No flicker when a part changes
The builder keeps the current picture on screen until every new layer has loaded, then swaps them in one go. Layers for the other views load in the background once the page is idle, so flipping to the back of the product is instant.
An editor made for big option trees
The admin editor has three panes: a tree of steps, questions and answers on the left, the real storefront builder in the middle, and properties on the right. Drag to reorder. Pick an answer in the preview and the editor selects it in the tree.
Names and pictures from buyers
Text and image upload questions draw straight into a print area you place on each view: position, size and rotation. A typed name or an uploaded photo shows on the product as the buyer adds it, and lands on the design images your team gets with the order.
Bulk upload that finds the right answer
Name your exported layers like front__body__red.png and drop a whole folder in. The editor matches each file to its view, question and answer, converts it to WebP and lists anything it could not place. The asset library tracks where each image is used and will not let you delete one that is still live.
