A flat price, never a share of your sales
Configured products are often your most expensive ones. Every plan is a fixed monthly fee, so a bigger order never means a bigger bill from us.
Product customizer for Shopify
Made-to-order products, designed by buyers, ready for your workshop
Moddify Studio puts a step-by-step builder on your product page: a layered preview, a live price, and rules that keep every design buildable. Shopify checkout charges the exact price, and every order arrives with the production codes your team needs.
- Flat plans, no share of sales
- Priced natively at checkout
- Free plan available
Why Moddify Studio
Built for products that are made after they are ordered
Shopify's variants stop at three options. A configured product can have thousands of valid combinations, a price for each, and a list of parts behind every order. Moddify Studio handles all of that without bending your catalogue out of shape.
Priced inside Shopify checkout
A Cart Transform function sets the price from your published customizer. No hidden price variants, no price taken from the browser.
Fast on a phone
Designed at 360 px first. About 25 KB of gzipped JavaScript, layers that swap without flicker, a sticky price bar with Add to cart.
Production-ready orders
Production codes per answer, design images per view, the buyer's uploads and a printable production sheet for every order.
Rules that keep designs buildable
Hide, force or reprice options based on earlier choices. One engine runs in the browser, at checkout and on our server, with identical results.
Open to your own systems
A REST API for orders, designs and customizer definitions, signed webhooks when a design is ordered, and design images rendered on our server for every view.
How it works
From layer files to a packed order
- 01
Build it in the editor
Steps, questions and answers in a full-screen editor inside Shopify Admin. Drop in your layer files and they match themselves to answers by file name.
- 02
Add the block to the product
Pick the Moddify Studio block in the theme editor, set colors and layout, publish. Your store's theme stays in charge of the look.
- 03
Buyers design and buy
The preview and price update with each choice. Add to cart sends one line with the design attached, and checkout charges the computed price.
- 04
The order lands ready to build
The design is frozen with the order, price re-checked, tags applied and production codes written to the order for your team.
Try it live
This is the real builder
The same script your buyers would load, running a demo sneaker with four steps, a rule or two and live pricing. Pick a black sole and the coral collar lining disappears from the extras. Turn on the monogram patch and an initials field appears. Nothing here talks to a store.
What your store would receive
Press Add to cart in the demo. In a real store, the cart line carries a readable summary for the buyer, and hidden properties that the checkout function and our backend use to price and rebuild the design.

Visual builder
Buyers pick parts, colors and add-ons step by step and watch a layered preview update with every choice, on any phone.

FAQ
Questions merchants ask first
Do you take a percentage of my sales?
No. Every plan is a flat monthly price billed through Shopify. A configured product that sells for $1,500 costs you the same as one that sells for $15.
Does it create hidden variants on my products?
No. The configured price is set at checkout by a Shopify Cart Transform function that reads your published customizer. Your products keep only the variants you created.
Does it work on my theme?
The builder is a theme app block for Online Store 2.0 themes, so you add it in the theme editor like any other block. An app embed can also place it on customizable products without editing templates.
What does the order look like on Shopify Plus and on other plans?
On Shopify Plus the configured product is one cart line at the exact price. On other plans it becomes a bundle: the base product plus a component for each priced part linked to a variant. In both cases the order carries the design summary and production codes.
Can I show different options depending on earlier answers?
Yes. Rules can hide questions or answers, force an answer, or change an answer's price when a condition matches. The same rules run in the browser, at checkout and on our server.
Can buyers upload their own pictures or add a name?
Yes, on Growth and up. Text and image upload questions draw into print areas you place on each view, so the buyer sees the result in the preview, and the order gets the original files and rendered design images.
Is there a free plan?
Yes: one customizer with up to 10 questions and 50 customized orders a month, with a small "Powered by Moddify Studio" link. Paid plans start at $79 a month, or $790 a year with 2 months free, after a 14-day free trial.
