Visual builder
Buyers pick parts, colors and add-ons step by step and watch a layered preview update with every choice, on any phone.
Multi-currency and languages
Sell the same customizer in every market
Moddify Studio is built in the EU for stores that sell across borders. One customizer serves every language and currency your Shopify store is set up for.
Labels in every store language
Step, question and answer labels hold one text per locale. A translation view in the editor puts every buyer-facing string side by side with a missing count, and exports and imports CSV for your translator. The builder's own buttons and messages come in English, Spanish, German and French, and you can override any of them per store.
Prices in the buyer's currency
Prices live in your shop currency. The builder converts them with the same rate and the same integer math the checkout function uses, so a buyer paying in euros sees the exact amount they will be charged.
Rounding per market
Round totals up to an ending such as .95, and set a different ending per currency, for example x9.99 in euros. Rounding applies to the total only, the same way at checkout.
Hosted in the EU
The app and its data are hosted in the European Union and operated by a Polish company. Shopify's GDPR webhooks are handled.
More features
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.
Pricing and checkout
Live prices in the builder and native checkout pricing through a Shopify Cart Transform function. No hidden price variants cluttering your catalogue.
Production and orders
Every answer carries a production code. Orders arrive with design images, a clean list of parts, the buyer's uploads and tags set by your own rules.
API and integrations
A read API for orders, designs and published customizers, and signed webhooks the moment a design is ordered.
Analytics
A funnel from builder opened to ordered, how far buyers get through the steps, and which answers bring in orders and revenue.
Theming
A small, fast builder designed at 360 px first. Styled with CSS tokens and theme editor settings, with stable class names for anything else.
