Helping Shopify Merchants Create, Customize, and Sell Without Limits
Custy exists to make one thing effortless for Shopify merchants: letting customers design the product they are about to buy, right on the product page, without slowing the store down or creating work for the people who have to print it.
Whether it's a t-shirt, hoodie, cap, mug or any print-on-demand product, shoppers get real creative freedom and you get artwork your production team can actually use.
What defines Custy
- Built specifically for Shopify merchants and POD workflows
- Embedded in Shopify admin and built on Shopify Polaris
- A real design studio, backed by a pricing engine built for printing
- Print-ready artwork on every order, at up to 300 DPI
- English and French out of the box, with GDPR webhooks in place
Our Vision
We believe the future of eCommerce is personalization. Customers no longer want generic products. They want something unique, something personal.
Personalization Is the Future
Modern shoppers expect more than a standard product page. They want products that feel personal, expressive, and meaningful. Custy helps merchants meet that demand with a customization experience that stays simple for the customer and practical for the business.
Turning Products into Experiences
A product a customer helped design is a product they are more invested in. Instead of offering just another item on a shelf, stores can offer creativity, ownership, and a stronger connection between the customer and what they buy.
What We Do
Custy is a Shopify app for print-on-demand businesses, print shops, and any merchant who wants customers to personalize what they buy.
Built for POD
A full design studio on the product page and print-ready artwork on the order: the two ends of a print-on-demand workflow, connected.
Made for Custom Stores
From apparel to personalized gifts, reusable color sets, size sets and printing types mean you configure the rules once and apply them everywhere.
Focused on Growth
Shoppers who design their own product buy with more confidence, and pricing that reflects real production cost protects the margin on every order.
What customers can do
- Customize products in real time
- Design across multiple print areas like front, back, and sleeves
- Choose sizes, colors and styles, with live stock status
- Preview every side, then save the design and share a link
What merchants get behind the scenes
- Print-ready artwork as SVG, PDF, PNG or JPG at up to 300 DPI
- Order detail showing every side, color, size and price
- Bulk status updates and downloads for high-volume days
- Reusable color sets, size sets, printing types and discount sets
Who Custy Serves
Custy is built for Shopify merchants who sell products their customers help design, and who need what comes out the other end to be production-ready.
POD Businesses
Apparel and merch brands selling t-shirts, hoodies, hats and bags, with live customization and a clean handoff to production.
Print Shops
Screen print, DTG, embroidery, vinyl and sublimation, each with its own pricing rules, color limits and quantity minimums.
Promotional & Corporate Merch
Mugs, totes and giveaways carrying a client's logo, with quantity discounts and an approval step before anything reaches the press.
Growth-Focused Merchants
Any Shopify store adding personalization to an existing catalog, without creating a new SKU for every variation.
Why Custy
We didn't just build another product customizer. We built one that understands how printing is quoted, produced, and shipped.
Dynamic Pricing
Setup fees, per color, per side, per character, per square inch, size-range grids and quantity discounts, priced the way a print shop actually quotes.
Modern Print Support
Screen print, DTG, DTF, embroidery, vinyl and sublimation, each with its own color limits, minimums and pricing rules.
Seamless Shopify Integration
Embedded in Shopify admin, built on Polaris, billed through Shopify, and working on both vintage and Online Store 2.0 themes.
Fast User Experience
A canvas editor with 50 steps of undo, zoom to 3x, and a dedicated mobile layout with full touch support below 750px.
Guardrails That Protect Production
DPI warnings, print-area warnings, max-colors-per-location limits and an optional approval step keep unprintable artwork off the press.
Growth-Oriented Design
Saved designs with shareable links, re-editing from the cart, and quantity discount ladders that encourage bigger orders.
