Zepto Product Personalizer is built to personalize a product. The customer types a name, picks a font, drops in a photo, and sees the result before they pay.
Pricing is a different job. If your price comes from a size, a material and a quantity, you need a pricing engine, and that's what Appify Custom Product Options is built on. It shows a live preview too, so you keep the personalizing and gain the pricing, on every plan.
Here is where Zepto fits, where it stops, and the alternatives worth installing.
What Zepto does well
Zepto puts personalization on the product page. It offers text and monogram fields, fonts, colors, swatches and file uploads, all with a live preview. It can also build one product from several components.
Options show and hide with conditional logic, and any choice can carry a price. That charge can be a flat amount, a percentage of the Shopify product price, a percentage of the charges before it, or a price per letter of text. It also connects to print-on-demand partners such as Gelato and ShineOn.
Where it fits: products where the personalization is the point and each choice adds a set price.
Where it stops: the moment the customer types a size. Its listing describes charges on choices and doesn't mention measurement pricing, formulas or rate tables, so a banner, a wallpaper order or a made-to-measure blind becomes a list of sizes, each with its own price. With Appify Custom Product Options the customer types the size, and the price comes from your rate sheet.
What a pricing-heavy product needs
Before you install the next app, run your hardest product through these questions.
- Can the customer type a size and get a price for exactly that size?
- Can it read your rate sheet as written, to the row or between rows?
- Do quantity breaks follow the size? A large banner and a small one rarely get the same discount.
- Can it add a setup fee and hold a minimum on the whole job?
- Can one choice price another? Premium vinyl costs more per square foot, not a flat extra.
- Can you see why a price is wrong, before a customer finds it?
1. Appify Custom Product Options
The price is made from everything the customer picks. It updates as they build the product, and the calculated total is what they pay at checkout.
Price from the size the customer types
Formulas run on any option and on the total price. You can name a step with a pricing variable, such as the area, and reuse it in the price, the discount and the shipping weight.
A formula can look up your price sheet. Put the rates in a pricing table, width by height or size by material, and the price reads the right cell. It can match exactly, take the nearest row, or blend between rows for a size you never listed.
You don't need to write the formula yourself. Type "width times height times 3.50 per square foot, never under 50" into the Describe with AI tab, and it returns MAX(50, INPUT("WIDTH") * INPUT("HEIGHT") * 3.50) with your own option names.
A customer types 4 feet by 2 feet. That is 8 square feet, so the formula gives 28.00 and the minimum lifts the price to 50.
Every rule on your rate card
- Quantity breaks that follow the size. Discounts can depend on quantity alone, or on quantity and on width or area together.
- Fees. A setup fee on every order, or a rush fee only when Rush is picked. Fixed fees are never discounted.
- Minimum and maximum price on the total, so no job goes out under your floor.
- Price adjustments. Add a percentage when the material is premium, or a flat charge when the area passes a size you set.
Personalizing, with a live preview
Personalization layers the customer's text, uploads, colors and swatches onto the product image as they choose. A proof image of the finished product is saved with the cart line and the order.
For goods where the design is the product, such as stickers, wallpaper and prints, the Product Designer is a separate feature. It gives the customer a full design canvas at real size, and you get print-ready files and cut lines with the order. Appify Custom Product Options has both.
You don't build it by hand
Describe the product to Chat with AI, or attach the price sheet you already use. It builds the options, the formulas and the rules, and you can edit anything it writes.
When a price comes out wrong, the Troubleshoot tab runs the formula with the choices you're testing, shows the value of every part, and names the fix. Explain formula turns any formula back into plain English.
The options survive the order
Customers can use Edit options to change a configured item from the cart. A reorder brings back the original choices, and Restore your cart in abandoned checkout emails brings back the whole cart with its customizations.
Who it's for: any store whose price comes from a size, a rate sheet or a rule, with or without personalizing on top. For the setup in depth, see how to set up formula-based pricing on Shopify.
2. SE: Option Price Calculator
You'll meet other names while searching, so here is how they line up. SE: Option Price Calculator is the next most capable formula engine after Appify Custom Product Options. It puts formulas on every option and on the final price, reads pricing tables and lookups, and uses product metafields in formulas.
It also calculates weight by formula, shows and hides options by rule, and offers quantity breaks. Shopify Markets currency and option translation are built in. It's a focused calculator for measurement-based products, and a strong one.
Appify Custom Product Options adds the wider engine around the formula, plus the personalizing and design side: if/then logic, fees, minimums, troubleshooting, AI setup, the live preview and the Product Designer.
3. Easify Custom Product Options
Easify is another name you'll meet. It adds choices to a product page, each with a price, and has a measurement formula on a higher plan: up to three typed numbers times your rate.
Where it fits: choice-driven products, plus one area price.
Where it stops: the order for a large size in bulk. A discount that changes with both the quantity and the size needs a two-way grid. In Appify Custom Product Options each break can depend on quantity and on width or area, and applies automatically at checkout.
Easify gets its own look in Easify alternatives for advanced pricing.
4. Globo Product Options, Variant
Globo takes a similar approach. Choices carry add-on prices, and its dimension option has a measurement formula on its top plan.
Where it fits: choice-driven products priced by add-ons.
Where it stops: the premium material. Globo's formula takes the typed numbers and your rate, and doesn't read the material or the finish. In Appify Custom Product Options one formula reads the size and the material together, so premium costs more per square foot.
Globo has its own comparison in Globo alternatives for formula pricing.

Moving from Zepto
You don't have to start from a blank page.
- Start from a screenshot. Drop a screenshot of your product page into Chat with AI and it sets up the options from the image. Here's how to turn a screenshot into a calculator.
- Add your pricing. Attach your price sheet as a CSV or Excel file, or describe how you price in plain English. See turning a pricing spreadsheet into a Shopify pricing system.
- Keep the personalizing. Text, uploads, colors and swatches can show on the product image as the customer chooses, with a live preview.
- Test before it's live. Check the preview against a few real orders. Nothing reaches the storefront until you publish.

How to decide
If your customers personalize a product and your price comes from a size, a material and a quantity, Appify Custom Product Options is the one to install. It prices the whole rate card, shows the preview, and writes the setup for you if you'd rather not.
If you're weighing the other apps, SE: Option Price Calculator is the next most capable formula engine. On pricing, choosing Zepto, Easify or Globo is choosing fewer features, not different ones.
