Full disclosure before anything else: Keystone is our product. This comparison is written by the team behind Keystone Product Options, so read it knowing where we stand. We have kept every number verifiable - pricing and ratings come from the Shopify App Store listings of both apps, as of August 2026 - and we say plainly where Easify is the better pick.
Easify Custom Product Options and Keystone Product Options solve the same core problem: Shopify's native variant system runs out of room fast, and stores that sell customizable products need option sets that go beyond it. Both apps carry the Built for Shopify badge. The differences show up in who each app is built for.
TL;DR verdict
- Easify (4.9 rating, 2,922 reviews, launched 2023) is the stronger pick for personalization-heavy B2C stores: its $19.99 Premium plan adds a live preview personalizer, text effects, and background removal that Keystone does not offer.
- Keystone (4.5 rating, 21 reviews, launched 2025) is the stronger pick for B2B and wholesale stores: B2B catalog pricing at $29.90, shared option sets across products, and phone support from $9.99 - none of which appear on Easify's plans.
- Easify's free plan is more generous than ours. If you only ever want a free plan, Easify is the honest recommendation.
- Both apps replace variant workarounds with proper option sets; neither requires theme code.
Pricing side by side (as of August 2026)
| Plan | Easify | Keystone |
|---|---|---|
| Free | Free Forever: 15 option types, 100+ templates, unlimited option sets, products and orders, conditional logic for Easify options, option performance tracking | Free: 10 option sets, 12 option types, unlimited products, analytics dashboard |
| First paid tier | $9.99 Pro: 28 option types, price formulas (per character, one-time), multi-file upload (10 files, 10MB each), conditional logic with Shopify variants, date picker | $9.99 Essentials: unlimited option sets and types, price add-ons, priority live chat and call support |
| Second paid tier | $19.99 Premium: live preview personalizer, text effects, background removal, image and color swatch sliders | $29.90 Premium: conditional logic, shared options, B2B catalog pricing, top-priority chat and call support |
| Top tier | $99.99 Enterprise: done-with-you onboarding, custom tweaks on request, custom integrations | None - $29.90 is the ceiling |
Two things stand out. First, Easify gives away more at $0 - unlimited option sets and its own conditional logic sit on the free plan, where Keystone caps free at 10 sets and holds conditional logic for Premium. Second, the ceilings are very different: Easify's full feature set tops out at $99.99 with Enterprise, while Keystone's entire feature set costs $29.90, and onboarding help is not a paid tier.
Feature by feature
Option types and templates
Easify counts 15 option types free and 28 on Pro, plus more than 100 prebuilt templates to start from. Keystone ships 12 option types on Free and removes the type limit on Essentials. If you want to drop in a ready-made engraving form or gift-message block without building it, Easify's template library is a genuine head start.
Conditional logic
Both apps support conditional logic - showing and hiding options based on earlier choices. Easify includes logic between its own options on the free plan and logic tied to Shopify variants from $9.99. Keystone's conditional logic arrives at $29.90 Premium, where it works across option sets. If conditional logic is the only feature you need and budget is zero, Easify wins this row outright.
Price add-ons and formulas
Keystone includes price add-ons at $9.99. Easify goes further on formula pricing at the same price point - per-character charges and one-time fees are listed on its Pro plan. For made-to-order products priced by dimensions or characters, test Easify's formula builder against your price list before deciding.
File uploads and personalization
This is Easify's lane. Pro takes 10 files at 10MB each; Premium adds a live preview personalizer, text effects, and background removal. Keystone supports file uploads for custom orders, but we do not offer a live preview canvas or image editing. A print-on-demand store whose buyers want to see their design on the product before checkout should shortlist Easify first.
B2B and wholesale
This is Keystone's lane. B2B catalog pricing - different option pricing for wholesale buyers - is built into our $29.90 Premium plan, and shared options let you maintain one option set across an entire catalog instead of duplicating it per product. Easify's listed plans include neither. If retail and wholesale buyers hit the same product pages, this single row can decide the comparison.
Support
Easify staffs 24/7 human live chat on every plan, including free, and its reviews reflect it. Keystone offers live chat on Free and adds call support from $9.99 - being able to get a human on the phone while configuring option sets is rarer than it should be in this category. Easify's equivalent of hands-on onboarding lives in the $99.99 Enterprise plan.
Where Easify genuinely wins
- The free plan. Unlimited option sets, conditional logic, and 100+ templates at $0 is more than Keystone gives away.
- Personalization depth. Live preview, text effects, and background removal at $19.99 have no Keystone equivalent.
- Review base. 2,922 reviews at 4.9 versus our 21 at 4.5 - Easify has far more public track record, and that is worth weight in any honest comparison.
Where Keystone wins
- B2B catalog pricing at $29.90 - wholesale-specific option pricing that Easify's plans do not list.
- Shared options - one option set maintained across many products, instead of per-product duplication.
- Call support from $9.99 - phone plus chat, where Easify is chat-only until Enterprise onboarding at $99.99.
- A $29.90 ceiling. Every Keystone feature costs less than a third of Easify's Enterprise tier.
Switching between the two
Neither app writes option data into your theme, so switching is lower-risk than it looks: install the new app, rebuild option sets (Keystone's Essentials plan has no set limit, so staging everything before going live costs nothing extra), test a handful of products in an unpublished theme copy, then disable the old app's storefront embed and enable the new one. Run both installed - but only one embedded - for a day or two so you can revert instantly. Existing orders keep their option data either way, since options are stored as line item properties on the order.
Bottom line
If your store sells personalized B2C products and your buyers expect to preview their customization live, Easify is the better tool and we would rather tell you that than have you churn. If your store serves wholesale buyers, needs different option pricing for B2B, maintains one option catalog across many products, or simply wants a human on the phone without a $99.99 plan - Keystone does those specific things at $29.90 or less, and Easify's listed plans do not do them at any price.
