Disclosure up front: Keystone Product Options is our product. This comparison uses public Shopify App Store data, current as of August 2026, and we call out plainly where OPTIS is the better pick. Both apps carry the Built for Shopify badge, both start free, and both charge $9.99 for their first paid tier — so the real differences live in what each tier unlocks.
TL;DR verdict
- Pick OPTIS by BSS if conditional logic on a $9.99 budget is your deciding feature — Keystone doesn't unlock it until $29.90.
- Pick Keystone if you sell B2B or wholesale: B2B catalog pricing at $29.90 has no equivalent anywhere in OPTIS's lineup.
- At $9.99, Keystone gives you unlimited option types; OPTIS caps you at 15+ types until the $19.99 Platinum plan.
- The free plans are nearly identical — 10 option sets each — so trial both and judge the editor, not the price.
- OPTIS has the track record: 4.9 stars across 2,266 reviews since 2021, versus Keystone's 4.5 across 21 reviews since 2025.

The free plans: honestly, a tie
Both free plans give you 10 option sets, which is enough to run real options on a focused catalog. Keystone lists 12 option types to OPTIS's "10+", and includes unlimited products, but neither difference will decide anything for most stores. If you never plan to pay, choose whichever editor you find faster to work in — that's the honest answer.
Feature by feature
Conditional logic
This is OPTIS's strongest card. Conditional logic — showing or hiding options based on earlier choices — sits in OPTIS's $9.99 Advanced plan. Keystone gates it behind the $29.90 Premium plan. If your product pages need "choose engraving → show the text field" and your budget stops at ten dollars, OPTIS wins this one outright.
Option types and sets
The picture flips on option types. Keystone's $9.99 Essentials removes every cap: unlimited option sets and unlimited option types. OPTIS at $9.99 gives you unlimited sets but 15+ types, and you pay $19.99 for Platinum before the type list opens fully. Stores that lean on many different input kinds — swatches, dropdowns, text, quantity boxes — reach the ceiling on OPTIS's middle tier sooner.
Price add-ons
Both apps include price add-ons (charging extra for an option) at $9.99. Tie.
File uploads
OPTIS quantifies its upload story clearly: 5 file uploads at $9.99, 20 at $19.99. If customers send artwork or documents with orders and volume matters, OPTIS's published limits make planning easier.
B2B and wholesale pricing
Keystone's $29.90 Premium includes B2B catalog pricing — different option pricing for wholesale buyers on the same product pages. OPTIS lists nothing comparable at any tier; its $49.99 Unlimited plan is a Shopify Plus customization service, not a B2B feature set. If you sell to both retail and wholesale customers, this single feature usually settles the comparison.
Support
Keystone includes live chat and call support from the $9.99 plan. OPTIS offers email and live support on free, with prioritized support arriving at $19.99. Phone access at ten dollars is unusual in this category and worth weighing if you're non-technical.
Where OPTIS genuinely wins
- Conditional logic at $9.99 — a third of what Keystone charges for the same capability.
- Review base — 2,266 reviews at 4.9 stars since 2021 is a long, consistent record; Keystone's 21 reviews since 2025 simply can't match that sample size yet.
- Cart-page option editing and published file-upload limits at $19.99, useful for customization-heavy catalogs.
Where Keystone wins
- Unlimited option types at $9.99 — OPTIS asks $19.99 for that.
- B2B catalog pricing at $29.90 — absent from OPTIS's lineup entirely.
- Call support from the first paid tier, plus 12 option types and unlimited products on free.
- Shared options at $29.90 — reuse one option set across products and edit it in one place.
Switching between them
Migrating product options is far less painful than migrating loyalty points: options live in app configuration, not customer data. Rebuild your option sets in the new app while the old one keeps serving, preview on a duplicate product, then swap the theme embed. OPTIS's import/export at $9.99 helps you extract your current setup; Keystone's team walks migrations over chat or a call on any paid plan. Budget an afternoon for a typical catalog, not a weekend.
Bottom line
OPTIS by BSS is the right call when conditional logic must cost no more than $9.99, and its four-year review record earns real trust. Keystone Product Options is the better fit when you want every option type unlocked at $9.99, phone support from day one, and — decisively — B2B catalog pricing at $29.90 that OPTIS doesn't offer at any price. Both are Built for Shopify, both start free with 10 option sets: install both trials on a development store and let your own product pages break the tie.
