FB Variant Image vs Rubik Variant Images.

What each app is for

Both apps do the same basic job. They change how your theme shows the variants you already have in Shopify. Neither one adds new options or custom fields. They make the variant picker and product images easier for shoppers to follow.

If you are weighing FB Variant Image, Color Swatch vs Rubik Variant Images & Swatch, start with how much display control you need.

The FB Variant Image listing describes a free variant image gallery app with custom image swatches and single or dual-color swatches. The feature tags Shopify shows are Swatches, Conditional logic, Custom CSS, Custom HTML and Variants display. The “works with” list names combined listings and product groups. The app launched on the App Store on April 14, 2026, and on October 26, 2026 it showed 5 stars from 46 reviews. That is a small review count, so it is worth testing on your own store before relying on it.

The Rubik listing says it shows only the selected variant’s images and adds image or color swatches to the variant picker. It carries the same five tags as FB Variant Image, plus 18 more. These include Dropdowns, Hide out-of-stock, Stock availability, Carousel, Slider, Grid, Lightbox, Video, Image zoom, Hover effects, a Drag-and-drop editor and Multi-language. It launched on October 18, 2024 and showed 5 stars from 497 reviews on the same date.

Both listings carry the Built for Shopify badge.

Price and plans in practice

For FB Variant Image, the math is short. The pricing line says Free, with one Free plan and no paid tiers. A small store pays nothing. Because there is nothing to upgrade to, no trial is shown, and none is needed.

Rubik works differently. Its Free Plan covers 1 product, so it is a way to try the app on a live store, not a way to run swatches across a full catalog. To use it on more products, you would move to a paid plan:

• Starter Plan: $25 a month, or $200 a year
• Advanced Plan: $50 a month, or $400 a year
• Premium Plan: $75 a month, or $600 a year

Each paid plan shows a 7-day free trial, and the yearly price saves 33%. A small store on Starter would pay $25 a month, or $200 for the year if it pays up front. The billing note says all charges are in USD and recurring charges are billed every 30 days. The listing does not show any intro offer. Neither listing says its price depends on your Shopify plan.

Theme support, setup and help

The FB Variant Image listing states “full compatibility with all Shopify themes and page builders.” The developer’s pages do not publish a list of tested themes.

Craftshift’s FAQ says Rubik supports 350+ Shopify themes, including Dawn, Prestige, Impulse, Impact, Focal, Palo Alto, Symmetry, Stiletto and Broadcast. It also keeps a supported themes page split into Shopify free themes, Theme Store themes and other themes. Of the 61 themes Techiepugs tracks, the developer’s pages name 58, including Horizon, Dawn, Refresh, Empire, Turbo and Warehouse. If your theme is on that list, you have a written statement to point to.

Neither listing gives setup steps in the facts, such as whether you turn on a theme app embed.

For help, the FB Variant Image listing says support comes from FulbiX and links to an FAQ. It does not state which support channels are offered. The app is listed in 1 language.

The Rubik listing says support comes from Craftshift, and the Free Plan line shows live chat and email support. It links to an FAQ, a tutorial and app documentation, and the app is listed in 16 languages.
