Switching from SA Variant Image Automator to Rubik Variant Images: a migration guide
SA Variant Image Automator has been around since 2017 and does the basics well. But if you are hitting limitations with its image order-based approach, its Shopify plan-based pricing, or you want features like AI image assignment, there are reasons to look at alternatives.
Rubik Variant Images takes a different approach: metafield-based image storage, AI auto-assign, Shadow DOM swatch rendering, and flat pricing. This guide covers what changes when you switch, what you need to redo, and what you can skip.

Why merchants switch
Based on what we hear from merchants who have made the switch:
- Image order-based assignment is fragile. SA uses the position of images in your Shopify gallery to determine which images belong to which variant. If you reorder images, add new ones, or delete one from the middle, assignments can shift. Rubik uses explicit metafield-based assignments that do not change when you rearrange your gallery.
- No AI assistance. SA does not mention AI features on their listing. Rubik’s AI auto-assign analyzes each image visually and assigns it to the correct variant. For stores with hundreds of products, this saves days of manual work.
- Shopify plan-based pricing adds up. SA charges $14.90/month on Basic, $29.90 on Shopify, $49.90 on Advanced, and $99.90 on Plus. Rubik charges $25/month for 100 products regardless of your Shopify plan. On Advanced and Plus, Rubik is significantly cheaper.
- Theme compatibility issues. Some SA reviews report problems with custom themes. Rubik explicitly supports 350+ themes with 8 detection methods and 7 page builders.
- Swatch customization. Rubik has 100+ CSS variables for swatch styling, an AI visual settings assistant, and Shadow DOM isolation. SA’s swatch customization options are not detailed on their listing.
What changes between the two apps

| AI auto-assign | Not mentioned | Yes (Claude AI) |
| Bulk assign | Not mentioned | Yes (image-order based grouping) |
| Swatch rendering | Standard injection | Shadow DOM isolation |
| Data storage | Not specified | Shopify metafields |
| Theme support | “All themes” | 350+ themes, 7 page builders |
| Pricing | Shopify plan-based ($14.90-$99.90) | Flat ($25-$75) |
| Video/3D support | Yes | Yes |

Step-by-step migration
- Install Rubik Variant Images while SA is still active. You can have both installed simultaneously during migration. Do not uninstall SA yet.
- Enable the Rubik app embed in your theme editor (Customize > App embeds). Keep SA’s embed off for now.
- Start with one product. Open it in Rubik, assign images to variants (manually or with AI auto-assign), save, and preview on the storefront. Confirm the gallery filtering works.
- Use bulk assign for the rest. If your image filenames contain color names, bulk assign can handle hundreds of products at once. For generic filenames, use AI auto-assign product by product.
- Disable SA’s app embed in the theme editor once Rubik is working on your products.
- Test 5-10 products across different colors and devices. Check mobile and desktop.
- Uninstall SA when you are confident Rubik is working correctly across your catalog.
The entire process takes a few hours for a store with 100 products. Most of that time is spent on bulk assign or AI auto-assign, which runs in the background.
What happens to your existing image assignments
SA’s image assignments do not transfer to Rubik. The two apps use completely different systems: SA reads image positions in the gallery, Rubik stores explicit assignments in metafields.
You need to reassign images in Rubik. This sounds like a lot of work, but AI auto-assign and bulk assign make it fast:
- AI auto-assign: Open a product, click the AI button, review the results. Under a minute per product.
- Bulk assign: If filenames contain color names, hundreds of products are processed in the background. Minutes, not hours.
Your images themselves are not affected. They stay in Shopify’s media library. Only the assignment data is different between the two apps.
Pricing comparison
| Your Shopify plan | SA cost | Rubik cost (100 products) | You save |
|---|---|---|---|
| Basic ($39/mo) | $14.90/mo | $25/mo | SA is $10 cheaper |
| Shopify ($105/mo) | $29.90/mo | $25/mo | $4.90/mo with Rubik |
| Advanced ($399/mo) | $49.90/mo | $25/mo | $24.90/mo with Rubik |
| Plus ($2,300/mo) | $99.90/mo | $25/mo | $74.90/mo with Rubik |
On Basic, SA is cheaper. Starting from Shopify plan, Rubik saves money. On Plus, the difference is $74.90/month ($899/year). And Rubik includes AI auto-assign, which SA does not offer.

Frequently asked questions
Can I run both apps at the same time during migration?
Yes. Install Rubik and set up your products while SA is still active. Keep only one app embed enabled at a time to avoid conflicts on the storefront. Disable SA’s embed before enabling Rubik’s.
Will my images be deleted if I uninstall SA?
No. Your images are in Shopify’s media library. Neither app deletes your images when uninstalled. Only the assignment data (which images belong to which variant) is app-specific.
How long does migration take?
For a store with 100 products using bulk assign or AI auto-assign, a few hours. For stores with 500+ products, bulk assign runs in the background and handles it overnight. The actual storefront switchover (toggling app embeds) takes seconds.
