OP Color Swatch vs Variants King.

What each app is for

If you’re weighing OP Color Swatch Variant Images vs Variants King & Color Swatch, start with how your products are built. These two apps do different jobs, even though both show swatches.

OP Color Swatch Variant Images, from OPTIS, works on the variants you already have. The listing says it replaces your theme’s text variant picker with color and image swatches, variant images and stock badges. Your product setup in Shopify stays the same, and only the display changes.

Variants King & Color Swatch, from StarApps, is a combined listing app. The listing says it groups separate products into one combined listing joined by color swatches. It can also do the reverse and split variants into their own products for SEO.

Where they overlap: both listings tag swatches, dropdowns, radio buttons, variant display, low stock alerts, hiding out-of-stock items, translation, and import and export. The Variants King listing also tags custom text, file upload, dates, conditional logic, gift wrap, size charts, add-ons, variant upcharges and tiered pricing. The OP listing tags nothing the Variants King listing lacks.

Both carry the Built for Shopify badge. Both launched in 2025. As shown on October 26, 2026, OP has 5 stars from 801 reviews and Variants King has 5 stars from 457 reviews.

Price and plans in practice

Neither app has a free plan for a normal live store. The OP free tier covers trial, Partner and development, Pause and Build, and staff stores. The Variants King free tier is for Shopify Partner stores only.

On both apps, the price follows your Shopify plan. Here is what a store would pay each month, as shown on October 26, 2026:

• OP, single plan: $11.90 on Basic, $29.90 on Grow, $49.90 on Advanced, $99.90 on Plus. The card says all features are included on every plan.
• Variants King Standard: $14.90 on Basic, $29.90 on Grow, $49.90 on Advanced, $99.90 on Plus, and $5 for Pause and Build stores.
• Variants King Pro: $29.90 on Basic, $59.90 on Grow, $99.90 on Advanced, $199.90 on Plus, and $10 for Pause and Build stores.

So a small store on the Basic plan would pay $11.90 a month for OP, or $14.90 for Variants King Standard. The Variants King plan notes shown do not list what Pro adds over Standard. Check that before you choose a tier.

Each paid plan has a 30-day free trial. Neither listing states an intro offer or discount. Both bill in USD every 30 days.

Theme support, setup and help

OPTIS says the app works with all Shopify themes. It names Dawn, Sense and Refresh, and says most third-party themes work too. If you use a different theme, ask OPTIS to confirm it before your trial ends.

StarApps states nothing about theme support on the Variants King listing or the developer pages we could read. If you run a third-party theme, ask StarApps about it during the trial.

For help, the OP listing says OPTIS offers 24/7 live support and links to an FAQ and a tutorial. The app is listed in 23 languages.

The Variants King listing shows live chat support and onboarding help on the Standard plan. It does not list help resources such as an FAQ or tutorial. The app is listed in 12 languages.

Each app also lists apps it works with. OP names the developer’s own combined listings and product options apps, plus Translate & Adapt. Variants King names Swatch King and Variant Image, along with page builder and filter apps.
