Why merchants choose Checkout Extensions

Fraction of the cost

Rebuy starts at $99/month and scales steeply with revenue. Checkout Extensions is $49.99/mo flat, regardless of order volume.

Live in minutes, not weeks

No developer setup, no widget configuration, no AI training period. Add a block from the Shopify Checkout Editor and it's live.

Checkout-native architecture

Built specifically for Shopify's checkout extensibility API — not a widget injected into themes. Faster, more reliable, and Shopify Plus compliant.

All blocks in one app

Trust badges, branding, countdown timers, gift messages, custom fields — all the checkout blocks Rebuy doesn't cover.

Choose Rebuy if…

If you have a large catalogue, need AI-powered recommendation algorithms, and want a smart cart experience across your entire store — not just checkout.

Choose Checkout Extensions if…

If you want to quickly add high-converting checkout blocks without a large investment in setup, configuration, or monthly cost.

Common questions

Is Checkout Extensions much cheaper than Rebuy?

Yes. Rebuy's pricing scales with GMV and can reach several hundred dollars per month for larger stores. Checkout Extensions is flat $49.99/mo (Starter) or $99.99/mo (Pro).

Does Checkout Extensions have AI recommendations like Rebuy?

Checkout Extensions uses manual product selection for upsells, not AI. This means you control exactly which products appear at checkout — often the better choice for stores with a clear bestseller lineup.

Can I use Checkout Extensions alongside Rebuy?

Yes. If you use Rebuy for smart cart and homepage recommendations, Checkout Extensions can handle your checkout-specific blocks (trust badges, branding, countdown timer, custom fields) where Rebuy has limited coverage.

How long does it take to set up Checkout Extensions?

Most merchants are live within 30 minutes. Install the app, choose your blocks in the Checkout Customizer, configure settings, and click Save.
