What Cartly actually does
Cartly focuses on the slide cart / drawer experience: presenting line items, incentives, and upsell surfaces without forcing a full cart page round-trip.
The upside is cognitive — fewer steps for buyers who already intend to check out.
The risk is integration: discount apps, subscription widgets, and Shopify’s own checkout evolution all sit adjacent to this surface.

Pros & cons
- Can tighten mobile flows when the default cart feels dated.
- Merchandising in-cart can be easier than reworking entire PDP templates.
- Often faster to trial than full theme rewrites.
- Another script on the critical path — measure performance honestly.
- Conflicts with aggressive theme customizations happen; budget QA time.
- May overlap native Online Store 2.0 cart app blocks — compare before paying.
App Store screenshots
Marketing screenshots from the Shopify listing — in-admin UI may look different. Always verify on a duplicate theme.
Before you spend trial time
- Duplicate theme and run Lighthouse on collection → product → add to cart.
- Test Shop Pay / wallet buttons after drawer edits.
- Verify discounts, taxes, and shipping previews match the cart page.
- Read 3-star reviews referencing specific themes.
- If you already customized cart.liquid heavily, expect surgery.

Closing take
Cartly is a UX investment — worthwhile when cart friction shows up in qualitative feedback or abandoned sessions with intent signals.
If your theme cart is already modern, you may not need another layer.
