Every extra page load between “add to cart” and “checkout” loses conversions — and the cart page is the biggest one. XootiX Woocommerce Side Cart Premium keeps the cart one click away: an AJAX sliding cart that opens from any page, lets customers manage items, apply coupons, calculate shipping, and complete one-click express checkout — all without ever leaving the page they’re on.
It’s the highest-rated plugin in its category — 4.9 stars across 450+ reviews on wp.org, 80,000+ installs, nearly 1.9 million downloads since 2017 — and the Premium layer is where the conversion mechanics live: rewards progress bars, save-for-later, coupons, and cross-sells inside the cart. Here’s the working review at 4.8.8.
Competitive Features
- Rewards and checkpoints system. Multiple progress bars showing real-time progress toward free shipping, free gifts, and discounts — based on cart total or quantity, with checkpoints accepting decimal values, fixed discounts added alongside percentage-based ones, gift product filtering, and a “limit to highest gift” option. The gamification layer most cart plugins bolt on externally is native here.
- One-click express checkout. PayPal, Google Pay, Apple Pay, and Amazon Pay directly from the side cart — the express-payment buttons exactly where cart abandonment gets decided.
- Save for Later. Customers move items out of the cart into a personal save list without losing track — the hesitation-handling feature that keeps “still deciding” shoppers in the flow instead of bouncing.
- Coupons in the cart. Apply coupons directly from the cart, view available codes, and browse upcoming coupons — the “add more to save more” mechanic, monetized.
- In-cart upsells and cross-sells. Upsells, cross-sells, related, or custom products render in three styles (drawer, slider, column) — customers add products without leaving the cart.
- Shipping calculator in-cart. Customers update their shipping location and see exact fees — the cart page’s last remaining job, eliminated.
- Variable product quick view. Customers change their selected variation options directly in the side cart — the edge case most side carts crash on.
- Full totals transparency. Quantity controls plus itemized taxes, fees, and discount breakdowns — the checkout-quality math in the cart.
Key Features
- AJAX cart with real-time updates. Add, remove, and update quantities without page reloads; subtotal updates live; quantity update moved into the free version in 2.8.0 — the core mechanic done well enough to earn the category’s best rating.
- Floating basket with menu integration. A cart menu item showing item counts, addable to multiple menus (4.8.1), hideable when empty, with custom basket images and multiple icon choices.
- Deep customization. Cart width, height, colors, layout, header layout, card/row layouts, button themes — the appearance layer covers nearly everything, with sale-vs-regular price display options.
- Notifications on cart updates. Real-time notifications on every add/update/delete — feedback that keeps users engaged.
- Fly-to-cart animation. The visual feedback on add-to-cart — small UX detail, measurable conversion effect.
- Zero-configuration setup. Activate and it works — the free tier’s own positioning, and the reviews confirm it.
- Broad plugin compatibility. WPC Composite and WPC Bundle savings compatibility added in 4.8.x — the cart interacts correctly with composite-product plugins, the common conflict source.
- 22 locale translations. Full translation coverage across major languages.
Comparison with Competitors
XootiX Side Cart vs Flycart Discount Rules (conversion stack comparison)
Adjacent conversion layers that pair rather than compete: the side cart manages the flow, the pricing engine manages the price.
| Aspect | XootiX Side Cart | Flycart Discount Rules |
|---|---|---|
| Layer | Cart UX and retention | Pricing campaigns |
| Coupon handling | In-cart application and display | Rule-based auto-apply |
| Rewards | Progress bars native | Bulk/BOGO mechanics |
| Together | Cart keeps customers engaged | Engine prices what they add |
The discount rules engine prices the cart; the side cart keeps customers inside it — and the in-cart coupon display works with either rule layer.
XootiX Side Cart vs CartFlows Pro (checkout architecture)
The comparison that decides cart architecture for a store: persistent cart versus funnel checkout.
| Aspect | XootiX Side Cart | CartFlows Pro |
|---|---|---|
| Model | Sliding cart on every page | Replaced checkout pages |
| Customer flow | Browse with cart always present | Guided funnel steps |
| Setup | Zero config | Funnel design |
| Best for | Catalog browsing stores | Offer-driven funnels |
The funnel builder restructures checkout entirely; the side cart improves the standard WooCommerce flow. Stores with wide catalogs benefit from the persistent cart; offer-driven stores benefit from funnels — some run both on different product lines.
Recommended Stack: The sliding cart pairs with the discovery layer that feeds it — the FiboSearch instant search gets customers to products fast, and the side cart keeps the purchase path open once they add — together they compress the browse-to-checkout journey to near zero page loads.

Frequently Asked Questions
Does the sliding cart replace the cart page?
Effectively, yes — customers manage quantities, apply coupons, calculate shipping, and check out without ever visiting a cart page. The cart page still exists for anyone who navigates there, but the side cart handles the whole flow in place.
Is the GPL version the full Premium plugin?
Yes. The GPL build is the complete Premium source under its original license — rewards, save-for-later, coupons, one-click checkout, and cross-sells all enabled. The vendor license key for auto-updates is the only absence.
Can I use it on multiple sites?
The GPL license permits unlimited installations across personal and client sites without per-domain activation.
What are the rewards and checkpoints?
Progress bars track cart total or quantity toward rewards — free shipping, free gifts, or discounts. Multiple bars run simultaneously, checkpoints accept decimal values, gifts can be filtered and limited to the highest tier, and 4.8.8 specifically fixed the tax calculation inside reward thresholds.
How does Save for Later work?
Customers move items out of the cart into a personal save list without losing track of them — the “still deciding” pattern captured instead of lost. The 4.8.5 release specifically fixed the crash that occurred when a saved product no longer existed.
Does it work with variable products?
Yes — Premium adds a quick view for variable products and lets customers change their selected variation options directly in the side cart, plus the 4.9.x line added quick view for variable products. Compatibility with WPC Composite and Bundle plugins is built in.
