Overview
Choosing the right side cart plugin can significantly impact your WooCommerce store’s performance. While many plugins focus on making carts look better, the real question is which one actually helps you sell more.
Caddy, built by Tribe Interactive, is a smart side cart plugin with 4,000+ active installs on WordPress.org. Version 3.0 is built on the WordPress Interactivity API and WooCommerce Store API. It was designed around revenue optimization features like comprehensive analytics, smart upsells, and multi-tier rewards that actively work to increase average order value and reduce cart abandonment.
CartPops takes a different approach, emphasizing customization and developer flexibility. With 7,000+ active installs and a 4.7-star rating, their AJAX fly-out cart offers extensive design control and developer tools, making it a strong option for stores with specific technical requirements or unique design needs.

Caddy’s strength lies in revenue-focused features that work automatically to increase sales. The analytics dashboard shows exactly which features are driving results, while the multi-tier rewards system encourages higher spending without requiring manual setup.
CartPops excels in customization flexibility. If you need specific animations, complex triggers, or deep integration with custom code, their developer tools provide the control you need.
UX and Design
Both plugins aim to create seamless shopping experiences, but they approach user experience differently.
Caddy:
Caddy is designed for store owners who want professional results without technical complexity. The visual customizer allows you to adjust colors, positioning, and styling without coding. Everything is mobile-responsive by default and designed to integrate naturally with your existing store design. The interface is clean and functional, with features like the multi-tier rewards meter that actively encourage customers to spend more.
CartPops:
CartPops provides extensive customization options for stores with specific design requirements. Their fly-out cart system supports multiple triggers and animations, giving you complete control over the customer experience. This flexibility comes with complexity. You will likely need development resources to fully utilize their customization capabilities. However, for stores with unique requirements, this level of control can be valuable.
Bottom Line: Caddy prioritizes ease of use and proven conversion patterns. CartPops offers more customization at the cost of complexity.
Performance and Architecture
Caddy:
Caddy 3.0 is built on the WordPress Interactivity API and WooCommerce Store API. These are the modern, officially supported frameworks for building interactive WooCommerce experiences. The Interactivity API handles reactive UI updates without shipping a heavy JavaScript framework, and the Store API provides a standardized, performant way to read and write cart data. The analytics tracking is designed to collect data without impacting front-end performance.
CartPops:
CartPops also uses AJAX for efficient cart updates. However, extensive use of animations and complex triggers can potentially impact performance depending on implementation. Their developer tools allow for optimization, but this requires technical expertise.
Bottom Line: Both plugins perform well. Caddy’s performance optimization is built in and aligned with where WordPress is heading. CartPops may require technical tuning for optimal speed, particularly with complex animation setups.
Pricing Comparison

- Starter: $99/year (1 site): All Pro features

CartPops Pricing:

- Pro: $89/year (1 site)
| What You Need | Caddy Cost | CartPops Cost |
|---|---|---|
| Feature-rich free cart (recommendations, save for later, rewards, coupons) | Free | $89/year (Pro for coupons, CSS) |
| Analytics, automation, abandoned cart tracking | $99/year | Not available |
| Express checkout in cart | Not available | $89/year |
| Extensive animations and developer API | Basic | $89/year |
CartPops costs $10 less for a single site. But the comparison is less about price and more about what each dollar buys. Caddy’s free version includes features that CartPops reserves for Pro (coupons, custom CSS). And Caddy Pro delivers analytics, automation, and cart recovery that CartPops does not offer at any price.
Integrations and Compatibility
Caddy
Caddy has been tested with and supports:
- WooCommerce extensions: WooCommerce Subscriptions, WooCommerce Product Bundles
- Page builders: Elementor, Divi
- Themes: GeneratePress, Flatsome, Astra, Kadence, OceanWP, Storefront
- WooCommerce standards: HPOS (High-Performance Order Storage), block theme compatible
Because Caddy is built on the WooCommerce Store API, it inherits compatibility with any plugin or theme that follows WooCommerce’s modern development standards.
CartPops
CartPops is designed for WooCommerce and should work with most standard setups. Their developer tools (PHP hooks, JS API) provide flexibility for resolving compatibility issues, but this requires technical knowledge. Fly-out cart designs generally have fewer theme conflicts since they overlay existing content rather than integrating deeply with theme styles.
Bottom Line: Caddy provides tested compatibility out of the box. CartPops offers tools to solve compatibility issues yourself.
Use Case Fit
Choose Caddy if:
- You want to increase average order value through proven optimization features
- You want detailed insights into cart performance and customer behavior
- You want to reduce cart abandonment without manual intervention
- You want everything to work out of the box with minimal setup
- You are building on modern WordPress (block themes, HPOS) and want a plugin architected for that stack
- You care about results rather than extensive customization
Choose CartPops if:
- You need highly customized cart experiences with specific animations and triggers
- You have development resources for technical implementation
- You need deep integration with custom code using extensive developer hooks
- You want express checkout directly in the side cart
- Design control is a higher priority than built-in optimization features
- You are working within a tighter budget for a single-site implementation
Final Verdict
Both plugins solve the side cart challenge effectively, but they are designed for different priorities.
Caddy is the better choice if your primary goal is increasing revenue. The focus on analytics, automation, and proven optimization features typically delivers measurable results quickly. Caddy is designed for store owners who want to improve performance without technical complexity. The free version alone includes features that CartPops reserves for its Pro tier.
CartPops works well if customization and design control are your top priorities. The extensive developer tools and animation options provide the flexibility needed for unique implementations, though this comes with increased complexity. CartPops also offers express checkout in the cart, which Caddy does not currently provide.
Most store owners care more about results than customization options. For those stores, Caddy’s revenue optimization features, modern architecture, and comprehensive free tier make it the stronger choice.
