At Kickflip, we aim to be the best product customizer on the market, and that means delivering not only advanced features but also blazing-fast loading times. Whether you’re offering custom shoes, apparel, or electronics, your customers deserve a premium experience—and speed is a big part of that.
Faster loading times for a seamless customization experience
With this latest update, Kickflip’s loading time has improved by up to 47% worldwide, ensuring a frictionless experience for your customers.
A faster product customizer translates to better engagement and higher conversion rates for your business.
Customers in certain parts of the world, such as Asia, Africa, and Oceania, will experience a more noticeable improvement in loading times due to the way internet infrastructure and content delivery networks (CDNs) operate globally. These regions often face challenges like slower internet speeds, higher latency, and fewer local server nodes compared to North America and Europe.
This improvement will also be especially noticeable for customizers with lots of images and options, as we’ve made sure to load only what’s needed first, speeding up the experience for your customers.
How did we achieve this?
Our engineering team leveraged cutting-edge technology and efficient coding practices to improve performance. Here’s a peek into the enhancements:
1. Reducing the JavaScript bundle size
By slimming down the JavaScript bundle, we reduced unnecessary overhead, allowing the customizer to load significantly faster across all devices and networks.
2. Optimizing image loading with the fetch priority browser API
Images are a crucial part of the customization experience. We leveraged the browser's Fetch Priority API to load critical images first, ensuring the visualizer is instantly ready when your customers engage.
3. Lazy loading images in the question panel
Only the images visible on the initial load are now fetched upfront. This optimization minimizes the amount of data transferred, reducing load times without compromising the user experience.
Why do faster loading times matter?
Research shows that even a one-second delay in page load time can decrease conversions by 7%. That’s why being the best product customizer isn’t just about advanced features — it’s about ensuring your customers can design their personalized products without unnecessary delays.
What’s next?
Our commitment to performance optimization doesn’t stop here. Kickflip will continue to innovate and improve, ensuring your customizers are always equipped to handle increased demand while delivering a premium customer experience.
