Sometimes it’s a little confusing to see exactly what changed behind the scenes or which adjustment caused the biggest impact, especially when multiple things are optimized at once. but overall we clearly saw site load times drop after installing it. I also like that it works automatically in the background and doesn’t need constant attention or manual tweaking to keep things running well.

Page load times dropped pretty fast after setup, especially on mobile which was our main issue before. the dashboard could be clearer and a bit more beginner-friendly, but once you understand it, the performance gains are definitely worth it and noticeable across the store.

Love that i didnt need any tech skills to use this. Crazyload did most of the optimization for me and now pages load much faster even during high traffic times.

Nice tool for optimizing performance. sometimes I’m not totally sure what changed, but the speed gains speak for themselves and bounce rate dropped a bit.

its been good so far but some of the features took me a bit to understand. overall tho it helped reduce load times especially on mobile which was a big win for us.

Honestly I forgot I even installed it until I checked my analytics later. Pages were loading faster and bounce rate was slightly better.

My shop has a ton of photos and it used to feel heavy. Crazyload made it significantly faster, at least that’s what my analytics are showing.

I dont know much about optimization stuff but my site definitely feels snappier. Customers even commented that it loads quick now.

I work on Shopify stores constantly, and I’m pretty picky about performance tools. A lot of “speed apps” promise improvements but end up injecting heavy scripts, messing with lazy loading, or creating layout shifts that cause more problems than they solve. CrazyLoad is one of the rare apps that actually improves performance without breaking anything.

I’ve been using CrazyLoad for months now, and the difference it makes is so noticeable that I forget what my store used to feel like before. I only really remembered when I temporarily disabled it during a theme update and everything suddenly felt… slower, heavier, almost sticky. That’s when it hit me just how much this app had been doing in the background.
