I've been using this app for a few months and I've been super happy with my store speed! The dashboard is the first thing I check after making changes to my theme. The support team is great and super responsive as well. Highly recommend! ^^

I recently started using the Thunder app, and the results have been phenomenal! My Shopify store's loading time has significantly improved, and my customers have noticed the difference. The interface is user-friendly, making it easy for someone without a technical background to navigate and implement optimizations. The support team is outstanding—they responded to my queries promptly and even provided personalized suggestions to further enhance my store's performance.

I'm really impressed with this app. It's not just about speed improvements - it helped me identify other issues I didn't even know I had. My First Contentful Paint dropped from 7s to 1.6s, which is huge! Big shoutout to Georgi - I was shocked when he replied to my support request within a minute. That kind of responsiveness is rare these days. The interface is straightforward, so you don't need to be a tech wizard to use it. If you're looking to seriously boost your site's performance, give this a shot. It's been a lifesaver for me

Before installing Thunder Page Speed Optimization, my site was experiencing slow load times, which affected the customer experience and, ultimately, conversions. But with Thunder, everything changed. Now, it’s hands down the best solution to speed up my Shopify store!

Great app that was easy to set up and improved my site speed significantly without much trouble. But what sets them apart is their support: I was able to speak directly with the owner right off the bat, who was very responsive, and he even ended up helping me solve a problem that wasn't even related to his app! Having a real person to help me with my unique problem is important to me as a sole business operator who doesn't have a tech background, and it's definitely kept me from looking at other page speed apps!

I highly recommend using the app and working with George. He helped me with optimizing my store and resolved critical issue with CLS (visual stability problems). I think an app like that is the future of online store optimizations. I must also add that I am a newbie to subject like this, I always feel dizzy while talking with developers - but not with George. He has high communication skills and I understood everything he said and every process he showed and explained. I appreciate the experience and results.

Most apps do not improve Google page speed! This is the best app I have ever tried to speed up the site, showing noticeable improvements even on the page speed! It's very simple: After installing it, just go to "Optimize," leave the level on "Standard," and click on "Generate optimized preview." That's it :) The plus of this app is competent and always available support that will help you with any doubts or problems! Thank you, Georgi, for the help!
