Thunder Page Speed Optimizer

Must-have app if you care about speed and conversions. Our site performance improved almost immediately, and the team helped us optimize things we didn’t even know were slowing us down. Easy to use and great support.

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.

This app is fantastic! My website’s loading speed improved instantly, boosting user engagement and SEO. The interface is user-friendly, and it provides clear insights and actionable fixes, plus the support team is excellent. A must-have for anyone looking to optimize their site!

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.

The best app for page speed optimizer он тхе маркет. I tried all the apps on the market and things always got worse. Here, with just a click of a button, I raised my site speed twice. It was down to under 40, now it's up to 79!
Congratulations to the team and admiration for the amazing support.

I recently started using this app for my store, and I've been absolutely blown away by the results! Within 15 minutes, my pagespeed score DOUBLED (40 to 80!!!) and my speed score in Shopify has been increasing every day. Special shoutout to George. His expertise, quick responses, and willingness to help went above and beyond my expectations. He even implemented some custom optimizations for my store. If you're scrolling through the app store, deliberating over which speed optimization app to choose – stop right here. With blazing fast improvements and stellar support, you've got all you need. Full five stars from me!

There were some minor issues in the beginning, but George handled them promptly and efficiently. Considering this is a free app, the support is better than most premium apps. George went above and beyond to handle everything and together we managed to improve my website's PageSpeed to an all time high score, now passing all Core Web Vitals metrics. I recommend this app to anyone in need of improving their PageSpeed score in a safe and efficient way. Be sure that you're in good hands with George and Thunder app.
