I like that there are constantly updates and Thunder Page Speed is constantly monitoring my website performance and autonomously doing optimizations when needed. Thanks for the great support!

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.

Been using this for a while, reduces your dalays and helps the site load faster, had a minor inconvenience at first of website glitching out, but the staff were quick on the ball and fixed it

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!

Nothing but good things to say about my experience with the Thunder page speed team. They promptly helped me out and fixed many issues that were slowing down my store, these were issues made by other apps and "specialists". Thanks again can wholeheartedly reccomend!

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.
