This really an amazing super app which can significantly speed your store in just little mins.

I recommend everyone install the app,in addition to their amazing customer support.

Thank you thunder to help speed up my store easily.

Amazing app. Am the designer / owner of ourhatsdeservebetter.com I was stuck with poor performance linked to technical issues I could not deal with. 18% overall improvement on my pages, home, collections, products, ..., measured on PageSpeed Insights and lighthouse, both on mobile and desktop view, without impact on site visual quality. So easy to use that I just run it without the need to require technical support. And it is FREE!... I don't understand the business model but I love it!

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.

Great app and support. I had some issues when I optimized the theme, and Georgi from support was amazing! He really helped me, and now everything works as it should. My store mobile speed went from 39 to 57 which is not bad for a free app!

The speed score of my store was below 30 and after installing and waiting to see some results, now the speed is 54, I can honestly say that this app is worth it, and I highly recommend it to anyone looking for an app like this one.

What an amazing experience with this app, highly recommended. There is no risk trying, you're guided throughout the process, and you test before deploying live, so you know it works properly. I'm just amazed how the whole thing went. Feels faster and I can just say thank you!

App functionality is perfect. Has many interesting features. They were some bugs which were frustrating but the app developer helped us throughout the process and helped resolve the issue.

100% for support!

This app gave great results from my homepage, raising the score from 47 to 77.

I had a few doubts, But the Dev, George, gave me great advice on what I should be doing.

Was all very simple in the end.

Thanks George

This app is amazing! It has really improved the speed of my website. I really recommend to everyone who is having problems with their store speed!
