Thunder Page Speed Optimizer

Probably one of the best app if you're looking to speed up your shopify theme, it helped us increase our score by 21 points!

I could not be more satisfied with the app and, of course, the perfect support. My website had an issue, and Georgi fixed it manually. Awesome experience

wow, how is this free. Increased my sites speed with multiple seconds. I highly recommend this app to anyone its amazing

App Does what is says. It raised my speed score from 55 to 73 quickly. The app took about 10 minutes to finish. For the negative reviews, It seems like it creates a new copy of your site so any issues should be easily fixed by simply deleting the thunder version and publishing the original again. I Can't say anything negative about my experience with this app, you need to install this app. And the price can't be beat.

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.

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.
