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!
