I’ve tried a few speed optimizer apps before but honestly this one surprised me. After installing Thunder, I noticed a visible difference in how quickly my store loads - especially on mobile.

I tried few speed optimization apps before Thunder, but this one is definitely the one that gives you the most extensive data based insights into issues and which pages are slow! The automatic speed optimization are a lifesaver for a store that constantly makes changes on the website!

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.
