Thunder Page Speed Optimizer

Really impressed with Thunder Page Speed Optimizer. The setup was quick and easy, and I noticed an improvement in my store’s loading speed without needing to make complicated technical changes. The app is simple to use and the support team is also very helpful. Definitely a useful app for Shopify store owners looking to improve their store performance.

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!

Thunder made a noticeable difference to our store speed. The setup was super easy, and we didn't need to make complicated technical changes. Our pages load much faster now, which has improved the overall shopping experience

Great app for improving Shopify store speed! It’s easy to set up and the optimization features are simple to use. I noticed a smoother browsing experience after using it, and the interface is clean and user-friendly. Highly recommended!

Overall, it’s a useful option for stores looking to add upsells without much complexity.

Good experience so far. It improved our site speed and helped clean up some performance issues. It’s not 100% ‘set and forget’—we needed a bit of support—but the team was quick and helpful. Overall very happy with the results.

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.

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! ^^
