Thunder Page Speed Optimizer

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.

georgi is the best

Okay so my service earlier with them wasnt that good, but there customer staff actually contacted me and he even go 1 step ahead for optimizing the website. current i am testing the optimization, i will for sure update about it.... but for the customer Support, and the help they have done..... It was great

In principle it looks an impressive good speed optimizer, but I will let you know in a few days. Many thanks

bad support and speed of site still not good

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! ^^

App is good and Georgi is quite cooperative as a support person. Highly Recomended

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.

This app is fantastic! My website’s loading speed improved instantly, boosting user engagement and SEO. The interface is user-friendly, and it provides clear insights and actionable fixes, plus the support team is excellent. A must-have for anyone looking to optimize their site!

Excellent Support, Georgi quickly understand the issue & solved in a few minutes. Totally recommended specially because of the support

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

Great help from George today with a bit of code my store needed. Much appreciated for your time, and a valuable app to have boosting my site. Thanks!

Great customer service! Highly recommend. We had a issue where our dashboard wasn't updating properly. George was super helpful and went above and beyond to get us up and running asap.

It is very easy to use and the customer service is very honest. I am very satisfied

Fantastic App, and the support received has been priceless. recommended top all

Theme editor stopped working after was removed. Site editor is messed badly.

Great app that was easy to set up and improved my site speed significantly without much trouble. But what sets them apart is their support: I was able to speak directly with the owner right off the bat, who was very responsive, and he even ended up helping me solve a problem that wasn't even related to his app! Having a real person to help me with my unique problem is important to me as a sole business operator who doesn't have a tech background, and it's definitely kept me from looking at other page speed apps!
