Thunder Page Speed Optimizer

The app is great and the developer is very willing to help you fix issues with your store speed.

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.

I can’t open the operation page all the time, and there is no reply to the email contact. There is no reply after contacting for three times in a row. Extremely bad service

I reached out to George once i installed the app to see what he could do for our store - it took a while for a response due to technical issues he was having with shopify which are now resolved. He has since got back to me and offered his skills to help improve our stores score overall and asap

I hate giving poor reviews, but this app simply isn't working at all. At first I only saw a blank screen when opening the app. Ok, the app support responded quite fast to solve the issue and confirmed it was a bug on their/Shopifys side. But then the optimization page just freezed and nothing happened. I didn't see any kind of progress on the dashboard or in the history tab. And now I'm back to seeing the blank screen. Very frustrating and what's even worse, the app support disappeared and is not replying to my emails anymore.

Ran into an issue (no fault of the plugin) where our mega menu was not showing. Emailed support, spoke to Gerogi who could not have been better if he tried! Within a couple of emails he had been granted access to our theme, resolved the issue and gotten the plugin working to it's full potential! Went from an F with 23% peformance all the way to a D with 61% which is almost a 3X in performance!! Could not recommend this plugin enough to anyone! If you want the best for speed optimisations, you've found it here!

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!

Increased our speed. We got some help from the team, Georgi, and felt like he took great care of us and made things work great!

Critical css, image resize not working on my website. Not sure if prefetching works. Within the code of loading bar and therefor sort of hidden, a link to https://www.w3.org/ creates "the largest contentful element" with error, read by website speed anaylizers also as an error, somehow registers for a higher speed. The only true benefit using this app was compressing the css file and nothing more.

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.

WHY ARE PEOPLE WRITING NEGATIVE THINGS ABOUT THIS APP It is literally amazing and the guy isn't charging a dime. Thank you Enigma Apps saw a great improvement in site speed and pagespeed insights score.

Worked on both of my shops. Perfect app, that improves the speed significantly! Take a chance as it is available for free ;)

Die App hat uns wirklich geholfen, die Ladegeschwindigkeit in der mobilen Version zu erhöhen. Wir hatten dafür ein Angebot eines Anbieters in Höhe von 300 $. Hier kam der Service kostenlos. Der Support könnte besser erreichbar sein und auch würde ich mir Empfehlungen wünschen, wie oft man das "Optimize"-Programm machen sollte. Man muss sich darüber im Klaren sein, dass die Alt-Texte der Bilder nach der Optimierung verschwinden, wenn sie nicht über die Datenbank hochgeladen wurden. Aber für uns in Ordnung, da das nicht zu aufwendig in der Wiederherstellung ist.

Final review of this app. Read the reviews of the great service this app has provided. I didnt see it. Spent days emailing with no reply. Then an "I'm sorry for the late reply" email only to never reply to emails or support again. The app seems nice and I hate to leave a poor review of a free app but if you offer a product it would be nice to respond to support. Even if it is to say I'm sorry this will not be a fit for you. Wasted a week on this with no luck. I would recommend skipping this app.

Wow, I've used a lot of apps to speed up my store. Half of them seem to do the opposite. Thunder is really very good. Had a little glitch in setup and Georgi from the support was fast, efficient and friendly. 5 stars all round from me :)

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.

Amazing app! Super easy to set up, everything was automated and really increased the load speed of our store!

They have perfect support. My website had issue but they fixed it quickly. I love this app and this support.

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

Very helpfull and easy to install and use, page speed speed up with thunder. I ask for something and George respond fast and honest. Keep up this
