As our product catalog grew, site speed started becoming more of an issue, particularly with all the images. This has helped cut down some of that extra weight, and the pages definitely feel faster now. I’d appreciate more detailed reporting about exactly what was optimized. Having more control over which optimizations are enabled or disabled would also be useful.

We have a pretty large catalog with a lot of product images, so keeping the site fast was becoming a bit of a challenge. This has helped by automatically compressing new images and making the pages feel lighter on both desktop and mobile. Our speed test numbers improved too. The dashboard wasn’t completely obvious to me at first, and I had to check one of the settings before making a change, but o...

The fact that most of the image optimization happens in the background is really convenient. I can actually feel the difference when browsing the store, and our speed scores have improved since we started using it.

After having this running for a while, the store feels quicker when I move from one page to another. It’s also nice not having to manually go through our images all the time. One less thing on my to-do list.

Our mobile site was definitely slower than we wanted, so I installed this mainly to see if it could help. There’s been a noticeable improvement, and I like that image compression runs in the background without me having to do anything. I’d like to see more explanation around some of the optimizations, but overall it’s been working well.
— Velvetritual Health
Really simple to set up and we noticed our store loading faster almost immediately. So far, it’s been doing exactly what we needed.
— Bloomthread
We knew our store needed some speed improvements but kept putting it off because I assumed it would involve a lot of technical work. This made the process much easier. Images are compressed automatically, the site feels faster on mobile, and our PageSpeed results have improved. It also handles new content without me having to constantly go back and check things. I did find some of the technical wo...

Our product pages are noticeably quicker, especially when checking them from a phone. The automatic image compression is probably my favorite feature because there’s nothing extra I need to manage once it’s set up.
— Pawprovisions Art
Mobile was the main reason we tried this, and I could tell there was a difference pretty quickly. Images seem to load more efficiently, the site feels less heavy, and our speed scores have gone up as well. I also like that new images are handled automatically, so I don’t have to keep checking them myself. A few more settings would be nice, but overall it’s been really helpful.
— Pure Vessel Tech
Definitely noticed an improvement in loading speed after setting this up. The store feels a lot more responsive than it did before.
— Barkwellsupply Shop
Bounce rate on product pages came down about 9% over the first month, cant prove it was all this but the timing lines up. Also nice that when we add a new app it gets handled without me poking at anything. Would like the history to go back further than a week, and the docs could use work.

Instalei o aplicativo mas ele além de deixar meu site ainda mais lento, tirou a minha página de Checkout, perdi várias vendas em menos de 24 horas, uma lástima. A sorte é que eu fiz um backup do meu tema e apenas troquei, porque o app estragou bastante o tema em que foi instalado. Pessoal da Crazy, vocês são Crazy mesmo, pois assim acabam com a vida dos lojistas, esse aplicativo deve passar por r...

Terrível, não melhorou desempenho e quando desinstalei, o app não removeu todos os códigos após desinstalação. Ele ataca o head do theme.liquid e altera sua estrutura de menus e outros... Me gerou uma grande perda de tempo tendo que restaurar versões para corrigir.
— Desestressar
Don't download this app without a backup for your current theme. This app crashed my site completely. Very devastating experience, especially after hitting #1 on search results on Google.
— NECTAR NAPKINS
Les commentaires sont faux, cette foutue application a réussi à faire chuter le score de mon thème (sauvegarde/duplication incluse), je ne sais même pas comment c'est possible ! Je ne peux pas mettre de capture dans l'avis, mais je suis passé de 89 de performance (je cherchais juste à obtenir les derniers points manquants) à 13 et 45 dans les meilleures analyses. Le pire, c'est que j'avais dupliq...

Switched from another speed app that left junk code everywhere. This one stayed out of my theme files completely. Desktop side is quick now, my agency noticed before i even told them and they dont miss much.

Ok so background, we run a multitools store and traffic is mostly phones. Our PageSpeed number sat at 31 for like a year, its 74 now, my partner didnt beleive me and made me screenshot it. Clicking betwen collections feels instant which i think is the preload thing. The guy who onboarded us was patient with my questions. It fights a little with our page builder so that could be smoother.
— Pocketforge Online
I dont normally leave these. Ran it on our store for two weeks, load times dropped and thats the only reason im typing this out. Good enough.
— BabyHugy
My homepage has like thirty photos on it because i sell kitchen ware and people want to SEE the Kitchen Ware. Used to take forever. Now the ones further down wait until you scroll which apparently is the whole trick. The dashboard doesnt talk down to you either, i understood most of it. Wish the price scaled better for tiny shops though.
— Saltedwave Shop
Been doing Shopify builds for six years so i went in skeptical. The deferral logic didnt break my custom sections which honestly surprised me. GTmetrix went from C to A on the collection pages, and the third party scripts we had piling up finally get cached instead of blocking render. Minification is solid. Two asks: let me exclude individual scripts from the UI, and give us a preview mode before...
