Pages just open quicker than they used to, customers have even mentioned it. Not much else to say, it does the job it promised and I havent had any issues.
— Inspire art
We switched themes last month and the load times on desktop got noticeably better after turning this on. I like that it keeps scanning and shrinking images even after the initial setup so I dont have to babysit it. would be nice if it sent a small alert whenever it makes a change behind the scenes.
— Trailpaw One
As someone who builds themes for clients I appreciate that it handles the javascript and css minification cleanly. The script deferral didnt break any of my custom code which was my big worry.
— Survival Top
been running it about two months now. The image compression is great, it picks up new product photos on its own without me touching anything. my GTmetrix numbers climbed nicely and the mobile side feels snappier than before. One thing the dashboard could explain what each setting actually does a bit better
— Neat Nest Vip
My store loads way faster now and thats honestly the only thing i wanted, so im happy
— casecraftco
this app helped speed up my store without manual changes. lazy load and caching are good features. sometimes results vary between pages and i had to double check settings, but still better than before.
— Clean Living Shop
crazyload improved my gtmetrix score and made pages load faster. automatic scanning for images is very helpful. sometimes loading the dashboard takes time and i saw a small typo, but features work fine.
— Work Day Supply Store
this app boosted my pagespeed score and made my store feel quicker. lazy load and js deferral works pretty well. sometimes changes took a bit to show and i had to refresh. still a solid tool for improving performance.
— Less-Ishliving
This app made a noticeable difference in pagespeed. Image compression runs in background and caching helps with new apps. I like not having to think about it. Took time to understand AI optimization and one toggle confused me. Still worth it for speed improvements.
— Welldesk Store
We installed Crazyload because our store was slow and it actually helped. Lazy loading works well and css js minification reduced load time. Sometimes preview looks odd before cache clears and the settings text has small typos. Overall its doing its job without much effort.
— Active Recovery Shop Biz
this app helped clean up our site speed issues. AI optimization adjusts things automatically and i dont have to tweak code. CSS minification works well. Interface feels cluttered and one setting reset once. Small annoyances. Speed gains are real though.
— Urban Pet Supply Space
Crazyload dropped our site load times quickly especially on mobile where we were losing most visitors. The app runs in the background and doesn’t need much attention after install, which is perfect for me since i’m busy with marketing.
— Meadow Light Co Online
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...
— Varialle
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...

Sometimes it’s a little confusing to see exactly what changed behind the scenes or which adjustment caused the biggest impact, especially when multiple things are optimized at once. but overall we clearly saw site load times drop after installing it. I also like that it works automatically in the background and doesn’t need constant attention or manual tweaking to keep things running well.
— Aivanaliving Store
Page load times dropped pretty fast after setup, especially on mobile which was our main issue before. the dashboard could be clearer and a bit more beginner-friendly, but once you understand it, the performance gains are definitely worth it and noticeable across the store.
— Solmist Home Biz
Love that i didnt need any tech skills to use this. Crazyload did most of the optimization for me and now pages load much faster even during high traffic times.
— Brightmill Studio Art
Nice tool for optimizing performance. sometimes I’m not totally sure what changed, but the speed gains speak for themselves and bounce rate dropped a bit.
