Rocket Page Speed Optimizer
The reviews are sharply mixed, but the dominant pattern is that the app can significantly improve page speed, Core Web Vitals, and Google/Shopify performance scores for many merchants. Positive reviews repeatedly mention large jumps in mobile and desktop scores, better LCP/CWV results, quick setup, and support that is often described as fast, friendly, and effective when it responds. Several users say the app delivered results they could not achieve with other speed tools, and some credit it with improving SEO-related metrics and overall site performance. On the negative side, a substantial number of reviewers report that the app is unstable, overly invasive, or ineffective over time. Common complaints include theme breakage, conflicts with other apps, manual changes that cause site issues, and speed gains that fade unless the app is repeatedly tweaked. Support is the biggest recurring pain point in negative reviews: some merchants say emails and tickets go unanswered for days or months, or that support stops responding after problems arise. A few reviewers also criticize the pricing model, saying the app seems to do little after installation, and some warn that it can damage code, schema, or site functionality.

Kinda works, but its highly inflexible (breaks other apps with no way of whitelisting them), the implementation is very weird, it updates your theme daily (or more) to change an expiry date. If this date is reached it wont work anymore, as a way to break it when you uninstall it. Generally this works completely without a server, so a one-time payment would make more sense. Instead they have a monthly fee for doing basically nothing after installing, other than messing with your theme. Customer service also never answered my question for a way to whitelist scripts. Better use another app, that ain't it.
I've been using this app for years, and it has improved my CWV scores. The customer service has been responsive and helpful as well.
Non migliora niente ! Solo perdita di soldi !
Hi, We're sorry that the app did not provide sufficient value for you. Please reach out to our support to receive a full refund.
I have been using this for 5 months. The concept is great, but the implementation of this is trickier than meets the eye. There are plenty of issues with the implementation and support side. It appears to work, but after a while more and more issues parts of the website/theme will break. This is only caused issues with breaking my theme in various areas that takes a long time to find out. I have been in contact with the support team multiple times, and after it repeatedly breaks the website, they stopped responding to emails. I have been left without support from the team and will no longer use this.
We installed the app and were in contact with a member of their team. He noticed that we were using other plug-ins and proceeded with manual customization. Apparently, no testing was conducted after making these changes. As a result, our entire front page became non-functional, and product images failed to load. This issue cost us a full day of revenue. Completely unacceptable.
