House of Léon review for Rebuy Personalization Engine

Nov. 14, 2022

A major part of the reason for upgrading to Shopify Plus was for Rebuy. We were told that the app wouldn't slow down our site. After working with the Rebuy team (great people and very helpful which is why I'm giving 3 stars) to set up our widgets and data sources we set Rebuy live. Immediately our site speed plummeted (lighthouse score went from 85 to 30) which in turn sank our conversion rate and made our ads more expensive to run. We were told Rebuy runs after our pages load, but I'm pretty sure that's not true. After about 2 weeks we realized what was going on and uninstalled the app. After another week of scrambling we realized that our site was littered with rebuy code we decided to revert to an old theme out of desperation. After reading other reviews I've only found a few other companies that had this problem, so maybe it's unique to a few. That being said, although we feel we were misled, we have been in communication with the Rebuy dev team who said hey are working on optimizing the code even more. We will try Rebuy again after that happens, but we will be way way more cautious this time around and have a back-up theme in place just in case.
