Hi! We are looking to migrate to Shopify in October and have come across a lot of varying ideas as to what apps/integrations slow sites down or affect site performance. Below is a list of apps we were looking at using, can anyone tell us which are the clunkiest/which we should definitely stay away from? Is the below too many to add to a site for integrations and apps? HELP!
App OR Integration OR use Native HTML functionality available:
You can check your site with Google PageSpeed Insight: https://developers.google.com/speed/pagespeed/insights/
Usually, slow sites are caused by blocking js files added by 3rd party apps. After You remove them, the speed will be improved. Repeated or unused apps should be removed.
Having only a few apps installed can cause a severe impact to page speed - we found that even installing a few apps caused some pages to slow down by as much as 6 seconds. Apps cause major issues - always use custom development when possible for your site features, over-reliance on apps is a guaranteed way to kill your site speed!

A few suggestions:
Since app content typically runs on every page whether it's used or not, eliminating apps that you don't need is guaranteed to have an impact to help improve page speed on pages across the site.
