So pretty much like the title says. There are apps and extensions that let you spy on Shopify stores such as Koala Inspector, but these extensions do not work on other CMS I believe (from what I've tried). I even searched how to spy on my competitor for other CMSs and nothing was as powerful as spying on Shopify...

... which made me wonder, should I then avoid Shopify for my online store to make sure my competitors don't spy on me?

Thank you
