Maybe I missed it, but your landing page could use a couple of example stores built with your tool, and a better description of the features/personalisation options.
It looks very clean, well done. What I meant though is to have a link (or some pictures) on your main page so that people see what the result looks like before having to sign on.
We have an example store here (checkout isn’t configured for the example): https://example.spry.store/
You can currently customize the store name and subdomain. Custom domains is something we’ve considered. We’re open to other ideas!
