The Shopify Exchange is a marketplace for buying and selling e-commerce businesses built on Shopify’s platform.
Browsing inventory on the Exchange is a pretty bad experience, but luckily, Shopify exposes an endpoint that has richer listing data.
I collected some data from the exchange on 2/20/2020 and 4/10/2020, wrote about it here, and shared the CSVs in this repo.
