“The problem with Figma plugins is that the market is really not that big. If you look closely on the Figma marketplace, you can probably tell pretty fast there are relatively few plugins making money. There are some UI kits listed where, if you divide the views/uses between 100 to get a sense of the revenue, you end up with something like €20-€400 which is frankly not worth the effort.”
I don’t think that’s necessarily true, and know that some creators make significantly more. That said, I wish it was easier to guesstimate the market size for the idea on the Figma marketplace. I love how Etsy shows the number of sales in every shop, and in combination with the number of ratings, it can give a rough estimate of the item’s success.
