So you walked out of the free carpentry store holding Linux, a Go compiler, Git, etc. and now you're looking to build stuff to sell to other carpenters! Non-carpenters don't need microservice frameworks or app platforms. Plus carpenters know they can usually get the stuff for free anyway - they were just in the same store as you!

Have a think about the relative sizes of the carpenter market vs. the non-carpenter market.

0.5% of humans are devs, but 70% of humans have internet. 70-90% of internet users have made an online purchase. (I assume these AI slop answers are at least in the ballpark)

(Anyway I really don't have a head for business, so don't take my advice. I just like programming on and off the clock and I get a salary for it)
