Does Gumroad have a monthly fee?

I'm curious to know if Gumroad imposes any monthly fees on its users. As a platform that facilitates the sale of digital products, it's important for creators and sellers to understand all the associated costs. So, does Gumroad charge a monthly subscription fee, or is it a pay-as-you-go model where fees are only incurred when transactions occur? Clarifying this point would help potential users make an informed decision about whether Gumroad is the right platform for their needs.
