I came across Ko-Fi by accident. I happened to click a link on the twitter account of someone I follow and discovered it.
Ko-Fi is a different sort of model for supporting an artist’s or writer’s work. Unlike, Patreon, I don’t have to constantly create new content that only my Patreon subscribers can see.
With Ko-Fi, people can make a one time donation and it’s always $3 USD or about the price of a cup of coffee. You can donate once or as many times as you want. Pretty simple.
