What they are

Ko-fi

Ko-fi is a monetization platform where creators accept one-time donations, sell digital products, and offer paid memberships directly from their audience. It suits artists, writers, podcasters, and indie developers who want a lightweight income layer without surrendering a cut of every transaction. Free to use with no monthly fee. Ko-fi takes 0% on tips and donations, and 5% on shop sales, memberships, and commissions. Ko-fi Gold removes the 5% fee, although payment processors still take their standard slice. The trade-off is a thinner feature set compared to dedicated membership or course platforms.

Substack

Substack is a publishing platform where writers host email newsletters and charge subscribers a recurring fee. Independent journalists, essayists, and niche experts use it to build direct audiences without relying on ad revenue. The platform handles payments, delivery, and a basic website automatically. Substack takes a 10% cut of paid subscription revenue on top of stripe fees, which becomes a real cost as an audience grows.
