Payhip

Payhip's free plan is a real starting point, not a stripped demo, letting a creator list and sell digital products, courses, and memberships immediately, with Payhip taking 5% of each sale plus card processing until the creator upgrades. The Plus plan at $29 a month drops that to 2%, and Pro at $99 removes it entirely, giving a seller a clear, gradual path as revenue grows rather than an all-or-nothing jump to a paid plan.

One feature that stands out is native support for selling software license keys, useful for a developer or small software business rather than just course creators. Compared with Sellfy's flat-fee-free tiers, Payhip's percentage-based free plan suits someone testing whether a product sells at all before paying anything, while a creator with steady volume will do better moving to Pro once the fee savings outweigh the monthly cost.
