Real pricing and fees
Ko-fi takes 0% on tips and 5% on shop sales, memberships and commissions on the free plan; Ko-fi Gold costs USD 12/month and removes that 5%. Stripe or PayPal processing (roughly 2.9% + USD 0.30) is charged on top in every case, because it is the processor's fee and no platform can waive it. Publica Now charges 20% + USD 0.30 per paid transaction with processing included. On a pure fee comparison Ko-fi is clearly cheaper, and at any meaningful volume Ko-fi Gold is cheaper still.
