Let's be fair: Ko-fi's 0% platform fee on tips is genuinely generous and genuinely real - every dollar of a tip goes straight to your own PayPal or Stripe, Ko-fi never touches it, and it takes minutes to set up with no company. For artists, writers and streamers running a tip jar, it's excellent and hard to beat. But Ko-fi is a hosted page at ko-fi.com/yourname, not payment infrastructure you embed in your own app - and once you move past tips into memberships, a shop or commissions, a 5% cut and processing fees appear. This isn't a takedown; it's where the two tools stop overlapping. Everything below is from Ko-fi's own help pages and public reviews (July 2026).
| Scenario (recurring) | Ko-fi free plan | Effective | paas.build (3.9% flat) |
|---|---|---|---|
| $9 membership | $0.45 fee + ~$0.56 processing | ~11.3% | $0.35 = 3.9% |
| $29 membership | $1.45 fee + ~$1.14 processing | ~8.9% | $1.13 = 3.9% |
On tips and donations, yes - the free plan takes 0% platform fee and money goes straight to your PayPal or Stripe. But the free plan takes 5% on memberships, shop sales and commissions, and payment processing (~2.9% + $0.30 via PayPal or Stripe) always applies on top. To remove the 5% you need Ko-fi Gold, reported at about $12/month for new sign-ups. Sources: help.ko-fi.com and third-party reviews.
No - and that is a real strength. Ko-fi is not the merchant of record and does not process payments; funds transfer directly and immediately into your own PayPal or Stripe account. The trade-off is that you own the tax, VAT, refunds and disputes yourself, because Ko-fi is a facilitator, not a Merchant of Record.
Not really. Ko-fi is a hosted page at ko-fi.com/yourname with a donate button and widget - great for a tip jar, but it is not a branded checkout or subscription-billing API you build into your own product on your own domain. For an AI-app subscription billed inside your product, paas.build gives you embeddable branded checkout and recurring billing, flat 3.9%, and you stay the merchant.
If you want a tip jar or light creator page, Ko-fi's 0% on tips is hard to beat. If you are billing an AI app or SaaS subscription inside your own product and want your brand on the checkout: paas.build - live the same day via progressive KYB, flat 3.9% with no fixed or payout fee, embeddable checkout and subscriptions, no company needed, and you stay the merchant.
