Where each one falls short

Documented limitations, not opinions. Every one is a constraint you would hit in normal use.

FastSpring

  • Pricing is not published and requires contacting sales for a quote, making cost comparison difficult upfront.
  • As a merchant-of-record, FastSpring takes on more control of the checkout and payment relationship than a pure payment gateway like Stripe.
  • Revenue share pricing can become more expensive than flat per-transaction gateway fees at very high volumes.
  • Primarily targeted at software/digital goods sellers, so it is less suited to physical product e-commerce.

MotherDuck

  • The free Lite plan caps compute at 10 hours per month, which limits it to light or hobbyist workloads.
  • Business plan usage charges on top of the $250/month base can make costs less predictable than flat-rate competitors.
  • There are no academic or non-profit discounts, unlike some competing data platforms.
  • Annual billing requires going through a sales conversation rather than a self-serve toggle.
