Where each one falls short

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

Castmagic

  • Free plan limited to 3 files per month
  • Pricing based on audio hours consumed
  • Not a full podcast hosting solution

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.
