The short version

  • Only DuckDB has a free tier, so it costs nothing to try first.
  • Each has a real cost: DuckDB client-server setup remains in beta and not recommended for production distributed scenarios; FastSpring pricing is not published and requires contacting sales for a quote, making cost comparison difficult upfront.
  • They diverge on capability: DuckDB covers In-process Execution, FastSpring covers Global online payments.

Where each one falls short

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

DuckDB

  • Client-server setup remains in beta and not recommended for production distributed scenarios

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.
