Where each one falls short

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

Paddle

  • Paddle charges 5% plus 50 cents on every checkout transaction, which is well above a bare payment processor rate
  • The 50 cent fixed component falls heavily on low value sales, and products under $10 require custom pricing agreed with sales
  • Invoicing is not covered by the published rate and requires custom pricing
  • As a merchant of record Paddle sits between the seller and the customer, so payouts and tax handling run through Paddle rather than the seller's own processor

Redis

  • Licensing changed from BSD to AGPL in 2025, impacting open-source usage
  • All data must fit in memory, limiting scalability to available RAM
  • No built-in support for multi-tenancy
  • Limited transaction support compared to traditional databases
