The short version

  • Each has a real cost: Medusa the managed cloud meters four separate resources: edge requests, emails, compute hours and database storage; Mollie non-European cards cost 3.25% plus 20p against 1.20% plus 20p for UK domestic consumer cards, so a merchant with significant traffic from the US or Asia pays close to triple the domestic rate on that revenue.
  • They diverge on capability: Medusa covers Open source, Mollie covers Local payment methods.

Where each one falls short

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

Medusa

  • The managed cloud meters four separate resources: edge requests, emails, compute hours and database storage
  • The Develop plan at $29 a month applies a hard limit of 1,000 emails, so it stops rather than bills
  • Compute hours are capped at 600 on Develop and 800 on Launch
  • Edge request overage is $0.3 per million and storage $0.5 per GB month above the plan allowance
  • Background workers and priority support require the Scale plan at $299 a month

Mollie

  • Non-European cards cost 3.25% plus 20p against 1.20% plus 20p for UK domestic consumer cards, so a merchant with significant traffic from the US or Asia pays close to triple the domestic rate on that revenue.
  • Coverage is built around European methods, so if you expand into Latin America or Southeast Asia you will need a second processor and a second reconciliation process rather than extending Mollie.
  • The in-person Pro plan requires a one-year contract and charges 20 pounds a month per additional terminal, so a shop with four tills pays 80 pounds a month in terminal fees before any transaction cost.
  • Mollie offers no interchange-plus option publicly, so large merchants cannot see or benefit from falling interchange the way they could on a cost-plus contract with an acquirer.
  • The developer tooling and reporting are lighter than the largest processors, so finance teams that want detailed fee breakdowns or granular reconciliation exports often end up building that layer themselves.
