The short version

  • Only Gravitee has a free tier, so it costs nothing to try first.
  • Each has a real cost: Gravitee the entry paid API management tier is $2,500 a month and includes a single production gateway; Sila no pricing is published, so you cannot compare Sila against Moov or Dwolla without entering two sales processes, and small programmes frequently find the monthly minimum dominates their cost at low volume.
  • They diverge on capability: Gravitee covers API Gateway, Sila covers ACH origination.
  • Prices and features above were last checked on 31 August 2026.

Where each one falls short

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

Gravitee

  • The entry paid API management tier is $2,500 a month and includes a single production gateway
  • Event management is priced separately, starting at $1,250 a month for the Comet tier
  • Tiers are gated on gateway and broker counts, so scaling horizontally means moving tier rather than paying incrementally
  • Data logging masking and other enterprise features are withheld from the lowest paid tier
  • 24/7 support requires the top Universe tier

Sila

  • No pricing is published, so you cannot compare Sila against Moov or Dwolla without entering two sales processes, and small programmes frequently find the monthly minimum dominates their cost at low volume.
  • Sila is materially smaller and less well capitalised than the banking-as-a-service names it competes with, which matters because your customer funds and your payment rails depend on the vendor still trading in three years.
  • The sponsor bank behind your programme determines what you can offer and how fast you can change it, and bank partnerships in this sector have been reshuffled repeatedly since 2023, so a bank change during your contract is a realistic risk rather than a theoretical one.
  • Coverage is United States only, so any product with cross-border ambitions needs a second payments vendor and a second reconciliation process from the outset.
  • Onboarding involves compliance diligence on your own programme, and teams routinely underestimate this, with weeks lost between signing and first live transaction while policies, flow of funds diagrams and BSA arrangements are reviewed.
