Where each one falls short

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

Swan

  • Its regulatory base and strongest local account coverage are French and European, so companies needing US, UK-post-Brexit-specific, or broader global banking-as-a-service need an additional provider.
  • Pricing is described only philosophically (usage-based, no big setup fee) rather than published as an actual rate card, so a company still needs a sales conversation to get real numbers.
  • Embedding banking features into a product is a substantial compliance and design undertaking regardless of the vendor, and Swan handling the licence does not remove a platform's own KYC, AML and customer support obligations for the accounts it offers.
  • As a comparatively young, single-country-licensed e-money institution, its balance sheet and regulatory standing carry more concentration risk than a banking-as-a-service offering backed by an established, multi-jurisdiction bank.
  • Local account depth is explicitly limited to France, Germany and Spain, so a platform needing native local accounts in other European countries may find coverage thinner than expected.

Treblle

  • No free tier is offered; the entry-level Core plan starts at $233/month billed yearly.
  • Growth and Enterprise pricing is custom and not published, requiring a sales conversation to budget.
  • Core plan is limited to 1 workspace and only 30 days of data retention.
  • SSO and on-prem/BYO cloud deployment are reserved for the top Enterprise tier.
