The short version

  • Only Postman has a free tier, so it costs nothing to try first.
  • Each has a real cost: Postman free plan limited to single user as of March 1, 2026, making it unsuitable for teams without paid plans; 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.
  • They diverge on capability: Postman covers API client, Swan covers Embedded business accounts.
  • Prices and features above were last checked on 1 September 2026.

Swan

  • A company wanting SEPA payment initiation embedded directly into its own productnot Postman
  • A European fintech wanting to avoid a six-figure setup fee and long lock-in typical of legacy banking-as-a-service dealsnot Postman

Where each one falls short

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

Postman

  • Free plan limited to single user as of March 1, 2026, making it unsuitable for teams without paid plans
  • Only 25 collection runs per month and 1,000 API calls/month on free tier
  • Removed local-only Scratch Pad mode in 2023, forcing cloud account creation and sync
  • Requires Postman account and internet connection for most features
  • Cloud-first architecture with mandatory syncing to Postman's cloud servers
  • No CI/CD integration or advanced security features on free plan

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.
