Where each one falls short

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

Aiia

  • It is now part of Mastercard rather than an independent company, so a business specifically wanting to avoid card network dependency in its banking infrastructure no longer gets that separation by choosing Aiia.
  • Pricing is not published and requires engaging Mastercard's open finance sales process, which can be a heavier sales motion than dealing with a smaller independent open banking provider.
  • Its strongest bank coverage remains concentrated in the Nordics and Northern Europe, so companies needing dense coverage in Southern or Eastern Europe should verify current bank connectivity before committing.
  • Brand confusion is real: developer documentation, login portals and older case studies still reference "Aiia" while newer Mastercard material refers to "Mastercard Open Banking," and a company researching either name in isolation may miss half the relevant material.
  • As with any open banking platform, reliability still depends on the consistency of the underlying banks' own APIs, which is a systemic industry issue rather than something Aiia specifically controls.

Boomi API Management

  • No public pricing available; consultative sales model requires direct contact with sales
  • Pricing described as flexible for SMBs to enterprise but not specified
