Where each one falls short

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

Microsoft Azure API Management

  • Prices are not shown on the pricing page itself; every tier renders as a placeholder and routes to the calculator or sales
  • Two parallel generations of tiers, classic and v2, so the choice is which lineage before which size
  • The Developer tier is explicitly not for production
  • Self-hosted gateways and workspace gateways are charged separately from the service

Tuum

  • It is a smaller, younger company than Mambu, so it has fewer live reference deployments and a shorter track record to evaluate risk against.
  • The 2022-era rebrand from Modularbank to Tuum means older funding records, case studies and press coverage appear under a different name, complicating due diligence for anyone unaware of the change.
  • Pricing is entirely unpublished, requiring a sales conversation to budget against competing composable core vendors.
  • Its geographic expansion into DACH and the Middle East is comparatively recent, so support depth and local regulatory expertise in those markets are less proven than in its home Baltic and Nordic base.
  • As with any core banking platform, choosing Tuum is a multi-year infrastructure commitment; switching cores after implementation is a major undertaking regardless of how modular the initial adoption was.
