The short version

  • Each has a real cost: Portkey the free Developer tier records only 10,000 logs per month with 3 day log retention; the $49 per month Production tier raises that to 100,000 logs with $9 per additional 100,000 requests, as of August 2026.; 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.

Where each one falls short

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

Portkey

  • The free Developer tier records only 10,000 logs per month with 3 day log retention; the $49 per month Production tier raises that to 100,000 logs with $9 per additional 100,000 requests, as of August 2026.

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  • Pricing is entirely unpublished, requiring a sales conversation to budget against competing composable core vendors.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.
