  • Each has a real cost: Pusher the free Sandbox plan is capped at 100 concurrent connections, which is quickly outgrown by production apps.; 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.
  • They diverge on capability: Pusher covers Pub/sub channels, Tuum covers Modular product structure.
  • Prices and features above were last checked on 1 September 2026.

Where each one falls short

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

Pusher

  • The free Sandbox plan is capped at 100 concurrent connections, which is quickly outgrown by production apps.
  • Pricing jumps sharply between tiers (e.g. $49 to $99 to $299), leaving few options for teams with moderate but growing usage.
  • Priority support with faster response times costs an additional $3,000/month on top of plan pricing.

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  • Pricing is entirely unpublished, requiring a sales conversation to budget against competing composable core vendors.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