The short version

  • Only Gravitee has a free tier, so it costs nothing to try first.
  • Each has a real cost: Gravitee the entry paid API management tier is $2,500 a month and includes a single production gateway; Mambu pricing is entirely unpublished, and as subscription and usage-based fees scale with a bank's book of business, total cost at scale is hard to forecast before a detailed vendor conversation.
  • They diverge on capability: Gravitee covers API Gateway, Mambu covers Composable engine architecture.
  • 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.

Gravitee

  • The entry paid API management tier is $2,500 a month and includes a single production gateway
  • Event management is priced separately, starting at $1,250 a month for the Comet tier
  • Tiers are gated on gateway and broker counts, so scaling horizontally means moving tier rather than paying incrementally
  • Data logging masking and other enterprise features are withheld from the lowest paid tier
  • 24/7 support requires the top Universe tier

Mambu

  • Pricing is entirely unpublished, and as subscription and usage-based fees scale with a bank's book of business, total cost at scale is hard to forecast before a detailed vendor conversation.
  • A core banking implementation is a multi-year, high-switching-cost commitment regardless of vendor, and Mambu is no exception; a wrong initial configuration choice is expensive to unwind.
  • Composability is a genuine strength but also means more integration and configuration decisions fall to the bank's own team or system integrator, versus a more opinionated, less flexible fixed-core alternative.
  • As cloud-hosted core banking infrastructure, a bank is trusting Mambu's own uptime and security posture for its most business-critical system, concentrating operational risk in one vendor relationship.
  • Newer entrants such as Thought Machine and 10x Banking compete directly on similar composable positioning, so Mambu's tenure advantage is real but narrowing as competitors mature.
