The short version

  • Only Pusher has a free tier, so it costs nothing to try first.
  • Each has a real cost: Mambu pricing is entirely unpublished, and as subscription and usage-based fees scale with a bank's book of business, total cost at scale is hard to forecast before a detailed vendor conversation.; Pusher the free Sandbox plan is capped at 100 concurrent connections, which is quickly outgrown by production apps.
  • They diverge on capability: Mambu covers Composable engine architecture, Pusher covers Pub/sub channels.
  • 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.

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  • Pricing is entirely unpublished, and as subscription and usage-based fees scale with a bank's book of business, total cost at scale is hard to forecast before a detailed vendor conversation.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.

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.
