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  • Pricing is entirely unpublished, and as subscription and usage-based fees scale with a bank's book of business, total cost at scale is hard to forecast before a detailed vendor conversation.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

Stoplight

  • The free plan allows one project and one user
  • Private projects, multi branch support and custom domains start at the Startup plan, $113 a month billed annually
  • SSO and shared style guides are Pro Team only, at $362 a month billed annually
  • Seats beyond each plan's allowance are $11 to $27 each per month depending on tier and billing period
