The short version

Only curl has a free tier, so it costs nothing to try first.
Each has a real cost: curl open-source with no vendor pricing: curl is free and open-source under GPL 3.0; no subscription or licensing costs apply; Mambu pricing is entirely unpublished, and as subscription and usage-based fees scale with a bank's book of business, total cost at scale is hard to forecast before a detailed vendor conversation.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: curl covers HTTP/HTTPS, Mambu covers Composable engine architecture.

Where each one falls short

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

curl

Open-source with no vendor pricing: curl is free and open-source under GPL 3.0; no subscription or licensing costs apply
Commercial support costs hidden: site references 'commercial support available' but pricing is not detailed or accessible from homepage
No SaaS model: curl is a command-line tool and library; costs are limited to optional commercial support contracts (pricing unknown)
Self-support burden: free software means customers rely on community forums or undisclosed commercial support pricing

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Pricing is entirely unpublished, and as subscription and usage-based fees scale with a bank's book of business, total cost at scale is hard to forecast before a detailed vendor conversation.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