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

Lithic

Pricing is entirely undisclosed, so a company cannot compare total cost against Marqeta, Galileo or Highnote without a sales conversation.
Choosing Processor Client mode still leaves the company responsible for holding its own issuing licence and managing the regulatory relationship, which is a substantial undertaking many teams underestimate.
As with any card infrastructure provider, an outage or network issue at Lithic becomes a direct outage for every card programme built on it, and a customer has limited visibility into root cause during an incident.
Building a card programme on API infrastructure requires real engineering investment; it is not a plug-and-play product for a non-technical team.
Switching card infrastructure providers after launch is a major undertaking involving card reissuance and programme migration, so the initial choice carries lasting lock-in.
