Where each one falls short

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

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.
