The short version

  • Only Galileo has a free tier, so it costs nothing to try first.
  • Each has a real cost: Galileo the free plan is limited to 5,000 traces per month, which is quickly outgrown by production workloads.; Marqeta you still need a sponsor bank and a BIN, so the timeline and compliance burden of launching are set by a bank you must separately court and satisfy.
  • They diverge on capability: Galileo covers Pre-built evaluations, Marqeta covers Just-in-time funding.
  • 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.

Galileo

  • The free plan is limited to 5,000 traces per month, which is quickly outgrown by production workloads.
  • Real-time guardrails and unlimited trace capacity are reserved for the custom-priced Enterprise tier.
  • Pro plan pricing scales with trace volume, so costs can grow unpredictably as usage increases.
  • On-premises deployment requires an Enterprise contract rather than being available self-serve.

Marqeta

  • You still need a sponsor bank and a BIN, so the timeline and compliance burden of launching are set by a bank you must separately court and satisfy.
  • Pricing carries minimum monthly platform commitments, so a programme with modest card volume pays for capacity it never uses.
  • Programme revenue depends heavily on interchange, which means regulated debit interchange caps and European interchange caps materially change the business case by market.
  • Disputes, chargebacks and fraud losses sit with the programme, and teams that assumed the processor absorbed them discover a real operations headcount requirement.
  • Just-in-time funding makes your own authorisation endpoint a hard availability dependency; if it is slow or down, cards decline at the point of sale.

Answered from the vendors’ own pages

Galileo: What does Galileo cost?

Galileo offers a free plan, a Pro plan at $100/month billed yearly (with a 33% annual discount), and a custom-priced Enterprise plan for unlimited trace capacity.

Source
Marqeta: Do I need a sponsor bank?

Yes. Marqeta is an issuer processor, not a bank. Card programmes run on a sponsor bank BIN, and that bank approves and supervises your programme.

Galileo: Is there a free plan, and what are its limits?

The Free plan includes 5,000 traces per month with unlimited users and unlimited custom evaluations, aimed at developers and small teams experimenting with GenAI.

Source
Marqeta: How does the pricing really work?

A minimum monthly platform fee plus per-transaction and per-active-card charges, offset by a negotiated share of interchange. The interchange split is the substance of the deal.

Galileo: How is usage metered?

Galileo's pricing scales based on the number of traces processed each month, with Free capped at 5,000, Pro at 50,000, and Enterprise offering unlimited trace capacity.

Source
Marqeta: What is just-in-time funding?

Marqeta calls your endpoint at authorisation so you decide and fund each transaction, rather than pre-loading balances onto cards.
