The short version

  • Only KeystoneJS has a free tier, so it costs nothing to try first.
  • Each has a real cost: KeystoneJS database support is limited to PostgreSQL, MySQL and SQLite; 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: KeystoneJS covers REST API, 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.

KeystoneJS

  • Database support is limited to PostgreSQL, MySQL and SQLite
  • Keystone 5 is a separate legacy product documented on a different site and is not covered by the Keystone 6 docs
  • Upgrading requires following a dedicated Migrate to 8.0.0 guide, so major versions are not drop-in
  • Free support is a community Slack; enterprise-grade consulting and support is a separate paid engagement with Thinkmill and no published price

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.

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.

KeystoneJS: What are hosting costs for KeystoneJS?

KeystoneJS is self-hosted and deployment-agnostic. Hosting costs depend on your chosen deployment platform (Vercel, AWS, Heroku, etc.) and infrastructure, not KeystoneJS itself.

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.

KeystoneJS: Does KeystoneJS offer paid support?

Enterprise support with tailored options is available from Thinkmill, the company behind KeystoneJS. Pricing details available upon request.

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.
