Where each one falls short

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

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.

Portkey

  • The free Developer tier records only 10,000 logs per month with 3 day log retention; the $49 per month Production tier raises that to 100,000 logs with $9 per additional 100,000 requests, as of August 2026.

Answered from the vendors’ own pages

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.

Portkey: What happens if I exceed my Portkey plan's request limit?

Production tier ($49/month) charges $9 per additional 100,000 requests beyond the included 100,000. Enterprise customers have custom limits determined through their service agreement. Source: https://portkey.ai/pricing

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.

Portkey: Can I self-host Portkey to avoid per-request billing?

Yes. Portkey offers an Open Source self-hosted version with unlimited requests at no cost, including universal API, routing, guardrails, and load balancing features. Source: https://portkey.ai/pricing

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.

Portkey: How long does Portkey retain my logs and metrics?

Free Developer tier retains logs 3 days and metrics 30 days. Production tier retains logs 30 days and metrics 90 days. Enterprise tier offers custom retention periods. Source: https://portkey.ai/pricing

Source
Portkey: What compliance features are included in the Enterprise plan?

Enterprise tier includes SOC2 Type 2 certification, GDPR compliance, HIPAA compliance, VPC hosting, SSO, advanced guardrails, and dedicated support. Custom pricing required. Source: https://portkey.ai/pricing
