The short version

  • Only Kong Gateway has a free tier, so it costs nothing to try first.
  • Each has a real cost: Astra push-to-card costs materially more per transaction than ACH, so a platform that switches all payouts to instant sees payment costs rise sharply, and the usual answer of charging the recipient for speed only works where recipients will pay.; Kong Gateway the free open-source gateway lacks the analytics, portals, and support of the paid Konnect tiers.
  • They diverge on capability: Astra covers Instant disbursements, Kong Gateway covers API request routing.
  • Prices and features above were last checked on 31 August 2026.

Where each one falls short

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

Astra

  • Push-to-card costs materially more per transaction than ACH, so a platform that switches all payouts to instant sees payment costs rise sharply, and the usual answer of charging the recipient for speed only works where recipients will pay.
  • Original Credit Transaction support is not universal across card issuers, so a proportion of payouts fall back to slower rails and you must build and explain a two speed experience rather than promising instant to everyone.
  • The programme depends on Cross River Bank as sponsor, a bank with concentrated fintech exposure and a documented regulatory history, so a single supervisory action on that institution is a direct operational risk to your payouts.
  • Nothing is published on pricing, and per transaction economics vary by rail and volume, so small platforms cannot estimate cost before a sales conversation and have limited leverage in it.
  • FedNow reach still depends on the recipient bank participating, so instant account-to-account is not available to every recipient and the routing logic has to degrade gracefully, which is more integration work than the single API framing suggests.

Kong Gateway

  • The free open-source gateway lacks the analytics, portals, and support of the paid Konnect tiers.
  • Plus tier caps API requests at 1M/month before incurring per-million overage charges.
  • Enterprise pricing is custom and not published, making budgeting harder without sales contact.
  • Configuration and plugin management can require significant operational expertise to run at scale.

Answered from the vendors’ own pages

Astra: Who is the sponsor bank?

Cross River Bank. All banking and payment services run through that relationship, so the bank should be part of your diligence rather than an implementation detail.

Kong Gateway: Is Kong Gateway free?

Kong's core gateway is open source and free to self-host. Kong Konnect, the managed cloud platform, offers a 30-day free trial before moving to paid Plus or custom Enterprise pricing.

Source
Astra: Do I have to prefund payouts?

Not necessarily. Astra offers a net debit arrangement where disbursements settle against a reserve rather than a permanently funded float account, which is the main working capital argument for the product.

Kong Gateway: How is usage metered on the Plus plan?

The Plus plan includes 1M API requests per month, with additional usage billed at $200 per extra 1 million requests up to a 10M/month cap, plus per-gateway and per-LLM-model charges.

Source
Astra: Is every payout instant?

No. Push-to-card requires the recipient card issuer to support Original Credit Transactions, and FedNow requires the recipient bank to participate. The rest fall back to ACH.

Kong Gateway: What support is included?

Plus includes email support with a 2-business-day SLA, while Enterprise adds dedicated success managers and professional services.

Source
Astra: What does it cost?

Nothing is published. Pricing is per transaction and varies by rail and volume, and card rails cost considerably more than ACH.
