The short version

  • Only Hookdeck has a free tier, so it costs nothing to try first.
  • Each has a real cost: Finxact fiserv sells several core platforms, so a buyer should demand written investment and support commitments for Finxact specifically rather than trusting that the surviving brand implies a protected roadmap.; Hookdeck pricing meters delivered events, so fan-out multiplies the bill: one inbound event routed to four services counts as four deliveries.
  • They diverge on capability: Finxact covers Cloud native core, Hookdeck covers Ingest and persist.
  • 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.

Finxact

  • Fiserv sells several core platforms, so a buyer should demand written investment and support commitments for Finxact specifically rather than trusting that the surviving brand implies a protected roadmap.
  • Core migration is a multi year programme where the licence is a small share of total cost against integration, data migration and parallel running.
  • Buying the core from Fiserv strengthens a relationship that already covers cards and payments, which weakens your negotiating position across the whole estate at renewal.
  • It is a United States product with United States regulatory and product assumptions, so international banks get little from it.
  • Being part of a very large vendor changes the service experience: the responsiveness that made Finxact attractive as a startup is not guaranteed inside a company of Fiserv's scale.

Hookdeck

  • Pricing meters delivered events, so fan-out multiplies the bill: one inbound event routed to four services counts as four deliveries.
  • Free-tier retention is three days, which is shorter than the time it typically takes to notice a failing integration, so the payloads needed for a replay are often already gone.
  • It becomes a single point of failure in front of every third-party integration, and an outage there means every provider webhook queues or fails at once.
  • The transformation layer runs JavaScript in a constrained environment, so anything that needs a database lookup or an external call has to happen downstream instead.
  • For a team already running Kafka or SQS the value is mostly the console and the replay UI, which is a hard cost to justify against infrastructure they already operate.

Answered from the vendors’ own pages

Finxact: Is Finxact still sold under its own name?

Yes. Fiserv acquired it in 2022 and continues to market it as Finxact from Fiserv, winning named core deals with it.

Hookdeck: Is there a free plan?

Yes, ten thousand events a month with three-day retention and one user.

Finxact: Is it genuinely cloud native?

Yes, API first with real time posting on public cloud, rather than a hosted version of a legacy core.

Hookdeck: How is usage counted?

By delivered events, so a single inbound webhook fanned out to three destinations counts as three.

Finxact: How long is a migration?

Plan in years. Even a focused deployment is a multi year programme once integration and data migration are counted.

Hookdeck: Can I replay a failed webhook?

Yes, individually or in bulk from the console, with the original payload.

Hookdeck: Does it work for outbound webhooks too?

Yes, the same queueing, retry and observability applies to webhooks you send.
