The short version

  • Only Svix has a free tier, so it costs nothing to try first.
  • Each has a real cost: Neonomics coverage outside the Nordics and the UK is comparatively shallow, so a pan European merchant will find gaps and inconsistent bank behaviour in southern and eastern markets.; Svix the Professional tier at 490 US dollars a month includes the same 50,000 messages as the free tier, so the upgrade buys SLA, throughput and retention rather than volume, which is a jarring step for a growing product.
  • They diverge on capability: Neonomics covers Payment initiation, Svix covers Automatic retries.
  • 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.

Neonomics

  • Coverage outside the Nordics and the UK is comparatively shallow, so a pan European merchant will find gaps and inconsistent bank behaviour in southern and eastern markets.
  • It is a small company relative to Tink and TrueLayer, so supplier viability and the depth of engineering support behind bank API changes are genuine procurement questions.
  • Payment initiation only means the merchant handles settlement, reconciliation and refunds, and there is no chargeback framework to fall back on.
  • Integrating a recently acquired UK business means two regulatory entities and, for a period, two technology stacks, so cross market feature parity is a promise rather than an existing state.
  • Conversion is governed by each bank's own authentication experience, and Nordic BankID flows behave differently from UK app redirects, so a single UX cannot be assumed across the footprint.

Svix

  • The Professional tier at 490 US dollars a month includes the same 50,000 messages as the free tier, so the upgrade buys SLA, throughput and retention rather than volume, which is a jarring step for a growing product.
  • Only attempted messages count toward usage, but a customer with many subscribed endpoints multiplies a single event into many billable messages, and forecasting that fan-out before launch is difficult.
  • The open source server is MIT licensed but trails the hosted product in features, so self-hosting is a fallback position rather than a genuinely equivalent option.
  • Routing outbound customer traffic through a third party puts a vendor in the delivery path for events your customers may treat as contractual, which some security reviews will not accept.
  • Payload retention is 30 days on the free tier and 90 on Professional, so anyone needing longer delivery history for audit must pay for Enterprise or log independently.

Answered from the vendors’ own pages

Neonomics: Is Neonomics authorised in the UK?

Yes, through the acquisition of Ordo, an FCA authorised open banking payments firm, approved by the FCA and the Norwegian regulator.

Svix: How much does Svix cost?

Free up to 50,000 messages a month; Professional starts at 490 US dollars a month with the same included volume but better SLA and throughput.

Neonomics: Does it support variable recurring payments?

Yes in the UK through the Ordo capability, subject to which banks support commercial VRP; support elsewhere is more limited.

Svix: Can I self-host it?

Yes, there is an MIT licensed server, but it lags the hosted service in features and has no SLA.

Neonomics: Does Neonomics hold merchant funds?

No. It initiates payments; settlement, reconciliation and refunds remain with the merchant or its payment provider.

Svix: What counts as a message?

Attempted or transformed deliveries. Retries and messages filtered out because no endpoint subscribed are not charged.

Svix: Does it handle inbound webhooks?

Its focus is outbound sending on behalf of API providers, not receiving webhooks from third parties.
