The short version

  • Only Svix has a free tier, so it costs nothing to try first.
  • Each has a real cost: 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.; TrueLayer variable recurring payments, the strongest reason to choose TrueLayer, is a UK construct, and European businesses expecting the same capability in their market will not get it on the same timetable.
  • They diverge on capability: Svix covers Automatic retries, TrueLayer covers Pay by bank.
  • 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.

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.

TrueLayer

  • Variable recurring payments, the strongest reason to choose TrueLayer, is a UK construct, and European businesses expecting the same capability in their market will not get it on the same timetable.
  • Payment conversion varies substantially by bank, and a bank with a slow or broken authentication journey drags results down regardless of vendor, so aggregate coverage numbers say little about your actual mix.
  • Pay by bank has no chargeback mechanism, which merchants like until a customer disputes a purchase and finds no scheme protection, making it a poor fit for categories where buyers expect card style recourse.
  • Pricing is unpublished and varies by market and product, so multi-country merchants cannot model cost without a full sales engagement and often find rates differ significantly between countries.
  • Open banking authentication requires the customer to leave the checkout and authorise in their banking app, and that redirect remains the largest source of drop-off compared with a stored card.

Answered from the vendors’ own pages

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.

TrueLayer: Is VRP available outside the UK?

No. Variable recurring payments are a UK capability. EU adoption is on a slower path, with UK commercial VRP expanding into ecommerce during 2026.

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.

TrueLayer: What does TrueLayer cost?

Not published. Per-payment fees are quoted by volume, market and product, usually with a platform component and a minimum commitment.

Svix: What counts as a message?

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

TrueLayer: Are there chargebacks on pay by bank?

No. Bank transfers have no card scheme chargeback mechanism, which removes that cost but also removes buyer recourse, so it suits some categories and not others.

Svix: Does it handle inbound webhooks?

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

TrueLayer: Which countries are covered?

The UK plus a substantial set of European markets under PSD2, though bank-level coverage and conversion vary by country and should be checked for your specific mix.
