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.; Trustly it is majority-owned by Nordic Capital, a private equity firm, so its long-term roadmap is ultimately oriented toward an eventual sale or IPO rather than indefinite independent operation.
  • They diverge on capability: Svix covers Automatic retries, Trustly covers Pay by bank checkout.
  • 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.

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.

Trustly

  • It is majority-owned by Nordic Capital, a private equity firm, so its long-term roadmap is ultimately oriented toward an eventual sale or IPO rather than indefinite independent operation.
  • Consumer familiarity with paying by bank transfer still lags card payments in most markets, so merchants typically see it used as a secondary option rather than a full card replacement.
  • The 1.15 to 3.15% merchant fee range is not a single published rate, so a merchant cannot know its actual cost without a sales negotiation.
  • As with all open banking-dependent payment methods, reliability depends on the consistency of the underlying banks' own APIs, which Trustly does not control.
  • Its verified payout functionality is heavily used in gaming and gambling, a sector with additional regulatory scrutiny, which is worth factoring in when evaluating vendor risk exposure by association.
