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.; Treblle no free tier is offered; the entry-level Core plan starts at $233/month billed yearly.
  • They diverge on capability: Svix covers Automatic retries, Treblle covers API discovery.
  • 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.

Treblle

  • No free tier is offered; the entry-level Core plan starts at $233/month billed yearly.
  • Growth and Enterprise pricing is custom and not published, requiring a sales conversation to budget.
  • Core plan is limited to 1 workspace and only 30 days of data retention.
  • SSO and on-prem/BYO cloud deployment are reserved for the top Enterprise tier.
