The short version

  • Each has a real cost: Hasura active model definition: model/command accessed more than 1,000 times monthly; 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: Hasura covers GraphQL API, Svix covers Automatic retries.
  • 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.

Hasura

  • Active model definition: model/command accessed more than 1,000 times monthly
  • Private DDN requires Base or Advanced plan

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.
