The short version

  • Each has a real cost: Inngest hobby plans pause execution once free quota exhausted; upgrade required to continue; 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.

Where each one falls short

Documented limitations, not opinions. Every one is a constraint you would hit in normal use.

Inngest

  • Hobby plans pause execution once free quota exhausted; upgrade required to continue
  • Pro plan overages carry tiered metering: additional concurrent steps at $25 per 25, span data at $3/GB, scores at $1.50 per 1K, events at $0.50 per 1M

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.
