The short version

  • Each has a real cost: Inngest hobby plans pause execution once free quota exhausted; upgrade required to continue; RudderStack on the free plan data processing stops after a second consecutive overage rather than being billed, so exceeding 250,000 events twice breaks the pipeline
  • Prices and features above were last checked on 30 August 2026.

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

RudderStack

  • On the free plan data processing stops after a second consecutive overage rather than being billed, so exceeding 250,000 events twice breaks the pipeline
  • The free plan allows 250,000 events a month
  • Growth starts at $265 a month for 1 million events, with volume sold in tiers up to 25 million
  • Overage is charged as the gap to the next tier's price rather than per event, so a small excess costs a full tier step
