  • Handling unpredictable LLM behavior with fine-grained error control

The honest half

Where it falls short

Concrete and checkable, so you can decide whether any of them matter to you. This is the half of a review a vendor will not write about 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

Softwr does not host reviews and shows no star rating for Inngest, because a rating we did not collect is not ours to publish. What is here is the pricing and platform detail from the vendor’s own pages, limitations we could state concretely, and alternatives a reviewer confirmed people weigh against it.
