Inngest
Durable execution platform where the billable unit is a function or step execution rather than a queued message.
- queue
- Yes
- $99/month for Pro, described as a starting price with usage above the included allowance billed on top.
- Not documented
Who it suits.
Multi-step workflows that need durable execution and retries between steps, rather than a bare queue you write a consumer for.
Consider something else if…
Every step is a billable execution, so a three-step workflow costs three times what the run count implies, and the free plan allows five concurrent steps.

Pricing model
Per execution, where a step counts the same as a run, plus separate meters for events ingested, span data, scores and realtime connections. The pricing page ships a calculator because the execution count is not the run count.

“TOTAL EXECUTIONS PER MONTH (30,000 runs × 2 steps per run) + 30,000 runs = 90,000 executions [...] 500 MB span data ingested [...] 10K scores [...] 500k events ingested [...] 50 realtime connections”

Queues
Included per month
50,000 executions a month on the free Hobby plan and 1,000,000 on Pro, pay-as-you-go to 20M. An execution is one function run or one step, so a run with two steps counts as three.
