Inngest

Inngest is an open-source durable execution platform for running background jobs, scheduled tasks and AI workflows reliably, with a free cloud tier.

Our take: Inngest removes most of the plumbing behind reliable background work: queues, retries, schedules and concurrency control become a few lines of code.

Inngest is a durable execution platform that lets developers run background jobs, scheduled tasks and multi-step AI workflows with automatic retries, written in TypeScript, Python or Go. The cloud service is free up to 50,000 executions a month, Pro starts at $99 a month, and the open-source core can be self-hosted.

The bottom line

A strong default for code-first background workflows, especially on serverless.

One line each. Open a row for detail.

What it really isA durable execution and event platform that turns app functions into retryable, multi-step workflows.
Our takeInngest removes most of the plumbing behind reliable background work: queues, retries, schedules and concurrency control become a few lines of code.
The free tier is large enough for side projects and early products, and the open-source server is a real exit option. Watch the metered parts as you grow: executions, concurrent steps, seats and events all have caps on each plan.
Why we rate itGenerous free tier, open-source core and reliable workflows without running queues.
The catchUsage-based extras add up at scale, and enterprise security features need a custom contract.

  • AI agent and LLM workflows
  • Teams replacing hand-built queues

  • Teams standardized on AWS-native state machines
Trade-offs

Friction report

Trade-offs to know before signing up.

  1. Time to value
    Short for developers: install an SDK, add an endpoint and run the local dev server.
  2. Scale breakpoint
    Free tier stops at 50,000 executions and 5 concurrent steps a month.
  3. Walled garden
    Low: open-source server can be self-hosted; workflows stay in your code.
Still a fit?
If none of these block you, start on the free plan.

Frequently Asked Questions

How much does Inngest cost?

Inngest has a free tier, Pro from $99 a month with 1 million executions, Business from $499 a month with 10 million executions, and quote-based Enterprise. Extra concurrency, seats and events are billed on top (checked 4 October 2026).

Is Inngest free?

Yes, up to a point. The free tier includes 50,000 executions, 500,000 events, 5 concurrent steps and 5 seats a month, with no credit card. The open-source version can also be self-hosted (checked 4 October 2026).

What is the difference between Inngest and Temporal?

Both provide durable execution. With Temporal you run worker processes that poll for tasks; with Inngest you expose your functions over an HTTP endpoint, which also works on serverless platforms. Inngest also includes event ingestion, flow control and tracing in its cloud plans.

What are some alternatives to Inngest?

Common alternatives are Temporal, trigger.dev, AWS Step Functions and Prefect. Temporal and Step Functions suit large orchestration needs; trigger.dev is closest in its code-first approach; Prefect leans toward data pipelines.

Which languages does Inngest support?

Inngest's docs list SDKs for TypeScript, Python and Go, plus a REST API.

Can I self-host Inngest?

Yes. Inngest says it is open source and can be self-hosted; the code is on GitHub at inngest/inngest.
