Durable step execution
Wrap existing logic in step.run() so each step gets retries, state, and failure recovery without refactoring the surrounding app.

Durable execution for background jobs, workflows, and AI agents
What is Inngest?
Inngest is a durable execution platform for background jobs, workflows, and AI agents. It moves orchestration concerns such as retries, concurrency, waiting, and observability into the application code while the service handles the execution layer.
The product is designed for teams that want to add reliable step-based logic to existing apps without introducing workers, queues, or a separate orchestration architecture. The source highlights use cases such as long-running workflows, APIs that must survive timeouts, schedules, serverless functions, and event-driven fan-out.
What can Inngest do?
Workflow orchestration
Handle waiting, retries, fan-out, throttling, and scheduling in the platform while the code keeps the orchestration logic close to the function.
Concurrency control
Limit the number of steps that run at once, including per-key and cross-function scopes, to protect downstream services and keep tenant workloads fair.
Step-level observability
Trace runs with logs, metrics, and replayable history so failures can be inspected at step level and revisited later.
Realtime updates
Stream updates from functions in real time, which supports interactive workflows and long-running operations that need progress feedback.
Managed execution
Run background jobs, workflows, and AI agents without adding workers or queues on your side; the platform manages execution infrastructure.
Use Cases
“Durable background jobs”
Use Inngest to run multistep backend jobs that should resume after failures instead of restarting from scratch.
“AI agents and long-running assistants”
Build AI agent flows that can pause for input, wait for events, and continue from the same execution state.
“Shared-resource flow control”
Protect downstream services by capping concurrent steps globally, per tenant, or across multiple functions.
“Event-driven orchestration”
Run workflows that fan out many event-driven tasks and keep each execution traceable and replayable.
“Serverless and scheduled automation”
Support long-running serverless endpoints or scheduled work that needs reliable retries and visibility.
Frequently Asked Questions
How does Inngest fit into an existing codebase?
Inngest runs durable functions by wrapping existing code in steps, so you can add retries, waiting, and orchestration without rebuilding your app around queues or workers.
What pricing options does Inngest offer?
The pricing page shows a free Hobby plan, a Pro plan that starts at $75 per month, and an Enterprise option with contact-sales pricing.
Can Inngest be self-hosted?
Yes. The pricing page says Inngest is open-source and can be self-hosted, while the cloud product adds managed infrastructure and observability.
What kinds of workloads is Inngest built for?
The source highlights durable workflows, background jobs, AI agents, long-running API endpoints, schedules, serverless functions, and event fan-out as common uses.
Does Inngest support flow control for shared resources?
Concurrency control can be applied with global limits, per-key limits, and shared scopes across functions, which is useful when you need to protect downstream systems or manage multi-tenant load.
