Inngest is a durable execution platform for event-driven workflows and background jobs. Compare its features, usage-based pricing, and alternatives.
Inngest is a durable execution platform, founded in 2021 by CEO Tony Holdstock-Brown and CTO Dan Farrelly and headquartered in San Francisco, that helps developers build reliable event-driven workflows and background jobs. Its core model treats functions as a series of individually durable steps: each step's result is checkpointed, so if a failure occurs mid-execution, the function resumes from the last successful step instead of starting over.
The company has raised roughly $34 million in venture funding, including a 2024 round led by Andreessen Horowitz with participation from Vercel CEO Guillermo Rauch, and a subsequent $21 million Series A. Inngest is designed to run on virtually any platform, including serverless environments like Vercel and AWS Lambda, without developers needing to operate their own message queues or worker infrastructure.
Inngest's step functions automatically retry and checkpoint progress, so multi-step processes like AI agent pipelines, onboarding flows, and data pipelines survive failures without manual intervention. Event-driven triggers let a single event fan out to multiple functions, and built-in scheduling supports both cron-style recurring jobs and one-off delayed execution.
Flow control features including concurrency limits, throttling, and rate limiting protect downstream systems and APIs from being overwhelmed, while a real-time dashboard gives developers visibility into function execution, traces, and failures. SDKs integrate directly into existing application code across popular languages and frameworks, avoiding the need for a separate workflow server.
Inngest's Hobby plan is free with no credit card required, including 50,000 monthly executions, 5 concurrent executions, 500,000 events, 3 team users, and 24-hour trace retention — enough for individual developers and small projects to fully evaluate the platform.
The Pro plan starts at $99 per month with roughly 1 million included executions and metered overage pricing beyond that ($50 per additional 1 million executions, among other overage rates), while Enterprise moves to custom pricing with SAML SSO, RBAC, 90-day trace retention, and dedicated support for teams running critical workflows at scale.
