Launched in 2021, Inngest is a serverless, event-driven workflow engine for background jobs, scheduled tasks, and multi-step AI pipelines that needs no queue or worker infrastructure to manage. Each function step retries independently instead of restarting the whole run, and functions deploy natively alongside Vercel, Cloudflare Workers, or any Node.js backend.
About Inngest
Inngest is an event-driven durable workflow platform founded in 2021 by Tony Holdstock-Brown and Dan Farrelly. The company has raised $34M across four rounds including a $3M seed in July 2023 from GGV Capital and a $6.1M Series A in January 2024 from Andreessen Horowitz, with a Series B in May 2025. Based in San Francisco with a 9-person team, Inngest lets developers build reliable background jobs, scheduled workflows, and AI agent tasks on serverless platforms without managing infrastructure. The platform is serverless-first: TypeScript, Python, and Go SDKs deploy alongside your existing app on Vercel, Cloudflare Workers, Hono, or any Node.js backend, with the orchestration engine and dashboard hosted by Inngest rather than self-managed. Inngest added MCP (Model Context Protocol) support to its local dev server in 2026, letting Claude Code, Cursor, and other AI assistants connect directly to functions for debugging. Inngest competes with Trigger.dev, which runs compute but lacks the event-driven model, Temporal, which is enterprise-grade but carries heavier infrastructure overhead, and traditional queue systems like BullMQ. Reviewers point to the combination of event-driven architecture, zero infrastructure on Vercel, and a free Hobby tier as the main reason early-stage teams pick it over those alternatives.
Pricing
Hobby: free, with additional executions beyond the included monthly allowance billed at $50 per million. Pro: monthly subscription with higher concurrency and user caps for growing teams. Enterprise: custom pricing with SAML, RBAC, audit trails, and dedicated support. All plans include unlimited dev and staging environments.
Key Features
- Event-Driven Workflows: Everything is triggered by events, eliminating the need to manage traditional queues or worker processes. Functions respond to events from webhooks, external services, or scheduled triggers.
- Step-Level Durability: Each step is backed by its own queue job with automatic retry on failure, saving costs and complexity compared to queue-level durability approaches used by other platforms.
- Multi-Tenant Flow Control: Built-in concurrency, throttling, rate limiting, prioritization, and debouncing controls handle multi-tenant fairness and reliability without custom implementation.
- Scheduled and Cron Jobs: Schedule jobs to run minutes or weeks into the future, enabling time-delayed workflows, deferred notifications, and reminder systems without additional infrastructure.
- Native Vercel Integration: Automatically syncs deployed code, sets environment variables, and manages infrastructure synchronization when you deploy Next.js apps, eliminating manual setup and worker processes.
- Event History and Replay: Stores full event history for observability, testing, and replay. Re-run failed workflows in bulk or test with historical events without re-triggering real upstream sources.
Pros
- The free Hobby tier is enough for most side projects and early-stage startups to run real background jobs without paying anything upfront.
- Automatic step-level retries mean a single flaky step gets retried in isolation rather than re-running an entire multi-step workflow, which reviewers say saves real debugging time.
- MCP support lets you debug and trigger functions directly from Claude Code or Cursor, a convenience most workflow platforms don't offer yet.
Cons
- Inngest is fully proprietary with no self-hosting option, unlike Temporal or Trigger.dev, so teams with strict data-residency or air-gapped requirements can't run it themselves.
- Every piece of workflow logic has to be wrapped in explicit step.* calls with cache keys for resumability, which is more verbose than Trigger.dev's plain async function style.
- Documentation thins out fast for advanced cases like multi-region setups and integration troubleshooting, so non-standard architectures take more trial and error to get working.

Frequently Asked Questions
What does Inngest actually cost?
Inngest has three tiers. Hobby is free, Pro costs $75 per month with higher concurrency and user limits, and Enterprise uses custom pricing that adds SOC 2 compliance, SAML, RBAC, and audit trails. Beyond the included Hobby allowance, extra executions bill at $50 per million. All tiers include unlimited dev and staging environments.
Can you use Inngest without paying?
Yes, the Hobby plan stays free for good rather than expiring after a set period. It includes 100,000 function executions per month, 5 concurrent steps, and access for up to 3 team members, enough for most development work and small production apps. Functions pause once the monthly quota is used until the next billing cycle or an upgrade to Pro.
What should you use instead of Inngest?
The closest alternatives are Trigger.dev, which runs your own compute but lacks Inngest's fully event-driven trigger model, and Temporal, which offers deeper workflow control across more languages but requires running or subscribing to a dedicated cluster. Teams wanting a lighter-weight, queue-free option on Vercel or Next.js typically pick Inngest over either.
Inngest or Temporal: which should you pick?
Temporal is the more capable option for complex, long-running, mission-critical workflows across many languages, with deterministic replay, but it typically needs a dedicated cluster or a Temporal Cloud subscription to run. Inngest needs no cluster: functions deploy directly alongside your existing Vercel, Cloudflare, or Node.js app. Teams with deep multi-language enterprise workflows should lean toward Temporal; teams shipping typical web app background jobs in TypeScript or Python usually start with Inngest instead.
What does it take to start using Inngest?
Getting started means creating a free Inngest account, installing the TypeScript, Python, or Go SDK, and writing your first function with an event trigger and one or more step calls. The built-in dev server runs locally so you can test event flows and step retries before deploying to Vercel, Cloudflare, or any Node.js host. Beginners typically have a working scheduled or event-triggered job running within an hour by following the Next.js quick start guide.
Top Alternatives
- Trigger.dev: Trigger.dev opens source with plans from $10/month; Inngest answers with zero-infrastructure Vercel integration and a free Hobby tier.
- Temporal: Temporal handles workflows-as-code with deterministic replay for resilient microservices at large scale; Inngest handles zero-infrastructure background jobs on Vercel or Node.js without a cluster to manage.
- n8n: n8n brings a free workflow automation platform built for technical teams; Inngest brings a code-first, event-driven engine built for developers shipping on Vercel or Next.js.
