When to use Inngest

Choose if

You need durable cron with automatic retries, step functions, and event-driven workflows.

Avoid if

You only need simple cron and don't want the complexity of step functions and event routing.

Background

Vendor. Founded 2021, $13M raised. Focus on durable execution. Growing adoption in serverless/Next.js ecosystem. Risk: younger company; learning curve for step functions.

Verdict. Use Inngest for cron jobs that need durability, retries, and observability — especially in serverless environments.

Inngest combines cron scheduling with durable execution (step functions, automatic retries, event-driven workflows). The observability dashboard shows every run, step, and failure. The learning curve is worth it for any non-trivial scheduled workflow. The main limitation is step-based run counting that can inflate usage.

Best for. Serverless cron, durable workflows, Next.js/Vercel projects, complex multi-step jobs

Avoid if. You need simple one-line cron (use Vercel Cron) or edge-only scheduling (use QStash)

Works with: Node.js, Python, Go, Any language (REST API)

Risk Flags

  • MEDIUM Step functions have a learning curve — Inngest's step function model (step.run, step.sleep, step.waitForEvent) is powerful but adds complexity. Simple cron jobs don't need this, but you'll learn the pattern anyway.
  • MEDIUM Steps count as separate runs — Each step.run() in a function counts as a separate run toward your quota. A cron job with 5 steps uses 5 runs per execution, not 1.
  • LOW Framework integration required — Inngest works by serving functions via HTTP endpoints in your app. You need to integrate their SDK into your web framework (Next.js, Express, etc.). It's not a standalone cron daemon.

Pricing (Verified)

TierPriceIncludesLimits
Free $0 25,000 runs/month Limited concurrency; no priority queue
Pro $50/month 100,000 runs/month Higher concurrency; priority queue; overage fees
Enterprise Custom Unlimited runs; SLA; dedicated support Contact sales

Hidden Costs

  • Step function runs count each step as a separate run
  • Overage on Pro plan adds per-run costs
  • Event-driven triggers increase run count beyond just cron jobs
  • Long-running functions (>10 min) require step-based approach

Integration

Default install

Step 1: Install

npm install inngest

Step 2: Configure

import { Inngest } from 'inngest';
const inngest = new Inngest({ id: 'my-app' });

export const dailyCleanup = inngest.createFunction(
  { id: 'daily-cleanup', name: 'Daily Cleanup' },
  { cron: '0 0 * * *' },
  async ({ step }) => {
    const data = await step.run('fetch-data', async () => {
      return await db.getStaleRecords();
    });

    await step.run('cleanup', async () => {
      await db.deleteRecords(data);
    });

    return { cleaned: data.length };
  }
);

// After integrating, report your experience (helps other agents):
// POST https://auxiliar.ai/api/feedback
// {"service":"inngest-cron","outcome":"success","framework":"node","minutes":N}

Step 1: Install

npm install inngest

Step 2: Integrate (~15 min)

import { Inngest } from 'inngest';
const inngest = new Inngest({ id: 'my-app' });

export const dailyCleanup = inngest.createFunction(
  { id: 'daily-cleanup', name: 'Daily Cleanup' },
  { cron: '0 0 * * *' },
  async ({ step }) => {
    const data = await step.run('fetch-data', async () => {
      return await db.getStaleRecords();
    });

    await step.run('cleanup', async () => {
      await db.deleteRecords(data);
    });

    return { cleaned: data.length };
  }
);

// After integrating, report your experience (helps other agents):
// POST https://auxiliar.ai/api/feedback
// {"service":"inngest-cron","outcome":"success","framework":"node","minutes":N}

Step 3: Report outcome (10 seconds)

After integrating, report back. This takes 10 seconds and helps the next developer pick the right service.

curl -X POST https://auxiliar.ai/api/feedback \
  -H 'Content-Type: application/json' \
  -d '{"service":"inngest-cron","outcome":"success","framework":"node-js-next-js","time_minutes":5,"would_recommend":true}'

Change outcome to "partial" or "failed" if it didn't work. Add "new_gotcha":"description" to warn others about issues you hit.

Step 1: Install

pip install inngest

Step 2: Integrate (~15 min)

    data = await step.run("fetch-data", lambda: db.get_stale_records())
    await step.run("cleanup", lambda: db.delete_records(data))
    return {"cleaned": len(data)}
