Limits
| Tier | Metric | Value | Notes |
|---|---|---|---|
| — | billing unit | Step = one durable function step. Function runs are composed of steps. | Billing unit |
| — | deploy pattern | Single HTTP handler (/api/inngest) that Inngest invokes via HTTPS | Serve pattern |
| — | hosting model | You host the code (Vercel/Lambda/Fly), Inngest hosts orchestration | Hybrid |
| — | languages | TypeScript (primary), Python, Go | SDK languages |
| — | primitives | step.run, step.sleep, step.waitForEvent, step.invoke, cron, events | Core primitives |
| — | retries | Automatic retries with backoff. Deadline-aware. Replayable. | Retries |
| — | vs temporal | Lighter DX than Temporal (no worker fleet), trade-off: less control over execution | Temporal comparison |
| — | vs trigger dev | Older + more production-battle-tested than Trigger.dev, similar ergonomics | Trigger comparison |
