Comparison

Untimely vs Inngest

Inngest is a durable-execution platform: functions in your codebase, triggered by events or cron, with steps, retries, and flow control. Untimely sits a level up — it is the scheduler people and agents manage as a product, with flexible random windows and direct email or webhook delivery. The two compose: an Untimely webhook can send the event that starts an Inngest function.

Answer first

Choose by the work you are scheduling.

Best when

  • The scheduled unit is a single delivery — an email prompt or one HTTPS call — and adopting a workflow engine for it would be overkill.
  • Non-developers or agents need to create and adjust schedules without touching application code or deploys.
  • Trigger times should vary inside a window; Inngest cron triggers fire at exact times.

Tradeoff

  • Inngest is the better pick when the scheduled work is a multi-step function needing durability: steps, retries, sleeps, concurrency control, and replay.
  • Untimely is the better pick when the schedule itself is the product: visible, editable, humane in its timing, and not coupled to your deploy pipeline.

Side by side

The practical comparison.

Scheduling model

Untimely
Flexible random windows plus fixed-time schedules managed as product data.
Inngest
Cron-triggered and event-triggered functions defined in code and shipped with your app.

Delivery actions

Untimely
Untimely supports Email and Webhook actions for recurring events, so it can send human-facing prompts or call your own HTTPS endpoint on schedule.
Inngest
Runs your function code, which can do anything your app can, with durable steps and retries.

Operations

Untimely
Event UI, run history, API keys. Free tier of 3 events; unlimited on Pro.
Inngest
Execution-based pricing (as of July 2026: a free tier around 50K executions per month, paid plans above that) with tracing and observability for function runs.

Best when

Untimely
You schedule prompts and triggers people care about.
Inngest
You orchestrate reliable background work developers care about.

FAQ

Questions about Inngest

Do Untimely and Inngest compete?

Mostly no. Inngest executes durable workflows in your codebase; Untimely schedules and delivers events as a product. They overlap only where a cron-triggered function does nothing but call an endpoint or send a message — Untimely does that without the workflow engine.

Can Untimely trigger an Inngest workflow?

Yes. Point a webhook action at an endpoint that emits your Inngest event. That gives an Inngest workflow a random-window schedule, which Inngest's cron triggers do not offer natively.

What does Untimely not do that Inngest does?

Durable multi-step execution: steps, retries with backoff, sleeps, fan-out, concurrency keys, replay. Untimely delivers one action per trigger and records the run.
