Untimely

Comparison

Untimely vs Inngest

Inngest supports scheduled functions with 1-second to 5-minute jitter after each cron boundary. Untimely offers broader random windows and direct Email, Webhook, or Pro Slack delivery without maintaining scheduler infrastructure. Keep Inngest for the workflow code that runs after the trigger.

Which fits your workflow?

Choose for the job you need done.

Best when

  • Send a recurring prompt directly when the complete job is delivering a message.
  • Let the person using the reminder adjust it without changing application code.
  • Add a random-window trigger to an existing workflow through an endpoint that emits your Inngest event.

Tradeoff

  • Inngest is the better pick when the scheduled work is a multi-step function needing durability: steps, retries, sleeps, concurrency control, and replay.
  • Use Inngest jitter when a small random offset solves the problem. Choose Untimely for wider windows and recurring delivery configured in the app or API.

Inngest
You need durable execution for background workflows.

FAQ

Questions about Inngest

Can I keep Inngest for the workflow?

Yes. An Untimely Webhook action can call an endpoint that emits your Inngest event. Untimely chooses when to trigger it; Inngest handles the workflow steps. Keep retries, concurrency controls, and replay requirements in the system responsible for executing that work.

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. Inngest already offers 1-second to 5-minute cron jitter; Untimely is useful when you want a wider window, such as three triggers over seven days during working hours.

What does Untimely not do that Inngest does?

Durable multi-step execution: steps, retries with backoff, sleeps, fan-out, concurrency keys, replay. Untimely records delivery runs and supports a two-step AI generation and delivery pipeline on Pro.
