Untimely

Comparison

Untimely vs FastCron

Want random timing without writing a cron expression? Choose a window and frequency in Untimely, then send an email or call your endpoint when the event runs. FastCron also supports random timing; choose Untimely for its window-based setup and direct reminder delivery.

Which fits your workflow?

Choose for the job you need done.

Best when

  • Set the acceptable time window in an app rather than work out which cron fields to randomize.
  • Deliver a recurring email reminder without maintaining an endpoint to send it.
  • Let an agent create and inspect events through the API or MCP server.

Tradeoff

  • FastCron supports random minute and hour fields, bounded hours, multiple random daily runs, and random delays. Keep it if those controls and HTTP delivery fit your job.
  • Choose Untimely for event-based setup, direct email or Slack delivery (Slack requires Pro), and no scheduler infrastructure to maintain. Your endpoint still runs webhook jobs.

FAQ

Questions about FastCron

Why switch if FastCron already randomizes times?

You may not need to. Keep FastCron if its random cron fields and HTTP delivery cover the job. Try Untimely when you want to configure windows and frequency directly, or send email reminders from the same scheduler.

Doesn't FastCron already do random times?

Yes. FastCron supports bounded random hours, multiple random daily runs, and random delays. Untimely offers an event interface for windows and frequency, with Email, Webhook, and Pro Slack delivery.

Is Untimely a FastCron alternative?

For random-window scheduling and email delivery, yes. FastCron remains a strong pick when you want familiar cron syntax, team seats, sub-minute intervals, and failure alerting on classic jobs.

How does pricing compare?

As of September 30, 2026, FastCron lists 15 free jobs, Starter at $6/month, and Pro at $20/month. Untimely has a free tier limited to 3 events and a Pro plan with unlimited events at $6/month. Check both pricing pages before deciding.
