Deep Dive

A job that stays silent alerts

A closer look at what you get, from the first check to the alert that reaches you.

Simple ping URL

Your job calls one URL when it completes — no SDK required.

Cron-aware scheduling

Uptime parses your cron expression and knows exactly when to expect a ping.

Grace periods

Allow jobs a little slack before marking them late.

Healthy → late → missed

A clear state machine so you always know a job's current status.
Get started

From a ping URL to a missed run

Three steps from an empty dashboard to checks that run on their own.

  1. Create a cron job monitor

    Enter the schedule as a standard cron expression.

  2. Call the ping URL

    Add one line to your job that pings the URL on completion.

  3. Get alerted if it's late

    Uptime tracks expected run times and alerts on missed pings.

FAQ

Frequently asked questions

The questions people ask most before they start monitoring.

Do I need an API key to ping in?

No — the cron-job ping endpoint is public and rate-limited, so a single line in your job is enough.

What happens if my job runs a bit late?

A grace period absorbs normal variance before the job is marked late, then missed.
