Moonlight Monitor
Website and cron job monitoring

Know the moment
your site goes down,
not when customers tell you.

Everything you need to know your site is up

Moonlight Monitor does a few things and does them well: checks your sites, watches your scheduled jobs, and tells you fast when something breaks.

On every plan

Website uptime checks

Monitor any public URL and get alerted when it becomes unavailable.

Email alerts

Get an email the moment a monitor goes down, and another when it recovers.

Heartbeat monitoring

Have a cron job or server ping us on a schedule. If a ping goes missing, you hear about it.

Response time and incident history

See how fast your site responds and review past incidents, with a weekly summary in your inbox.
