Free website monitor

Free Website Monitor. Pinged Every Minute, Forever.

A website that nobody is watching can be down for six hours before anyone notices. SiteGuardian pings your URL once a minute, every minute, and emails you the second it stops responding. Type the URL and your email below — we'll start watching right away. Free forever, no card, no account to start.

Loading…Free forever · No card required

We'll alert you the moment this URL stops responding. Free forever, one URL, no account needed to start.

What you'll see

  • A once-a-minute ping to your URL.
  • An email the moment your URL stops responding.
  • A second email the moment it comes back up.
  • Free forever: one URL, one email.
  • Open the dashboard to add a second URL or step up the cadence.

Stop being the on-call engineer.

Skip the manual checks — SiteGuardian watches your URL around the clock and emails you the second it goes off.
