How does uptime monitoring work?
Add a monitor with the URL you want to watch, and it's checked automatically at regular intervals, around the clock. Each check confirms the site responds, returns a healthy status code, and actually serves a valid HTML page – so a site that's technically "up" but serving a blank or garbled page is flagged too. Anything unexpected is logged straight away and reflected in your dashboard. For URLs that aren't meant to be HTML, like a JSON API, you can turn the content check off from that monitor's actions menu.
Will I be notified if my site goes down?
Yes – you'll get an instant email notification the moment a monitored site goes down, and another when it comes back up, so you're rarely the last to know about an outage. From a monitor's settings you can also add a webhook to get the same alerts in Slack, Discord, or your own tooling, alongside or instead of email.
Can I see historical uptime data?
Yes. Every monitor keeps a history of checks over time, so you can see patterns like recurring outages, slow periods, or how reliable a site has been over the last day, week or month. Expanding a monitor also shows a response-time chart for the last 24 hours, so you can spot a site that's getting slower before it goes down entirely.
How many sites can I monitor?
Add as many monitors as you need from your dashboard – each one runs independently, so you can track a whole portfolio of sites or services from a single place.
Can I share a status page with others?
Yes. From the settings menu, choose "Status page" to publish a public page showing the live status of whichever monitors you pick – handy for customers, teammates or a status.yoursite.com-style page, without giving anyone access to your dashboard.
What can I use uptime monitoring for?
- Getting an early warning when a site or server goes offline
- Tracking reliability over time for an SLA or report
- Monitoring staging environments alongside production
- Keeping an eye on third-party APIs your site depends on
What's the difference between this and a redirect or header checker?
This tool watches a site continuously and alerts you to changes over time, whereas the redirect checker and header checker give you a one-off, detailed look at a single request – useful for diagnosing exactly what's happening once you already know something's wrong.
