🚨 Down and up alerts
An email when a check fails twice in a row, another when it recovers, with the reason and how long it was out.
📊 Status page
A public page at /s/your-name/ with live status, 90 days of uptime bars and recent incidents. Free.
🔒 SSL warnings
A heads-up 14, 7 and 1 day before a certificate expires. UptimeRobot only includes this on paid plans.
💸 $5, not $13
Pro gives 50 monitors at 1-minute checks for $5/month. UptimeRobot Solo is $13/month for 10 (checked October 2026).
Questions
Is it really free?
Yes. 10 monitors checked every 5 minutes, email alerts, SSL expiry warnings and a public status page, with no card and no time limit. Pro is $5/month for 50 monitors checked every minute.
What counts as down?
A connection error, a timeout (10 seconds), an HTTP status of 400 or higher, or, for keyword monitors, the keyword missing (or present, if you choose). A failed check is retried a few seconds later before anything is reported, so a single blip doesn't page you.
Where do alerts go?
By email to your account address the moment a monitor goes down, and again when it comes back up with how long it was down. Pro adds up to 10 alert contacts.
Can I monitor servers on my home network?
No. For safety, private and local addresses (10.x, 192.168.x, localhost and similar) can't be monitored; the checker only reaches public websites.
