Free Website Uptime Monitoring

We'll monitor up to 20 of your sites for FREE! And we'll notify you by email if a site is down.

If you sign up for low cost text message alerts, we'll even send text messages to your phone(s).

What Are SMS Units?

With our paid plans, you can receive text messages (SMS) on your phone alerting you when a site's status changes.
We only send messages the first time we see your site is down. The next time we send a message is when the site is back up.

Each plan includes a number of "SMS Units". Our $30 annual plan includes 500 SMS units.
Each message sent to a phone number consumes a number of SMS Units.

Destination SMS Units Per Text Message
US, Canada 1
International 3 - 7
(see SMS Units By Country)


For example, if you're in the US and have one US phone number registered for alerts, when one of your sites goes down, you receive one text message, which consumes 1 SMS Unit. If you have 3 registered US phone numbers, 3 text messages are sent, consuming 3 SMS Units.

If you're in Switzerland and have one Swiss phone number registered for alerts, when one of your sites goes down, you receive one text message, which consumes 5 SMS Unit. If you have 3 registered Swiss phone numbers, 3 text messages are sent, consuming 15 SMS Units.

Text messages sent when your site comes back up consume the equivalent number of SMS Units.

Other messages sent by us, like opt-in messages, do not consume SMS Units.
 

Message and data rates imposed by your phone plan apply.
