Free Website Uptime Monitor: Uptime Robot: "

Uptime is a pretty important factor for the success of a website which directly effects the number of visitors, visitor loyalty, search engine positions & more.

Here is a lovely free service which is created by me & Daniel Rimille of SSLmatic to minimize downtime.

Uptime Robot is a totally free service which monitors your websites every 5 minutes & alerts you if they go down.

It allows you to monitor up to 50 websites & alerts can be received via e-mail or SMS (Twitter & RSS coming soon).

You can add multiple alert contacts to notify multiple users in case of a downtime.

It is possible to monitor both http & https addresses which is pretty important to check if the SSL certificate installed functions correctly.

The service has a simple & fully Ajaxed interface for a faster usage.

P.S. Uptime Robot will hopefully get mature within a short time. But during that period, if you're looking for a more professional service, you may want to check paid ones like Pingdom, SiteUptime, AreMySitesUp…

Upcoming features

• RSS & Twitter alerts


• keyword checking in websites monitored (testing)


• mobile version


• monitoring from multiple locations (we may need your help, will be sharing more details later)

A little story of Uptime Robot:

I'm sharing a little office with Daniel Rimille of SSLmatic which we're building a complicated web application for a while.

The application is something totally different from Uptime Robot but it needed to monitor websites/IPs it worked with & we created a module for this which worked awesome.

It was my idea to convert this module into a website uptime monitoring service.

Daniel was a little uncommitted as he thought this would take much time & we would be missing our schedule for the application we're building. I thought this was an opportunity to see how it would scale, help us improve ourselves in means of usability, handling support requests, etc.

And I claimed to build it in only 2 days, had a bet (lost a dinner), but completed in 4 days. It took 8 extra days for us both to polish it & here it is.

We loved what we created & will be updating/improving Uptime Robot frequently as there are so many similarities with what we're already building.
