This looks great. I've used uptimerobot on several client projects where I just need a simple up/down notification. The control panel is a little weird, but other than that works really well for its purposes. And it's free.

I was looking for something like this the other day and I found a few open source apps: https://github.com/fzaninotto/uptime and https://github.com/arachnys/cabot

It would be good to find one that I could deploy on app engine.

Using it for about a year without false positive/negative. Usually much more sensitive than the competition for short issue detection.

It is so beautiful, and has the basic functionality of which I use Pingdom for but at a much cheaper rate. Transferring my domains now...

Welcome aboard!

I would still prefer my own website monitoring tool Anturis http://www.anturis.com which is even free if you have only 5 monitors and then the starting price is about $9 per month for nice and effective phone, sms, email alerts and offered troubleshooting.

Beautiful. It makes me want to work much harder on mine (https://www.datasnitch.co.uk).

I like the Google/GitHub integration, the API and especially how you sell its simplicity. DataSnitch is quite simple, but you're one step further.

Congratulations :-)

Thank you! DataSnitch looks cheap and simple too, like it ;)

I would love to see this integrated w/ Pushover.net. Would save $ on SMS fees, and has the ability to send alerts as high priority (ignoring vibrate/silence). Or even just adding an email address instead of an SMS phone # as the alert contact method would work.

Thanks for the suggestion, that's on the long-term roadmap ^^, you can totally add several email address though (with the CC field)

Very slick! Reminds me of a slimmed-down version of the Where's It Up API (https://api.wheresitup.com/), but with monitoring.

(Full disclosure: I've done some work for the Where's It Up folks.)

If you need more than simple HTTP checks (PING, SMTP, WebSocket, etc) you may want to check out NodePing (https://nodeping.com).

Why do they need full access (read and write) to my personal user data on my Github account?

That's a mistake, we don't need more than read-only access to your email, I'll fix this soon, thanks !

Now fixed, only requires email read-only.

Great! Thanks for fixing this so quickly.

Significantly cheaper than Pingdom, as there's significantly less monitoring POPs.
