This was my mini-project in my college, the use of the website was you can register your website and it will check whether your website runs without any fails. if something happens then it will mail to the respective mail you have given.
I think so many website owners cant be able to keep an eye on their website whether it was running or not for them it will help a alot.
If you want to try the project , during testing goto dist folder to launch the website.
Thankyou :)
