This is probably the best AppSumo deal for $14. Upon signing up, you will be presented a dashboard with the list of links, spaces, domain and pixels. This allows you to have a glance view of everything you require for a link shortener. It comes with the default domain or you can use your own domain. Adding your domain is pretty easy too! All you need to do is just to point A record to the IP and it will work flawlessly.

I have been using bitly (mind you that the basic plan is costing $29 a month), heck I coded my own URL shortener before but managing it is pretty tough. I am glad that this eventually took away the stress of self-managing links. Lifetime deal that is too hard to resist!
