I recently installed Lessn and then Lessn More to take control of my own short links. Lessn is a very simple URL shortener that is hosted on my own domain.
I registered upton.in to serve my short links. I chose the “.in” TLD because it’s short and common. I do wish there was an “.on” TLD so I could register upt.on, but I like the connotation of “in”. As I said on Twitter the other day, it can mean “Internet, inside, come in, infinity, interesting” among other things.
Lessn also integrates nicely with Mint, which I recently started using. I plan to write more on that shortly.
