This Safari extension allows you to shorten URLs in just one click right from your browser!
There are 2 options:
1. You can click the extension's toolbar button and the current page URL will be immediately shortened and copied into clipboard automatically.
2. You can right-click any link at any website and this link's URL will be immediately shortened and copied into clipboard automatically.
The extension uses the cutt.ly shortener API, the API key is already embedded so you can just install it and use immediately. Additional option is to set your own cutt.ly API key and track your shortens and their visitors through cutt.ly website in this case.
