It's customizable.
With the powerful XKit Control Panel, you can easily customize the extensions you have, get new extensions from the Extension Gallery for free, and disable or completely remove extensions you don't need or like.

Automatic Updates
You know when Tumblr changes something, extensions suddenly stop working, and you need to update them manually? Not with XKit. With built-in Automatic Updates, when a new update is released, you get it in less than an hour.

Lots to choose from
The Extension Gallery allows you to download a great variety of extensions, from Blacklist to Themes. You can shorten long posts on your dashboard, add widgets to it, check who unfollowed you, and much more.

Free and open
XKit is provided entirely free of charge, and the framework is open to anyone who wants to create extensions, themes and widgets for it.
