Xbox Live Friends

Xbox Live Friends does not work with the current Xbox Live website. I don't plan to update it, but the source is available here.

What is it?

Xbox Live Friends (XLF) lets you see your friends’ status updates, check your messages and manage your Xbox Live account from in a comfy Cocoa form.

XLF was originally created over at Mindquirk.

Friendz is another desktop client for Xbox Live and is maintained for site changes.
