Hey,
While looking at some projects on GitHub, I came accross one that had a "dependencies up to date badge". This badge was provided by https://www.versioneye.com/ and based on the package.json file of the JS project in question. Since this service also supports Composer, I went ahead and tried using this for Ask.

Also see the page you get when clicking the badge: https://www.versioneye.com/php/ask:ask
Cheers
