App-focused OS X Web browser Raven has got off to a flying start in its first three weeks, it seems. The team behind it has announced that 100,000 apps have been installed from its built-in app store.

As we reported when it launched on 10 October, Raven takes an app-style approach to the Web, allowing users to install dedicated interfaces for their favorite sites. The browser launched with a selection of apps which has since been expanded with an extra 50 created by the Raven team. These include Amazon, Tumblr, Wikipedia and even Angry Birds.

The browser itself has received a new update too, featuring tab switching with key commands, the ability to hide the address bar, Web app shortcuts, an OS X Lion-style linen pattern added behind the viewport, along with various UI enhancements.

While the team hasn’t disclosed actual download numbers, the app is still in beta and not available on the Mac App Store, so 100,000 installs of Raven Web apps with the app itself, when there are only around fifty of the apps available, certainly points to a successful launch.

You can try Raven, which is still in beta, by downloading it at raven.io/download.html. An SDK and submission process for third-party developers to add their own apps is on the way.
