Hi,
Over the last months, with the friendly support of Pegasus Spiele (the german distributor of Shadowrun), I have been working on a character generator software for SR6. It is a desktop application like Chummer, but implemented in Java and running natively on Windows, OS X and Linux.
To be precise: It is a multi-system character generation software called "Genesis" and Shadowrun 6 was the latest addition. Other RPGs supported include Coriolis and Space 1889 (Ubiquity)

More details in the project
blog.
Since yesterday I declared it ready for Beta testing (and I am very nervous about it ) - meaning it surely does have bugs, but I need real users now to find and squash them.
If you want to help testing (or simply give it a try), start
here. But please don't report bugs in this thread - we have an issue tracker for that, so reports don't get lost.
The software is free and like Chummer and the source code will be available for contributions. But I am not quite there yet.
P.S.:
And since the question always comes: No, it is not online and it does not run on mobile. This may come somewhere in the future, but right now that is not possible.
