No commits since 2014, A beta version and it says it was made by OutCast3k.

It's possible that it was by OP and then he changed the repository because apparently, the first version released on the new repository is 1.1 while the link you're referring to is 1.0.

I don't see why you would use something unstable and that might have bugs though. So If you're planning to do that, make sure to check the source code and not just run it as well, just to be sure that it doesn't contain anything malicious.
