alpha release available here: http://spooky.github.io/unitdb
Note that this still has quite a few things that need to be done (starting with the essence - unit details) but the unit list is there and the overall 'feel' - so I'd like to see how this thing is received.
The performance needs work, so be patient until everything loads - there are quite a few things that need to be pulled and this is a 'preview' version, so no optimizations were done.
