Yes, it's open source but the project hasn't published an update in
almost 2 years.

Accordingly, it is not being actively developed...

There are other tools, some very inexpensive, which are much more
actively updated to reflect the latest changes/enhancements in the
engine, and are therefore better solutions/options.
