You guys should try this one: https://www.designconnected.com/connecter/
IMO, this one is better than PM (commercial one), has tags capabilities (which is really important, for me at least) and quite fast in assets tracking.
More of it, it works on another platform like Cinema 4D and the one I read also in Substance Painter. Its database handling is also opening the possibilities for another purpose, like making your own movies library, although may not be perfect like EMDB. And the best of it all, its FREE.
