Regularly I get questions about the availability of ZW-Scoring for Web, Linux or MacOS.
Leo Eggink has built ZW with Visual Basic 6 specifically for the Windows platform. Right now I am converting it to VB.Net, still on the Windows platform, which is quite a task in itself due to the many differences between VB6 and VB.net. The latter is more or less Object Oriented, which I try to use as much as I can. I hope this will make a future move to rebuilding ZW in the Java language more easy. This is needed before thinking about releasing versions for Linux and MacOS.
ZW on the Web is also something I am thinking about, but at the moment this has no priority.
As of March 1st 2018, Leo Eggink has transferred the maintenance of ZW to Gerhard Bouma and Eric Mehlbaum.
The intention is to release an updated Windows 10 version 5 in the late spring/early summer of 2018.
