Web MiniDisc (Pro)
A online cross-platform web app that allows for easy copying of music to a NetMD recorder. Requires a Chromium-based browser. Supports groups and full-width titles.
The Pro fork is under more active development and adds features such as disc export from the RH1 and remote NetMD servers.

Platinum-MD is a modern NetMD writing tool, using similar libraries as Web MiniDisc. Popular with Mac users for ease of install. At the time of writing has experimental support for Hi-MD, but lacks groups/full-width support.
