The record

Product: NetRadiant is a free, open-source, brush-based 3D game level editor.
Game support: It supports many games, including Xonotic and Unvanquished.
Maintainers: It is maintained by a community of gamers, mappers, modders, and game developers.
Origins: NetRadiant is historically a fork of Id Software’s GtkRadiant project.
Development: The project is driven by Xonotic and also receives support from Unvanquished.
Downloads: The download page lists builds for Linux 64-bit, Windows 32-bit and 64-bit, and macOS 64-bit.
Additional OS: The download page also lists a FreeBSD 64-bit build.
Compatibility: The download page describes first-class compatibility with Xonotic and Unvanquished, and support for about 30 other games, with support varying by game.
Included tools: The listed builds include daemonmap for Unvanquished navmesh generation and Smokin’ Guns q3map2 patches.
Linux requirement: Linux users need a working GTK2 and OpenGL environment to use the listed builds.
Windows rendering: Windows users can enable optional Mesa3D rendering; the page describes a software-rendering workaround for some older Intel chips on Windows 10.
Mapping support: The listed builds support released Xonotic files without requiring an extra mapping support package.
Support caveat: A 2022 project post says macOS support was new and still rough, with possible multi-screen configuration problems.
Build provider: The download page says builds are produced from time to time by illwieckz in an effort to provide up-to-date builds.
