Boxedwine vs WineZGUI

Boxedwine is an emulator for running 16-bit and 32-bit Windows applications on Windows, Mac, Linux, and in a browser. It runs a 32-bit version of Wine while emulating the Linux kernel and CPU, and is released under the GNU General Public License v2. The browser build uses Emscripten, including WebAssembly and asm.js. Boxedwine supports multiple Wine versions from 1.6 to Wine 5.0. Its web version uses memory storage by default, so changes to d:/ are discarded when the browser tab closes. Users can configure Dropbox storage or use local storage, whose limits depend on the browser and operating system. The web build can accept a dropped directory to list executable files and can be configured with URL parameters. Documentation warns that on-demand loading of large files can block the interface or potentially crash the emulator, and requires server range-request support. The site also provides online demos for selected applications and games, including AbiWord, Age of Empires, and Caesar III, plus user and developer documentation.
