What Windhawk is
Windhawk is free, open-source Windows software for customizing Windows programs through installable mods. Its marketplace lets users browse mods, install them with a couple of clicks, and adjust available options. Each offered mod includes source code for review, while Windhawk’s own source is published in a public GitHub repository under GPL-3.0. The project says it is designed to stay active in the background without noticeable system impact. A command-line interface manages mods and settings, compiles local mod source files, and checks for or installs updates. The official repository accepts mod submissions as pull requests containing a mod source file. Support and discussion are available through GitHub issues and discussions and a Discord channel. Windhawk supports Windows 10 and newer on 64-bit x64 and ARM64 systems. The 2.0 release notes state that 32-bit Windows is no longer supported.
