What Zephyr is
Zephyr is a free desktop mod manager for browsing and installing game mods, then switching between mod profiles. It supports about 200 games out of the box and combines Thunderstore and CurseForge browsing in one search. The app is available for Windows, macOS, and Linux, and installs mods by copying them. Users can share a profile code or link so friends can reproduce a setup. Optional cloud sync requires signing in with Discord and enabling the feature in the app. Zephyr also includes an Archipelago multiworld randomizer with Python bundled and an editor for BepInEx plugin configuration files. Gamepad navigation works throughout the interface. Users can choose from seven built-in themes, customize fonts and colors, and use one of seven languages. The desktop app is open source under the GPL-3.0 license. The maker says that without sign-in, personal data stays on the device and mod metadata requests are anonymous. With cloud sync enabled, profile archives and metadata are stored with the maker's hosting provider in France. The Windows build is not code-signed and the macOS build is not notarized.
