Zephyr
What Zephyr is
Zephyr is a desktop mod manager for finding and installing game mods, organizing them into profiles, and switching between those profiles. It supports about 200 games out of the box and brings Thunderstore and CurseForge browsing into one search. Mods are deployed by copying them, and players can share a profile code or link so a friend can reproduce a setup. The app also includes an Archipelago multiworld randomizer, with Python bundled for generating seeds, and an editor for BepInEx plugin configuration files. Gamepad navigation is available throughout the interface. For customization, users can choose among seven built-in themes, adjust fonts and colors, and use one of seven language options. Zephyr runs on Windows, macOS, and Linux and is open source under the GPL-3.0 license. Cloud sync is optional: users sign in with Discord and enable the feature in the app. 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 installation guide says the Windows build is not code-signed and the macOS build is not notarized.
