What it is
Zephyr is a free desktop mod manager for browsing and installing mods, then switching between game mod profiles. It supports about 200 games out of the box and combines Thunderstore and CurseForge browsing in one search. Mods are deployed by copying them, and 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. Zephyr also includes an Archipelago multiworld randomizer with Python bundled, a BepInEx configuration editor, and gamepad navigation throughout the interface. Customization includes seven themes, custom fonts and colors, and seven language options. The app is available for Windows, macOS, and Linux, and is distributed 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.
