What it is

Prismo publishes Zephyr, a free, open-source desktop mod manager for Linux, macOS, and Windows. Zephyr lets users browse, install, update, and organize mods for about 200 games. Built-in access combines Thunderstore and CurseForge browsing. Users can create and switch between profiles for each game, then share a profile through a code or link. Optional cloud synchronization uses Discord sign-in to synchronize profiles across devices. The app also includes an Archipelago multiworld randomizer with a bundled Python runtime, a configuration editor, gamepad navigation, and seven languages. Without sign-in, profiles, configuration files, and preferences remain on the device, while public mod metadata is requested anonymously. Cloud-enabled profile archives and metadata are stored with Prismo Studios’ hosting provider in France. Zephyr is licensed under GPL-3.0, with source code on GitHub. Installers include Windows .exe, Linux AppImage and .deb, and macOS .dmg files.

  • Supports about 200 games out of the box
  • Browses Thunderstore and CurseForge together
  • Profiles can be shared by code or link
  • Includes automatic updates and built-in mod sources
  • Open source under GPL-3.0

Who it suits

Zephyr suits players who manage mods across supported games and want profiles, sharing, or optional cross-device synchronization. It also fits users who prefer an open-source desktop application on Linux, macOS, or Windows.

Verdict

Zephyr combines multi-game mod management, profile controls, and two major mod sources in one free desktop application. Its local-first behavior and open-source license are clear, while cloud synchronization is optional and requires hosted storage.
