Legio is a desktop game launcher for Windows and Linux. Import games from Steam or add them manually, configure how each game launches, and keep your library and playtime in one place.
- A Steam account for each game. If you use multiple accounts, assign the right one to each title. Legio asks before restarting Steam to switch accounts when needed.
- Per-game launch settings. Run native Linux games or Windows games through Proton, GE-Proton, or Wine. Configure prefixes, launch arguments, environment variables, and DLL overrides on Linux, or native launch options on Windows.
- Flexible game import. Detect your Steam library or add games and executables manually.
- Themes you can make your own. Choose from built-in palettes, edit colors, set image or animated backgrounds, and save your own themes. Import and export themes as JSON.
- Hyprland transparency. Enable a transparent Legio window on Hyprland and adjust the surface opacity. Background blur is controlled by your Hyprland rules.
- Playtime at a glance. See recently played games, tracked playtime, and a calendar of your activity.
Legio includes an Online Fix launch option for compatible games. It is a launch configuration feature: Legio does not provide or distribute game files or Online Fix files.
Legio does not support or promote piracy. Use this option only with a legitimately purchased copy of the game and for offline play, in accordance with the game's license and applicable laws. Users are responsible for their use of this feature; Legio accepts no responsibility for misuse.

.debor.rpm. - Arch Linux / AUR:

Steam is required for Steam integration. For Windows games on Linux, see runner setup.
Add an HTTPS catalog in Settings > Sources. You can install multiple sources, refresh their cached releases, and remove them individually. No download source is configured by default.
Hydra sources are also supported. Some source URLs are protected by Cloudflare and cannot be fetched directly by Legio. Download the actual JSON file in your browser, then use Choose JSON file in Sources to select its local path. Use a JSON file, not a saved challenge page. Local refresh rereads that file; it does not download a newer copy. See Hydra compatibility for supported downloads and limitations.
After starting Legio once, opening a link such as
legio://add-source?url=https%3A%2F%2Fcatalogo.example%2Fgames.json
opens the launcher and adds the catalog. The browser may ask to open Legio.
AppImage users need xdg-utils and desktop-file-utils for protocol registration;
keep the AppImage at a stable path, or run it again after moving it.
Follow Development setup for Linux and Windows
prerequisites, then run corepack pnpm install --frozen-lockfile and
corepack pnpm tauri dev. Development runs use a separate application profile
and do not modify the installed launcher's data. See Contributing
for checks and the pull request workflow.
