Hyperion is a Linux game launcher focused on running Windows titles with Wine and community Proton tools through a single desktop interface.

It helps you manage manually added games, organize your library, choose compatibility runners, inspect logs, adjust launch settings, and work with Proton and Wine environments without doing everything from the terminal. Hyperion also includes tools for dependency checks, environment configuration, sandbox-related options, metadata handling, and Proton version management for advanced users who want more control over their setup.

Current support is centered on manual games, Epic-based workflows, GOG-style setups, and custom launcher use. Steam-related workflows are still experimental and should be treated as work in progress.

Hyperion does not bundle Steamworks binaries or ship Valve Proton inside the app package. It works with the user’s own local setup and can integrate with community compatibility tools such as GE-Proton where available.

This project is aimed at Linux players who want a cleaner way to launch, organize, and troubleshoot non-native games from one place.
