CrossHook review
An open-source Linux launcher for reusable trainer profiles, Proton selection, and diagnostics.
Reviewed by iTechGuides Editors · Editorial team · Updated Oct 2026
CrossHook is an open-source Linux desktop launcher for running game trainers alongside Steam and Proton games. It is aimed at Linux players who want reusable, per-game trainer profiles rather than repeatedly configuring launch commands. The application discovers Steam libraries, installed games, App IDs, Proton versions, and compatibility paths. It supports Linux desktops and Steam Deck systems, with Flatpak as the current distribution format.
Its strongest area is launch flexibility. A profile can use Steam App Launch, direct Proton execution, or native Linux execution, while Proton version selection and compatibility information help organize games that need different runtime choices. Dry-run launch previews provide a way to inspect commands before starting a game. CrossHook also connects with Steam, Proton, Steam Deck, and Flatpak, making it a focused fit for Linux gaming setups built around those components.
Diagnostics and portability add practical value for more involved configurations. Profiles can be exported to shell scripts and desktop entries, and diagnostic bundles can be exported when reviewing or sharing configuration information. CrossHook is a good choice for Linux users who want a structured trainer launcher with multiple execution paths and inspectable profiles. It is less suitable for users on macOS or other platforms, and for anyone expecting automatic updates. Users should also expect the current release model to center on Flatpak bundles rather than a broader set of installers.
