Spec score 7.1 #21 of 30 in Game Trainers

What it is

TrainerBridge is a free, open-source Linux application for running standalone Windows trainers with Steam games through Proton. It examines Steam libraries, identifies each game’s Proton version and compatdata prefix, then starts a trainer inside the matching Proton environment. You can import and manage one trainer executable for each Steam game and launch the game and trainer together or independently. Steam installations delivered as native packages, Snap, or Flatpak are supported. An optional Protontricks frontend can place common runtimes, fonts, settings, and applications into a game prefix. Before prefix changes, TrainerBridge can create backups using copy-on-write folders on compatible Btrfs filesystems or compressed .tar.zst archives elsewhere. Downloads include an x86_64 AppImage and portable .tar.xz archive with SHA-256 checksums. It does not supply trainers, alter game files, or bypass anti-cheat systems. Prefix component compatibility varies by game, prefix state, Proton version, and Winetricks recipe.
