TrainerBridge
What TrainerBridge is
TrainerBridge is a free, open-source Linux application for launching standalone Windows trainers alongside Steam games running through Proton. It scans Steam libraries, identifies each game's Proton version and compatdata prefix, and starts a trainer in the matching environment. Users can import and manage one trainer executable per Steam game, then launch the game and trainer together or separately. It supports Steam installed as a native package, Snap, or Flatpak.
An optional Protontricks frontend can install runtimes, fonts, settings, and applications into a game's prefix. TrainerBridge can back up a prefix before changing it, using copy-on-write folders on compatible Btrfs filesystems or compressed .tar.zst backups elsewhere. The recommended download is an x86_64 AppImage; a portable .tar.xz archive and SHA-256 checksum files are also provided. The application does not include or download trainers, alter game files, or bypass anti-cheat systems. Compatibility of prefix components depends on the game, prefix state, Proton version, and Winetricks recipe, and GE-Proton does not guarantee success. The maker advises against using trainers in online or competitive multiplayer games.
