Modern Proton Prefix management tool
Project description
Prefixer is a tool for managing Steam Proton prefixes, alternative to protontricks with a friendlier interface, faster responses and modular approach.
Why this?
Prefixer:
- includes fuzzy name matching, so you don't have to remember IDs
- is up to 40 times faster than legacy methods by modifying files directly (no wineserver)
- instead of "verbs" uses a declarative json5 format for tweaks, so you can share your work
- includes built-in first-class Steam support
Overriding winhttp for BepInEx, compared to protontricks
Usage
prefixer 'cyberpunk' tweak libs.d3dx9.47 # installs d3dcompiler 47 in Cyberpunk 2077
prefixer 'fallout new' run ~/Downloads/fonv_patcher.exe # runs the patcher for Fo:NV
prefixer 'subnautica' tweak loaders.bepinex # installs BepInEx 5 for Subnautica
prefixer 'Balatro' openpfx # opens the wineprefix folder in your file manager
Alongside more! Run prefixer --help or prefixer --list-tweaks for everything!
Installation

install prefixer with your favorite AUR helper, for example:
