Modrex Mod Manager

Website  Discord  SourceKo-Fi

The mod manager for PAYDAY 3, PAYDAY 2, PAYDAY: The Heist, and Crime Boss: Rockay City. Free and open source. Browse, install, and organize mods from ModWorkshop without touching a file explorer.

Already modding by hand? Point Modrex at your game folder. It reads what's already installed and identifies each mod by name, author, and version when that information is available, so your existing setup shows up in the library instead of a pile of folders.

Install in one click

  []Missing dependencies are detected before installation, and those hosted on ModWorkshop can be installed in one click[/]

Loader support built in

SuperBLT, BeardLib, DAHM, mod_overrides, host-mod content packs, and UE4SS Lua sub-mods for PAYDAY 3 and Crime Boss: Rockay City. If a mod needs a loader you don't have, Modrex installs it.
