What CPMM is

CPMM is a free, open-source Windows manager for Cyberpunk 2077 mods and core game settings. It supports standard installation as well as advanced or manual methods, including mods placed in folders such as mods, dlc, bin, engine, r6, and plugins. ZIP and 7-Zip archives are supported, while password-protected archives are ignored. An archive can include modmanager.json metadata with a mod name, author, version, category, and priority. Users can choose a custom backup path, and the manager can launch the game with optional executable arguments. Multiple language packages are available. CPMM is built with C# and WPF on .NET 5; the standard package requires the .NET 5 x64 runtime unless a self-contained package is used. The project is distributed through Nexus Mods and is licensed under GNU GPL-3.0. Its maker describes it as beta software, warning that some functions may not work. File deletion may not always work, so changes require caution.

Who it suits

It suits Windows players managing Cyberpunk 2077 modifications, settings, archives, and backups. Users should be comfortable with beta software and the stated .NET runtime requirement.

What it does well

  • Supports standard and manual mod installation
  • Handles ZIP and 7-Zip archives
  • Offers custom backup locations
  • Can launch the game with arguments
  • Open source under GNU GPL-3.0

What to know first

  • Password-protected archives are ignored
  • Beta software may have nonworking features
  • File deletion can be unreliable

Verdict

CPMM covers installation, metadata, backups, and launching for Cyberpunk 2077 mods. Its beta status and unreliable deletion mean users should manage files carefully.
