What it is

RimModManager arranges RimWorld mods on Linux, macOS, and Windows. Detection covers Steam, GOG, Proton, Wine, Flatpak, and standalone installations. You get profiles, backups, conflict checks, dependency sorting, and built-in Workshop tools. Workshop downloads depend on SteamCMD, and scanning especially large collections can take time.

Good, and not so good

  • Works with Steam, GOG, Proton, Wine, Flatpak, and standalone installations
  • Profiles, automatic backups, conflict detection, and dependency sorting
  • Built-in Workshop browser with queued and batch downloads
  • Symlink activation leaves mod files unchanged
  • Available on Linux, macOS, and Windows
  • Workshop downloads need SteamCMD
  • Scanning collections of 500 or more mods may take time
  • Proton and Wine rely on copy mode rather than symlinks
  • Embedded Workshop browsing needs optional PyQt6-WebEngine

Who it suits

RimWorld players managing profiles across different install types Groups that need repeatable mod lists and backups Players who want built-in Workshop collection tools

RimModManager is a sensible pick for RimWorld players who manage more than one installation type or maintain profiles for a group. It combines load-order controls, conflict detection, backups, imports, and Workshop browsing in one free application. Workshop downloads still depend on SteamCMD, and collections of 500 or more mods can take time to scan. Choose it when those conditions fit your setup and you want symlink-based activation on supported boundaries.

Questions

What game does RimModManager manage?
It handles RimWorld mods installed through Steam, GOG, Proton, Wine, Flatpak, or standalone setups.
Which operating systems are supported?
Linux, macOS, and Windows are supported.
Does it include mod profiles and backups?
Yes. Profiles can be saved and loaded, and the app automatically backs up before major changes.
Do Workshop downloads require SteamCMD?
Yes. SteamCMD is needed for Workshop downloads; the wiki says anonymous downloads do not need a Steam login.
Can it detect mod conflicts?
Yes. The conflict resolver finds conflicts and provides fix suggestions.
Does it change the original mod files?
Activation uses symlinks and leaves the mods themselves untouched. Proton and Wine use copy mode because symlinks do not work across those boundaries.
Can I import or export a mod list?
ModsConfig.xml can be imported and exported, and a text mod list with Workshop links can also be exported.
What happens with very large collections?
According to the wiki, collections containing 500 or more mods may need extra time to scan.
