Corkscrew vs RimModManager

Corkscrew is a free, open-source mod manager for Linux and macOS. It supports Skyrim and lists Fallout 4 support; Starfield is described as coming soon. Its built-in mod source access includes Nexus Mods downloads using OAuth 2.0 with PKCE, NXM links and Nexus SSO. Users can install Nexus mods with one click, add archives, run FOMOD wizards and reorder mods by dragging. Profiles let users switch between vanilla, lightly modded and large-plugin setups. Plugin tools include LOOT sorting, master validation, conflict detection and dependency views. Corkscrew also supports Wabbajack modlists through a seven-phase installation pipeline. Custom SSE Engine Fixes patches cover more than 60 crash sites and deploy automatically. The project requires no account and uses no telemetry. It is licensed under GPL-3.0, and its page lists a 17 MB download. Support links include GitHub, Issues and Support on Ko-fi.

RimModManager is a free, open-source tool for organizing RimWorld mods across Steam, GOG, Proton, Wine, Flatpak, and standalone installations. It offers platform-specific detection, profiles, and drag-and-drop ordering, as well as search, filters, and dependency sorting. Mod activation uses symlinks and does not alter the mods themselves; for Proton and Wine, it uses copy mode instead. A conflict resolver identifies clashes and offers fix suggestions. Its built-in Steam Workshop browser supports queued and batch downloads, collection parsing, update checks, and subscriber and rating details. Workshop downloads require SteamCMD, though the wiki says anonymous downloads do not need a Steam login. Users can save and load profiles, with automatic backups before major changes, and import or export ModsConfig.xml. A text mod list with Workshop links can also be exported. RimModManager runs on Linux, macOS, and Windows. PyQt6-WebEngine is optional for its embedded Workshop browser. The wiki notes that collections of 500 or more mods may take time to scan.
