Corkscrew vs G3M

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.

G3M is a free, open-source desktop manager for GameMaker mods. It can browse supported GameBanana games and install mods from GameBanana, external URLs, local archives, or one-click links. Built-in game entries include DELTARUNE, DELTARUNE Demo, UNDERTALE, UNDERTALE Yellow, Pizza Tower, Sugary Spire, and FRICKBEARS3; users can also add custom games through its Game Manager.

Multiple library profiles can hold separate active mod selections and settings. The Mod Editor combines patches, file replacements, and archive contents, while other tools create and apply patches, merge patch sets, compare files, export diff reports, and convert supported formats. Supported games can launch directly or through Steam where available; Linux users can use PortProton for compatible Windows games. Its Catalog includes themes and plugins, including tools for DELTARUNE saves and custom save folders. Downloads are available for Windows, Linux, and macOS on x86_64 and ARM64 computers. The project states that normal launch mode restores game files after the game closes.
