Corkscrew vs Prismo

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.

Prismo publishes Zephyr, a free, open-source desktop mod manager for Linux, macOS, and Windows. Zephyr lets users browse, install, update, and organize mods for about 200 games. Built-in access combines Thunderstore and CurseForge browsing. Users can create and switch between profiles for each game, then share a profile through a code or link. Optional cloud synchronization uses Discord sign-in to synchronize profiles across devices. The app also includes an Archipelago multiworld randomizer with a bundled Python runtime, a configuration editor, gamepad navigation, and seven languages. Without sign-in, profiles, configuration files, and preferences remain on the device, while public mod metadata is requested anonymously. Cloud-enabled profile archives and metadata are stored with Prismo Studios’ hosting provider in France. Zephyr is licensed under GPL-3.0, with source code on GitHub. Installers include Windows .exe, Linux AppImage and .deb, and macOS .dmg files.
