How it works

Three steps. That's it.

1

Point it at your game

Corkscrew auto-detects CrossOver, Whisky, Proton, and Lutris bottles on macOS, SteamOS, Ubuntu, Fedora, and more.

2

Browse & install mods

One-click Nexus Mods downloads. FOMOD wizards handled natively. Drag to reorder.

3

Hit play

SKSE, Engine Fixes, and load order sorted automatically. Launch straight from Corkscrew.

The problem

macOS, SteamOS, and Linux gamers don't mod Skyrim. Not because they can't run it—because they can't manage mods.

MO2 and Vortex are Windows-only. Running them through Wine or Proton is fragile, slow, and breaks on every update. Nobody wants to manage a 300-mod load order inside a virtual desktop on their Mac or Steam Deck.

The fix

A mod manager that actually runs here.

  • Native binary for macOS (Apple Silicon & Intel), SteamOS, Ubuntu, Fedora, Arch, and more. No Wine wrapper, no Electron.
  • One-click Nexus SSO. Download with manager, full API.
  • SKSE, Engine Fixes, Address Library auto-deployed.
  • LOOT plugin sorting and conflict detection built in.
Features

Everything you need, nothing you don't.

Drag, drop, done.

Install from Nexus with one click or drop archives in. FOMOD wizards, BSA unpacking, and conflict resolution handled natively. Sort hundreds of mods with real-time search and category filters.

Plugin sorting that works.

Integrated LOOT engine sorts plugins automatically. See master dependencies, detect conflicts, fix load order before it crashes. Drag to override when you know better.

Engine Fixes, Auto-Deployed

Custom Wine-compatible SSE Engine Fixes patches 60+ crash sites with VEH recovery. Deployed automatically, updated silently.

CrossOver, Whisky, Proton, Lutris

Auto-detects your Wine compatibility layer on macOS, SteamOS, and Linux. Works with Steam, GOG, and manual installs across all distributions.

Crash Logs, Decoded

Built-in crash log viewer with stack traces mapped to your mod list.

Open Source, GPL-3.0

Every line is public. No telemetry, no accounts required. Built by a modder who got tired of waiting for someone else to solve this.

Profiles & Presets

Swap setups instantly. Vanilla, lightly modded, 400-plugin chaos.

Fast because it has to be.

Corkscrew manages thousands of files across a Wine/Proton boundary on macOS, SteamOS, and Linux. Every millisecond of overhead is one you notice. That's why the backend is Rust and the frontend is Svelte—the two fastest options in their class.

Jan 2026

First commit

Can a Tauri app install a Skyrim mod into a CrossOver bottle on macOS? Turns out, yes. The prototype handled archive extraction, file deployment, and Wine prefix detection in under a week.

Jan 2026

Nexus Mods integration

Full SSO authentication via WebSocket, NXM deep-link handling, and download-with-manager support. One-click installs from the Nexus website straight into your Wine bottle.

Feb 2026

FOMOD installer

Complete XML wizard implementation with conditional flags, image previews, multi-step flows, and nested option groups. Handles the same FOMOD configs that MO2 and Vortex use.

Feb 2026

SSE Engine Fixes for Wine

A custom fork of SSEEngineFixesForWine—a Wine-compatible SKSE plugin that patches 60+ crash sites with vectored exception handling, sentinel page recovery, and code-cave hooks. Auto-deployed by Corkscrew on every launch.

Feb 2026

LOOT integration

Native libloot FFI binding for plugin sorting, master validation, and conflict detection. 3,700+ metadata entries. Sorts your entire load order in milliseconds.

What's new.

"I built Corkscrew because I wanted to mod Skyrim on my Mac and there was literally nothing that worked. MO2 through Wine was a nightmare. So I learned Rust, learned Tauri, reverse-engineered the game engine for Wine compatibility, and built what I needed. Whether you're on macOS, SteamOS, or any Linux distro—if you're here, you probably wanted the same thing."
