REDdeck
REDdeck is the EDGE platform’s mod manager for Cyberpunk 2077. It runs inside VS Code (and inside REDcode, which is built on VS Code) and looks after the mods you download: it keeps them, puts the ones you want into the game, takes them out again, and tells you when two of them fight over the same thing.
What it’s for
Cyberpunk 2077 has no built-in list of mods. A mod is a set of files dropped into the right folders inside the game folder: archives in one place, scripts in another, plugins in a third. Doing that by hand works for two or three mods. With twenty, you lose track of which file came from which mod, removing a mod means hunting for its files, and a game update can quietly break everything.
A mod manager does that bookkeeping for you. REDdeck:
- keeps your mods in a library outside the game folder, so turning a mod off doesn’t mean deleting it;
- deploys the mods you switch on into the game folder, and records every file it puts there;
- undoes a deploy exactly, removing only the files it placed;
- shows conflicts when two mods change the same thing, and lets you choose the winner;
- checks Nexus Mods for updates and downloads them for you.
Why you might want it
| If you… | REDdeck gives you |
|---|---|
| Find other mod managers confusing | One list of mods and four verbs: add, turn on or off, deploy, remove. Plain words, and no profiles, staging, purges or rules to learn |
| Worry about breaking your game | Every deploy is recorded in a manifest and can be undone. REDdeck never deletes a file it didn’t put there |
| Have mods that clash in strange ways | REDdeck sees conflicts inside mod archives, which file-based managers like Vortex can’t see, and explains who wins |
| Already use Vortex | A one-click import of your Vortex mods. Vortex keeps its copies, so you can go back |
| Want an AI assistant to manage mods for you | A command line and an MCP server with the same verbs, so Claude or another agent can list, add, switch and deploy mods, asking you before it touches the game |
| Make mods in REDcode | Your project’s packed output becomes a mod that refreshes every time you pack |
How it fits into EDGE
REDdeck is the Deploy stage of the EDGE platform. It works on its own, and other toolkits add to it when they’re present:
| Toolkit | What it adds to REDdeck |
|---|---|
| REDbridge | Reads inside mod archives, so REDdeck can show archive-level conflicts. REDdeck downloads and updates it for you |
| REDcode | A REDcode project can become a REDdeck mod, and REDdeck mods can feed files back into a project |
| Claude and other agents | REDdeck’s MCP server lets an AI assistant manage your mods |
Status
REDdeck is at version 0.19 and manages its developer’s game on two PCs. It isn’t on the VS Code Marketplace yet; it installs from a file on its releases page. Nexus sign-in through the browser is built and waits for Nexus to register REDdeck; until then you paste a personal API key, which works the same way.
