What is SteamVault?

SteamVault provides a complete offline solution for managing Steam depot manifests and Lua configuration files. It acts as a localized vault for your game configurations, automatically generating and maintaining the manifest and depot key mappings needed by tools like OpenSteamTool. This allows you to own steam games for completely free.

No Steam client, no Steam account, no API key required. Everything is sourced from publicly available data.

How It Works

+---------------+     +----------------+     +-------------------+
|  Steam CDN    |---->|  SteamVault    |---->|  Your PC          |
|  (Public)     |     |  (Generates)   |     |  Steam\config\    |
+---------------+     +----------------+     +-------------------+

1. SteamVault queries the public Steam CDN for depot manifests and game metadata
2. It generates .lua configuration files and caches .manifest files
3. Files are placed directly into your Steam\config\lua and Steam\config\depotcache directories
4. OpenSteamTool then uses these files to enable offline mode

Installation

Download Pre-Built Release

The easiest way to get SteamVault is to download the latest pre-built executable from the Releases page.

Download Latest Release

Simply extract the ZIP and run SteamVault_v2.0.0.exe. No installer needed.

First-Run Wizard

On first launch, SteamVault will guide you through a one-time setup:

1. Auto-detects your Steam installation directory via the Windows Registry
2. Displays the detected path — you can verify or browse to change it
3. Installs OpenSteamTool by copying 3 lightweight DLLs into your Steam folder
4. Creates the necessary config\lua and config\depotcache directories
5. If OpenSteamTool files already exist, it detects them and skips straight to the app

Once installed, the wizard never appears again. Your settings are saved in %APPDATA%\SteamVault\settings.json.

Usage Guide

Dashboard

• Download Game by AppID — enter a Steam AppID and download its manifests and Lua configs instantly
• View your download history with game names, header images, and status badges
• All downloads are saved to Steam\config\lua (Lua files) and Steam\config\depotcache (manifest cache)

My Games

• Scan your Lua folder to discover all locally stored games
• See live update status for each game: Up to Date or Update Available
• Update All or update individual games — fetches the latest depot manifests automatically
• Filter and search by AppID or game name with fuzzy matching

Settings

• Configure the Steam directory, Lua output path, and manifest cache path
• Enable automatic background updates — SteamVault starts with Windows and checks for updates every 4 hours
• Sync the depot key database from the latest public key repository on GitHub
• Toggle the ToggleSwitch to enable/disable auto-start

System Tray

• Close the window to minimize to tray (when auto-update is enabled)
• Right-click the tray icon for quick actions: Open Dashboard, Scan & Update, or Exit

Building from Source

Prerequisites

• .NET 9.0 SDK
• Git
• Download the OpenSteamTool Dll files https://github.com/OpenSteam001/OpenSteamTool/releases/tag/v1.4.6-fix

Build Steps

# Clone the repository
git clone https://github.com/Fluxerr/SteamVault.git
cd SteamVault

#Drad and drop the OpenSteamTool.dll,
#dwmapi.dll and xinput1_4.dll into the
#"OpenSteamTools" folder
#and delete the existing empty text file.

# Restore packages and build
dotnet restore
dotnet build -c Release

# Run (development)
dotnet run

Publish (Single-File EXE)

To produce a single, self-contained SteamVault.exe that bundles the .NET runtime, all dependencies, and OpenSteamTool DLLs into one executable:

dotnet publish -c Release -r win-x64 --self-contained true

The output will be a single EXE at:

SteamVault\bin\Release\net9.0-windows\win-x64\publish\SteamVault.exe

Key properties (set in SteamVault.csproj):

• PublishSingleFile=true — packs everything into one EXE
• SelfContained=true — includes the .NET 9 runtime (no separate .NET install needed)
• IncludeAllContentForSelfExtract=true — embeds managed DLLs, JSON data files, and OpenSteamTool native DLLs into the EXE
• IncludeNativeLibrariesForSelfExtract=true — ensures native DLLs like dwmapi.dll and xinput1_4.dll are also bundled

Distributing: The single EXE file can be shared directly — no installer, no ZIP extraction, no runtime prerequisites required.
