LuaShareX

Export licensed Steam games as .lua files — app token, depots and decryption keys included.

Download

Grab the latest release from GitHub Releases:

• LuaShareX-Setup-v*-win-x64.exe — installer (recommended, per-user, no admin)
• LuaShareX-v*-win-x64.zip — portable, unzip and run

Requires Windows 10/11 x64, the .NET 8 Desktop Runtime, and Steam.

The app checks for updates automatically on startup (and via the header button) and installs them from GitHub Releases.

Modes

• SteamKit2 — sign in with QR code or username + password (Steam Guard supported). Lists your full owned library with ownership tokens.
• Remembered accounts — choose an account under Accounts on this computer and click Continue with selected account. Uses Steam's remembered Windows login, or a login previously saved by LuaShareX. Use Refresh after adding an account in Steam. If its login is missing, expired or revoked, use QR/password instead.
• Local (account-free) — reads config.vdf, stplug-in/*.lua and every appmanifest_*.acf across all library folders. No login.

Multiple accounts are supported, with one active account at a time. Switch account keeps remembered logins and clears the previous account's library and pending login before opening the account picker. Logout forgets only the current account's LuaShareX login; it does not sign out of Steam or remove Steam's remembered login. Accounts added with QR/password also appear in the picker.

Steam's local login must be readable by the same Windows user who saved it. LuaShareX reads loginusers.vdf and %LOCALAPPDATA%\Steam\local.vdf without modifying them. Local token parsing is not an official SteamKit2 API and may need updates when Steam changes its format. Saved LuaShareX refresh tokens are encrypted with Windows DPAPI per account in %APPDATA%\LuaShareX\accounts.json. The old token.txt is migrated when its account can be identified, then removed after successful encrypted storage. No password is saved.

Export format

One game exports as <appid>.lua; selecting several exports a .zip with one <appid>.lua per game. Depot keys are fetched lazily at export time, only for the games you select.

Build

dotnet build LuaShareX.csproj -c Release

Run the Windows regression checks (synthetic accounts, no Steam login):

dotnet run --project Tests/LuaShareX.Tests.csproj -c Release

Add -- --render to render the real login XAML with synthetic accounts to Tests/bin/Release/net8.0-windows/login-preview.png.

Release

Push a tag like v1.0.0 — the release workflow builds the win-x64 zip and publishes the GitHub Release the updater consumes.
