Everything You Need to Know
Q:What is SteamTools and how does it relate to Watt Toolkit (Steam++)?
SteamTools, Steam++, and Watt Toolkit are historical names of the same open-source project. All .lua and key.vdf manifests generated on this site are fully cross-compatible with all versions of the client.
Q:Is it safe to use SteamTools generated manifests?
Yes. SteamToolsApp compiles clean, open-source Lua scripts and standard key.vdf files without requiring your Steam password, tokens, or Web API keys. No system DLL injection is performed.
Q:Where do I put the downloaded .lua and key.vdf files?
Extract the downloaded ZIP package and drop both files directly into your SteamTools install directory. Then restart SteamTools and Steam.
Q:Does SteamTools work on macOS and Steam Deck?
Yes! SteamTools provides native builds for macOS (compatible with M1/M2/M3/M4 chips and Intel) as well as Linux distributions and Steam Deck (SteamOS).
Q:Why does my game not appear in Steam after copying files?
Ensure you completely closed and restarted both SteamTools and Steam. Files must be located in the root installation folder, not inside subfolders. Also verify that you are logged into your Steam client.
