PizzaTools injects game manifests into Steam's depot cache, making any game archive instantly appear in your library. No download needed.

Provide a game's App ID (from SteamDB). PizzaTools generates or extracts Lua files and AppManifest files in the exact format Steam expects.
Manifests are placed into Steam directories. The local Steam client sees the game as "owned" and displays it in your library.
Steam's content depots authenticate the manifest format, not the license. PizzaTools emulates valid requests to pull files from Valve's official CDN.
Most games check Steam for ownership. PizzaTools tricks these basic DRM checks. For online features, use OnlineFix patches.
