A direct, strongly-typed GDExtension wrapper for the Steamworks SDK, giving Godot 4 projects a clean singleton API and typed data classes for Steam. Fully functional as a standalone open-source addon, and the base layer for the commercial Toolkit for Steamworks extension.

Works from both GDScript and C#.

What it does

A Steamworks settings dock (Project Settings, Plugins, enable Foundation for Steamworks) lets you configure your App ID, Achievements, Stats, Leaderboards, and DLC visually. A single "Generate Code" button then produces a type-safe SteamGame.gd wrapper and the AutoLoad that initialises it, so every Achievement or Stat name is a real, typo-checked field instead of a raw string.

Covers:

• App: App ID, DLC enumeration, install info, beta names, launch parameters
• User: local identity, persona name, avatar loading
• Friends: friend lists, clan and group membership, rich presence, overlays
• Stats and Achievements: read and write stats, unlock achievements, global percentages
• Leaderboards: find, upload scores, download global, friend, and user entries
• Lobby: create, join, query, and manage lobbies with typed query filters
• Inventory: item definitions, grants, exchange, instance details
• Utilities: IP helpers, Steam Deck detection, floating-point time
• Remote Play: session events, guest invite links
• Timeline: game phase, event markers, state tooltips (SDK 1.61+)
• Game Server: dedicated server initialisation, VAC, anonymous logon
• Matchmaking Servers: server list requests, ping, player and rules queries

All Steam callback events are surfaced as Godot signals on the SteamApi node.

Requirements

• Godot 4.6 or compatible
• A registered Steamworks developer account
• Steamworks SDK 1.63 (download separately from the Steamworks partner portal; not redistributed here)
• Pre-built binaries included for Windows, macOS, and Linux (Debug and Release). A C++ build environment is only needed if you want to build from source.
• Heathen Toolbox, which manages the Game Framework dependency for you — if either is missing, enabling this plugin walks you through fetching them automatically.
