What's new

• 🕹️ Playable Demo Game (New): A complete multiplayer demo you can run in minutes, with party and session lobbies, colour choice, a level transition, leaderboards, achievements and a Workshop browser. It runs on Godot's own multiplayer API over Steam, with Steam ticket authentication. Included with Toolkit for Steamworks, available through our Direct Code Access and installable through the Heathen Toolbox.
• 🖥️ Game Server, listen or dedicated (New): The Game Server API for listen servers and dedicated builds alike, with a server configuration file that uses the same keys and format as our Unity tools.
• 🌐 Steam Networking and Godot multiplayer (New): Networking Sockets listener and connector, plus a SteamMultiplayerPeer so Godot's high-level multiplayer (RPCs, spawner, synchronizer) runs over Steam.
• 🔐 Authentication (New): Auth session tickets and sessions for client and server.
• 🚌 Game Framework event Bus (New): Every Steam callback is also published on the Game Framework Bus at Heathen.Steam., so other tools can react by address with no direct dependency and no start-order problems.
• 🎮 Steam Input and Workshop (New): Controllers, action sets and glyphs, and Workshop item queries with details, paging and deletion.
• 📖 Data-driven Steam (New): Steam achievements and stats are available as GameplayTags conditions and operations, so an authored rule or a story can read and write them.
• 🧩 Steamworks SDK 1.64 (New): Built against the current SDK.

What's included

• 🏆 Achievements and Stats: Read and write stats, unlock achievements, global percentages
• 📊 Leaderboards: Find, upload scores, download global, friend and user entries
• 👥 Friends and Social: Friend lists, clan and group membership, rich presence, overlays, avatars
• 🎯 Lobbies: Create, join, query and manage lobbies with typed query filters
• 📦 Inventory: Item definitions, grants, exchange, instance details
• 🔧 Steamworks settings dock: Configure your App ID, Achievements, Stats, Leaderboards and DLC visually, then click Generate Code for a type-safe SteamGame.gd wrapper and the AutoLoad that initialises it
• 🖥️ App, User and Utilities: App ID, DLC enumeration, install and beta info, launch parameters, local identity, Steam Deck detection
• 📡 Remote Play and Timeline: Session events, guest invite links, game phase, event markers and state tooltips
• 🔎 Matchmaking Servers: Server list requests, ping, player and rules queries
• 📚 Knowledge Base: More than API reference. Guides and articles cover every relevant feature of Steam, not just the SDK.
• 💬 Live Discord Support: Direct help from the Heathen team and a community of thousands of fellow developers.

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

Built for more than one engine

We have supported Steamworks across multiple engines for over a decade. This Foundation uses the same data shape as our Unity tools, written natively for Godot, so a team that works in both engines, or moves between them, keeps one way of thinking about Steam. The server configuration file, for example, uses the same keys and format in Unity and Godot, so one file can describe a server in either engine.

Requirements

• Godot 4.7 or compatible
• A registered Steamworks developer account
• Pre-built binaries for Windows, macOS and Linux (Debug and Release) are included, together with Valve's redistributable libraries. The Steamworks SDK is only needed if you want to build from source (SDK 1.64, not redistributed here), and a C++ build environment is only needed for that.
• Heathen Toolbox, which manages the Game Framework dependency for you. If either is missing, enabling this plugin walks you through fetching them automatically.

Toolkit for Steamworks extends Foundation with the high-level layer: session admission (whitelist and ticket validation), lobby managers, game server browsing, and a complete networked Demo Game. It is available through our Direct Code Access and installs through the Heathen Toolbox.
