About Toolkit for Steamworks 2026 – Unity Editor Tool & Plugin

Unity Steamworks Integration Toolkit

Toolkit for Steamworks 2026 provides Steamworks integration for Unity with systems covering achievements, stats and leaderboards, Steam Cloud, friends and social features, matchmaking, Steam Input, inventory, Workshop, Rich Presence, Remote Play, and Steam Game Server functionality. It provides both code-free tools and full C# access, while its Steamworks foundation is installed through the toolkit's dependency management.

Steamworks Features

The toolkit provides coverage across Steamworks systems including App Tools, Authentication, Clans / Groups Tools, Debugging Tools, DLC Management, Friends Tools, Steam Input, Inventory Management, Microtransactions & In-App Purchases, Crafting System, Player Trading & Economy, Leaderboards, Multiplayer, Lobby & Matchmaking, Steam Game Server, Steam Overlay, Parties, Remote Play, Remote Storage, Rich Presence, Screenshots, Stats & Achievements, User Tools, User-Generated Content, Utilities, and Voice Chat Integration.

Core Integration Systems

• Achievement System: Unlock, lock, and track achievement progress.
• Stats & Leaderboards: Work with integer and float stats plus global, friends, and weekly leaderboards.
• Cloud Storage: Read, write, and share save files through Steam Cloud.
• Friends & Social: Provides avatars, Rich Presence, overlay, and authentication sessions.
• Matchmaking: Create, join, and manage public, private, and friends-only Steam lobbies.
• Steam Input: Supports action sets, layers, and mapped actions.
• Inventory & Workshop: Provides item management, grants, exchange, UGC upload, and subscription functionality.

Steam Client and Listen Servers

The toolkit supports running a Steam Game Server in the same process as the Steam Client. A listen server can be listed on the Steam Server Browser without requiring a separate dedicated server build.

Its networking support can work with HLAPI solutions such as FishNet, Mirror, and MLAPI/NetCode for GameObjects.

Project Workflow

Steam App Settings allow achievements, stats, and leaderboards to be defined from Unity's Project Settings and then exposed through a generated wrapper. The toolkit also provides production-ready prefabs and sample scenes, while supporting both DOTS and traditional GameObject projects.

The Steam integration is built on the Heathen Game Framework, where Steam initializes as a Subsystem. An in-editor Build Guard warns about stale configuration before shipping.

Dependencies

The toolkit explicitly identifies several dependencies and supporting components. Heathen Toolbox provides version control and dependency management and can install missing components. Steamworks.NET and Foundation for Steamworks are free, open-source components that the Toolbox can install and update when missing. Heathen Game Framework provides the general framework and Subsystem architecture used by Steamworks.

Platform and Pipeline Support

Supported platforms and operating systems are Windows, Linux, and macOS. The render-pipeline compatibility entry for Unity 6000.0.71f1 marks Built-in, URP, and HDRP as Compatible.

The technical details also state that the toolkit is not impacted by the choice of rendering pipeline or InputSystem and works with them all.

Use Cases

• Steam games requiring achievements, statistics, leaderboards, Cloud Saves, or Rich Presence.
• Multiplayer projects using Steam lobbies, matchmaking, Steam Game Server functionality, or listen servers.
• Games requiring Steam Input, Workshop, inventory, trading, or user-generated content systems.
• Unity projects targeting Windows, Linux, or macOS with Steamworks functionality integrated into their gameplay systems.
