## What it is
Steamworks.NET is a C# wrapper for Valve's Steamworks API, usable with Unity or any C#/.NET application. It provides a near 1:1 mapping to the native C++ API with 100% interface coverage, supporting Windows, macOS, and Linux.

## Use cases
- add Steam achievements and stats to a Unity game
- implement Steam leaderboards in a C# game
- set up Steam multiplayer matchmaking and lobbies
- authenticate Steam users and verify ownership
- sync save games with Steam Cloud
- use Steam P2P networking without port forwarding

## When to choose
- you're building a Unity or C# game that ships on Steam
- you want full Steamworks API coverage with a thin, faithful C# mapping
- you want to rely on Valve's own C++ documentation directly

## When to avoid
- you want idiomatic C# abstractions rather than a close-to-C++ API
- you're targeting platforms outside Windows/macOS/Linux
- you're not distributing through Steam

## Facets
- artifact type: library
- maturity: active
- function: sdk, auth, p2p, cryptography
- domain: gaming-tools, cross-platform
- platform: windows, game-engine, dotnet, cpp
- tags: steamworks, steam, unity, c-sharp, game-integration, achievements, leaderboards, matchmaking, steam-cloud, interop, game-development, macos, linux
