Epic Online Services vs Steamworks SDK
Side-by-side comparison of features, pricing, ratings, and alternatives.
Epic Online Services (EOS) provides a comprehensive set of cloud‑based tools that let developers add multiplayer, authentication, achievements, leaderboards, and more without building their own backend. The SDK integrates with popular engines like Unreal and Unity and works across consoles, PC, and mobile devices. EOS is free to use, scales automatically, and includes ready‑made services such as matchmaking, voice chat, and anti‑cheat, allowing studios to focus on gameplay while leveraging Epic's global infrastructure.
Steamworks SDK provides a comprehensive set of APIs, libraries, and documentation that let developers integrate Steam features such as achievements, leaderboards, matchmaking, and in‑app purchases directly into their games. It streamlines distribution, DRM, and community interaction, helping studios of any size bring their titles to the world's largest PC gaming platform. The SDK is continuously updated to match Steam client changes and includes sample code, testing tools, and extensive support resources. It works across major desktop operating systems and supports both native and engine‑based workflows, making it a go‑to solution for PC game development.
