Use Epic Online Services in Unreal Engine! With support for authentication, avatars, friends, sessions, parties, Voice Chat, presence, stats, achievements, leaderboards, Player Data Storage, Title Storage, peer-to-peer networking, Anti-Cheat and network authentication, this plugin has what you need to build games on top of EOS.

It supports neat features, like showing a unified friends list of friends from both the native platform and Epic. It allows you to seamlessly invite friends to parties from other platforms like Steam, and it fully supports play-in-editor so you don't need to set up multiple machines to do your testing on.

Authentication is handled for you. You don't need to deal with account linking or creation, and you don't need to build user interfaces to support the Epic Online Services login flow. Just call AutoLogin and you're done.

Looking for team matchmaking with any layout (4v4, 1v2v3, etc.) and no matchmaking servers required? Take a look at our new Matchmaking plugin!

If you're a developer earning less than $30k USD/yr, a Free Edition is available. Check the website to see if the Free Edition is right for you.

If you need blueprint support, check out Online Subsystem Blueprints. EOS Online Subsystem only provides C++ support by default, so if you need blueprint support, you will need to buy OSB as an additional purchase.
