Screenshot of in-game chat built with assets from the Unity SDK plugin

Ready for multiplayer console titles, viral mobile games, and everything in between, the Unity Chat SDK helps developers add in-game messaging that just works — whether you have 10 players online or 10 million.

This low-level client brings the power of the Stream Chat API into your existing Unity game engine environment. Start with the Unity In-Game Chat Tutorial, then customize features and UI complexity to match your genre and concept.

Along with the Unreal SDK, this v1.0 release makes Stream Chat more accessible to game developers and studios of all sizes, with reusable assets and components via an SDK plugin. Support for additional API features coming soon.
