Photon Realtime suits multiplayer game developers who need matchmaking, room-based play, and cloud-hosted networking across platforms. Its free development plan is limited to 20 concurrent users, while paid plans address higher usage.
Riptide suits developers building multiplayer games in Unity or other .NET environments. It is not suitable for browser-based games and true peer-to-peer use requires source changes.
