Photon Server API
Photon Server is an on-premises real-time socket server and cross-platform multiplayer game development framework that is extremely fast and very easy to use.
Client SDKs are available for all major platforms.
Use the multiplayer API from Photon Server to join many players together in a shared game session and transfer data and messages synchronously, in real-time, between connected players across platforms. All client SDKs can interact with each other, no matter if iOS, Android, Web or standalone.
Happy coding!
