Photon Server

What Photon Server is
Photon Server is an on-premises real-time socket server and multiplayer framework for teams building and hosting game backends on machines they choose. Its C# server applications can be used as supplied or customized, connecting players and exchanging data in shared sessions. Core transport includes reliable UDP, binary TCP, HTTP, WebSocket and Secure WebSocket, with a client-server network model and matchmaking. The C# framework maps RPC calls to operation instances and uses fibers for message-passing threading. Developers can debug in Visual Studio; Redgate and JetBrains tools are also listed. Photon Server has no persistence layer, although SQL and NoSQL databases usable through .NET on Windows are documented. LoadBalancing (MyCloud) works with Photon Cloud and is recommended for PUN, Photon Voice and Photon Realtime clients. Authentication providers include Epic EOS, Facebook, Oculus, Steam and VIVEPORT. Pricing starts at $500/mo; no free plan is listed.
Who it suits
It suits teams wanting to host and configure their own multiplayer backend with C# and Windows-based database options. It is intended for on-premises deployments requiring supported real-time protocols and matchmaking.
What it does well
- On-premises hosting on chosen machines
