Overview
Photon Fusion is a state-transfer netcode SDK for multiplayer games made with Unity, Unreal, and Godot. Its tick-based simulation supports client-side prediction and snapshot interpolation, while lag compensation addresses the delay between a client firing and the server registering a possible hit. Developers can choose full-consistency replication or eventual-consistency replication, which uses less bandwidth per object. Available network topologies include dedicated server, client host, and shared authority. Engine availability has qualifications: the product page lists all three engines, while documentation marks Unreal as early access and says Godot early access is available by contacting Photon. Dedicated-server use is described as a headless Unity build and requires third-party server orchestration at additional cost. Free plans include a 100-CCU option and a development-only option for 20 concurrent users. A one-time 100-CCU plan costs 95.00 USD for 12 months; monthly plans include 125.00 USD for 500 CCU. Premium Cloud is billed at 0.50 USD per CCU per month, with a 1,000 USD monthly minimum. All plans include online documentation, samples, tutorials, video streams, and help with account, billing, and service-status issues.
Who it is for
