Photon Engine

Photon Engine, developed by Exit Games, is a Hamburg-based game networking company that provides the most widely deployed real-time multiplayer networking SDK in the game development industry, supporting over 1.5 billion connected devices across thousands of published games. Photon's SDKs abstract the complexity of peer-to-peer and server-authoritative networking for Unity, Unreal Engine, JavaScript, iOS, and Android, enabling developers to add real-time multiplayer, game rooms, matchmaking, and state synchronization without building custom networking infrastructure. The Photon Cloud service manages server infrastructure globally across multiple regions with automatic scaling and low-latency routing, while Photon Server allows studios to self-host for complete control. Photon offers multiple specialized products including Photon Fusion and Photon Quantum for physics-synchronized competitive multiplayer, Photon Voice for in-game proximity chat, and Photon Realtime for general-purpose multiplayer. The free tier and transparent per-CCU pricing model has driven broad adoption among indie studios and major publishers alike; notable games built on Photon include Pokémon GO (Niantic), Angry Birds 2, and games from EA and Ubisoft studios. Founded in 2002, Photon competes with Mirror, Netcode for GameObjects, and Multiplay in the game networking infrastructure market.
