GGPO is a C++ SDK that implements rollback networking, using input prediction and speculative execution to give online multiplayer games the feel of zero-latency play. It ships as a library with documentation and a sample Vector War application for integrating rollback into new or existing games.

Use cases

• add rollback netcode to a fighting game
• make online multiplayer feel like offline play
• implement input prediction and rollback for a real-time game
• synchronize game state across two or more clients with low latency
• learn how rollback networking works
• replace input-delay networking with rollback in an existing game

When to choose

• you are building a 2-4 player real-time game (especially fighting games) that needs responsive online play
• you want the industry-standard rollback SDK proven in shipped games
• you develop on Windows with Visual Studio and CMake

When to avoid

• you need turn-based or non-real-time multiplayer
• your game cannot be made deterministic or rewound (e.g., heavy physics or non-deterministic simulation)
• you require first-class Linux/macOS build support today
• you need a maintained project with active development
