yojimbo is a C++ network library for client/server multiplayer games, designed around the needs of competitive games like first-person shooters. It provides encrypted UDP transport, connect-token authentication, reliable and unreliable messaging, and per-connection network statistics.

Use cases

• add client/server networking to a C++ game engine
• implement encrypted UDP transport for a multiplayer shooter
• send reliable-ordered and unreliable messages between game clients and server
• authenticate game clients with cryptographically secure connect tokens
• measure latency, jitter, and packet loss per connection
• fragment and reassemble large data blocks over UDP

When to choose

• your game engine is written in C++ and needs client/server networking
• you are building a competitive multiplayer game with roughly 100 players or fewer per server
• you want production-ready encrypted, authenticated UDP with reliability built in

When to avoid

• you need massively multiplayer servers with more than ~100 players per server
• you need multi-threaded networking (yojimbo is single-threaded)
• your game is peer-to-peer rather than client/server
