# TenIO `TenIO` is an open-source project to create multiplayer online games that includes a java NIO (Non-blocking I/O) based server specifically designed for multiplayer games, which supports UDP, TCP, Websocket, HTTP transports, and available simple client projects for quick development. ## Features - Scalable, distributed design - Easy-to-use, OOP design - Based on standard Java development, ensuring cross-platform support - Simple event handlers implementation - Simple physic simulator and debugger - Have simple existing game clients for rapid development ## Showcases | [
