Features
Production-ready multiplayer networking for Unity. Everything you need to ship a networked game.
Available on the Unity Asset Store
GONet (free, v1.5) is available now on the Unity Asset Store. Get started with multiplayer networking today.
GONet Legendary (paid, v1.6+) is coming soon with Steam transport integration, fast iteration mode, cloud replay storage, ticket support, and more.
GONet Legendary launches as one paid tier. Optional advanced cloud usage tiers for AI-assisted analysis and esports-scale replay workflows may be introduced later.
Core Features in Detail
A comprehensive networking toolkit with no artificial limitations on the features that matter.
Auto-Magical Data Synchronization
Synchronize game state across the network with minimal configuration. GONet handles the complexity of keeping distributed state consistent.
Velocity-Augmented Sync
GONet's signature bandwidth optimization. Instead of sending full position values every frame, the system alternates between VALUE and VELOCITY packets. Clients extrapolate using the last-known velocity, dramatically reducing bandwidth for objects with predictable motion.
SoA + Burst Blending
Structure-of-Arrays layout with Unity Burst-compiled parallel jobs processes all networked objects in a single pass, achieving 85% CPU reduction vs per-object blending.
Async/Await RPCs
Modern RPC system with native async/await, server-side validation, and persistent RPCs for late-joiner support.
Event Bus System
A type-safe publish/subscribe system with hierarchical routing, persistent event replay for late-joiners, and object pooling for transient events.
Time Synchronization
Production-grade time sync using an NTP-style 4-timestamp protocol with Golden Sample filtering to resist bufferbloat and network jitter.
Host Migration & Failover
GONet LegendaryDistributed host architecture with automatic recovery. If the host disconnects or crashes, a new host will be elected and the session will continue seamlessly.
Transport Layer
Pluggable transport abstraction with production-ready implementations. NetcodeIO provides UDP with encryption and token-based authentication out of the box.
GONet Legendary: Steamworks P2P transport with Steam Datagram Relay for NAT traversal.
Congestion Management
Adaptive per-client congestion control that automatically adjusts sync rates and buffer sizes based on real-time network conditions.
Serialization & Compression
Efficient data serialization with multiple compression strategies, optimized for low-bandwidth multiplayer.
Code Generation
Zero-boilerplate networking through compile-time code generation. GONet generates companion classes that handle serialization, deserialization, and sync automatically.
Fast Iteration ModeGONet Legendary
Skip the code generation step when entering Play mode for near-instant iteration. Perfect for rapid gameplay prototyping without waiting for the full generation pipeline.
12-Channel Message Routing
A priority-based channel system that separates system-critical traffic from gameplay data, ensuring that connection management and time sync are never delayed by game state updates.
Spawning & Object Pooling
Network-aware instantiation with zero-latency spawning via GONetId batch pre-allocation and configurable limbo modes for edge cases.
GONet Legendary: Built-in adaptive object pooling with IGONetPoolResettable and automatic pool scaling.
Record & ReplayGONet Legendary
Capture full multiplayer sessions with zero gameplay impact. Play back with seeking, reverse, and speed control. Analyze with built-in anti-cheat, performance, and highlight detection.
Network & Platform
Broad protocol and platform support for any multiplayer architecture.
