Infrastructure for
Galaxy-scale real-time shared environments where players and AI agents can all co-exist in a single living universe.
In Plain English
The virtual worlds science fiction has been imagining for decades are now possible.
Goodbye to picking a server or waiting in queues. Welcome to vast worlds you can truly explore with your friends.
Toss out the rulebook
CK Spatial Fabric is a horizontally scalable spatial router in software. Unlimited concurrent connections. One coherent environment.
This means Ready Player One's OASIS — one continuous virtual universe — is now technically possible.
One World. No Ceiling.
Every connection. Same world. Same state. Same time. No fragmentation, no hidden instances, no splits needed.
No number to plan around. No cap to engineer your way under. The architecture simply doesn't need one.
Worlds that exist continuously, remember everything, and never reset. One living environment — always on, always shared.
Every attendee in the same space at the same moment. No instances, no overflow rooms, no second-class experience.
Clusters scale horizontally on demand. Pay for what you use. No pre-provisioning, no capacity gambling, no surprises.
Addressable space larger than the observable universe. Build at any scale — the environment won't be the reason you stop.
Who This Is For
One shared environment for existing games, new worlds, and intelligent agent populations.
Bring an existing multiplayer game onto CK Spatial Fabric, one continuous shared environment beyond the limits of conventional replication, sharding, and instancing.
Explore Games → Indie Developers & Growing StudiosCreate and launch massive shared worlds without managing servers, shards, instances, or custom infrastructure. Build the world, not the backend.
Explore Games → AI Labs & Agent TeamsTrain and evaluate agent populations inside a persistent, real-time world, learning from real player behavior no simulation can fake.

Start in the browser, bring your own engine in portable C++, or go native in Unreal. Every SDK talks to the same shared world.
CrowdyJS wraps the Management and Game APIs behind a single typed client with shared auth. Ship a shared world straight from a web app — no engine required.
CrowdyJS SDKCrowdyCPP is a portable, high-performance C++ SDK that brings any non-Unreal engine or custom client onto CK Spatial Fabric — the same Management, Game, and Replication APIs, wrapped in typed C++.
CrowdyCPP SDKThe Unreal SDK spans all three layers — Management, Game, and Replication — so you can bring an existing engine project into CK Spatial Fabric or start a new one at native performance.
