Start here
Installing, setting up each platform, your first scene, and the editor. Read in order it takes you from nothing to a cube you can orbit.
Documentation
Orblit is a Dart-first 3D game engine: game logic and interface in Flutter, an entity-component core in C++, and Filament doing the rendering. These pages are the whole of what is written down about it.
It is pre-alpha, so take platform support seriously before you plan around anything here.
Start where you are
Section titled “Start where you are”I want to know what this isWhat Orblit does that another engine does not, in about five minutes.
I want a window on screenInstalling the packages, then setting up whichever platform you are on.
I want to see it runningThe gallery, the viewport app, the headless simulation and a block game to walk around in.
I want to understand the shape of itHow Flutter, Dart and the C++ core divide the work, and why the seams are where they are.
What is here
Section titled “What is here”Concepts
The four ideas the rest of the documentation assumes: how it fits together, stating a scene, entities and components, and sampled time.
Guides
One page per thing you might go looking for by name — models, materials, textures, lighting, cameras, splats, interfaces, multiplayer, 2D.
Reference
The packages and what each one is for, what the renderer supports, and what has actually been seen running on each platform.
For language models
Section titled “For language models”Every page here is also plain Markdown at its own address with .md on the
end, so /docs/start/installing/ is also
/docs/start/installing.md. There is an index of
the lot at /llms.txt, and the whole site as one file at
/llms-full.txt. Working with AI
assistants covers pointing a coding assistant at
them, and the Claude Code skill that ships with the engine.
