3D scenes
Meshes, materials, lights and shadows on Babylon.js. Import .glb and .fbx by dropping them in, with their clips and textures discovered for you.
● Runs in the browser — nothing to install
Make games in 3D and 2D, in one editor.
A full engine in a browser tab: scene, physics, animation, particles, terrain and UI, driven by a visual node graph or by real code. Press Play. Export to the web, the desktop, or a phone.
No install. No credit card. Your first game exports free.

Everything in one place
A whole engine, not a toy
Every part below is in the editor today — no plugins to find, no second tool to learn, and nothing that only works in the demo.
2D, properly
Sprites, sheets, tilemaps imported from Tiled, and a paint editor. Flat projects get flat habits: front view, orthographic camera, bodies held in their plane.
Node graphs
96 nodes across events, flow, maths, transforms, physics, UI, audio and AI. Behaviour you can read across a room, and undo one step at a time.
Scripts
JavaScript in a Monaco editor that autocompletes against the engine's own declarations. Scripts and graphs call the same services, so an object can carry both.
Physics
Arcade collision for predictable platformers, or Havok for real rigid bodies and joints — hinge, ball, slider, spring. Same nodes either way.
Animation
A timeline with bezier curves and draggable handles, clips that cross-fade, and animation events that fire footsteps and hit frames on the exact frame.
Particles
Fire, smoke, sparks, magic, water, leaves and bursts as presets, tuned by eye while they run — and fired from a graph when something happens.
Audio
3D sound attached to objects with real falloff, a listener that rides the camera, and an audio editor for trimming what you import.
UI canvas
Menus, HUDs and score counters laid out on a visual stage that scales to any screen, with one-click bindings to the variables behind them.
Terrain & sky
Sculpt brushes, multi-layer texture painting, a scattering sky with a time-of-day control that moves the sun, the light and the god rays together.
Split screen
Up to four players on one screen. Objects have owners, so one graph copied onto two characters is already a two-player game.
Prefabs & scenes
Save a tree of objects, place it anywhere, and push a change to every instance. Multiple scenes, with objects that survive the switch.
A look inside
Real screenshots, taken from a running editor
Every picture here is captured automatically from the engine itself, so it cannot go stale.
A voxel world, its blocks, and the character that walks it
2D is the same editor, told to think flat
Behaviour as a graph — events, flow, and everything the engine can do
Or as code, against the same engine the nodes call
Particles, tuned by eye while they run
A timeline with real curves, and handles you can drag
The HUD, laid out on a stage that scales to any screen
A rigged character, cross-faded clips, a camera on a boom
An imported track, checkpoints, three timed laps
First person, a torch, and lighting that carries the mood
Fourteen finished games to start from, or take apart
Generators, the assistant and MCP — all on one account
Build it your way
A node graph, real code, or both on the same object
Drag out an event, wire it to what should happen, and watch it run. Or open the script editor and write it. They are two front ends onto one engine — the node that moves something and the line of code that moves something call the same method.
- 96 nodes: events, flow, maths, transforms, physics, UI, audio, tweens, AI
- Monaco editor with autocomplete built from the engine's own source
- Every change is one undo step, whichever way you made it
- Variables and messages are shared between graphs and scripts
3D and 2D
One editor that knows which kind of game you are making
2D is not a second engine bolted on. A sprite is ordinary geometry, so hierarchy, prefabs, colliders, outlines and physics worked on it the day it existed. Tell the project it is flat and the editor changes its habits to match.
- Tilemaps from Tiled, drawn as one mesh per layer and painted in the editor
- Sprite sheets cut once, named, and played by name — Aseprite exports read directly
- Front view, orthographic camera, drops that land on the plane
- Shapes clicked out in the viewport, and a paint editor for the one pixel that is wrong
Make the things you need
Assets and help, without leaving the editor
3D from a picture
Hand it a photo or a drawing and get a textured model back, downloaded straight into the project's folder. Paid for in credits, with the provider key on our server and never in your editor.
Images and music
Generate textures, sprites and backgrounds, or a piece of music for a level, and have them land in the project as assets you can use immediately.
An assistant that builds
Ask for a mechanic and it makes it — objects, components, graphs and scripts — by calling the same commands you do. A whole answer lands as one change, so one Ctrl+Z takes it all back.
MCP server
Claude, or anything that speaks the Model Context Protocol, can build in your running editor through the same tools. Each call is one undoable change, and you watch them arrive.
Asset explorer
Folders, previews, bulk edits, FBX import with a real converter on the desktop, audio trimming, and materials shared between any number of meshes.
Device preview
Frame the viewport to a phone or a tablet, turn it on its side, and force the on-screen thumbsticks in — so you find out how it feels before you build it.
Particles & animation
Tools that show you the answer while you change it
The particle editor runs the effect as you tune it. The timeline draws the real evaluator's curve, not a picture of one. Both are ordinary edits — Ctrl+Z works inside them like everywhere else.
Start from something that works
Fourteen finished games, open to the last node
Templates are ordinary projects: open their graphs, change anything, save it as yours. They are also how the engine tests itself — every one of them is opened and played on every change we make.
2D Platformer
A whole side-scrolling level: run, jump, collect, and something that walks at you.
Third Person
A rigged character with cross-faded clips and an orbiting camera.
GBX Craft
A block world with character select and a soundtrack.
Kart Circuit
Three timed laps around an imported track, checkpoint by checkpoint.
Horror FPS
A dark building, a torch, and a battery that is running out.
Split-screen Co-op
Two players, two cameras, one keyboard — or a gamepad each.
Ship it
Six ways out of the editor
One game, six destinations. The runtime travels with it, and nothing points back at us.
Web (HTML5)
A folder any static host will serve — itch.io, Netlify, GitHub Pages, your own server.
Publish online
One click and your game is on the web at a link you can send, hosted by us.
Windows
An app with its own window, built from the project the editor writes for you.
macOS
The same, as a .dmg, built and signed on a Mac.
Linux
An AppImage that runs on any distribution without installing anything.
Android & iOS
A Capacitor project, ready for Android Studio or Xcode and the stores behind them.
Two ways to run it
In the browser, or installed on your machine
The same editor either way, and the same account. The desktop build adds the things a browser will not do: projects saved straight to disk, native file dialogs, a real FBX converter, and the MCP server.
Run in the browser
Nothing to install. Open a tab and the editor is there, on any machine you sign in on.
Open the editor Chrome, Edge, Firefox or SafariWindows
An installer that puts GBX Engine in your Start menu, with .gbxproj files on disk.
Download for Windows Checking for a build…macOS
A disk image with the editor inside, for Apple silicon and Intel.
Download for macOS Checking for a build…Linux
An AppImage: make it executable, run it, and nothing else is installed.
Download for Linux Checking for a build…The desktop builds are unsigned for now, so Windows SmartScreen and macOS Gatekeeper will warn on the first run. On Windows choose More info → Run anyway; on macOS right-click the app and choose Open.
