Web-native
No installs to start
The whole editor runs in a browser tab on Three.js & WebGL. Open a link and you're building — share a project as a portable .nforge file.
Browser-native 3D engine
Build 3D games. In your browser.
Feather Engine is a real-time 3D editor with physics, a blueprint-style visual scripting graph, and a built-in AI assistant — all running on the open web. No compilation. No plugins. Hit play and your game runs.

What is Feather Engine
A full game editor that lives on the web — scene, physics, logic and runtime in one tab.
Manage a scene hierarchy, attach mesh renderers and rigid bodies, wire gameplay with a node graph, then press play to run it in real time. It even packages into a native desktop app when you want real project folders on disk.
No compilation
Hit play, it runs
A real Rapier rigid-body world steps live as you press Play. Your visual-scripting graph ticks every frame with keyboard input and events — instant feedback, zero build step.
AI-assisted
An agent in the editor
A built-in AI assistant drives the engine through tools — spawn objects, wire nodes, set up physics. Describe what you want and watch the scene build itself.

Describe it — the agent builds it
An agentic assistant drives the editor with real tools. Bring your own OpenAI, Anthropic or Google key.
Physics
Rapier rigid bodies
Colliders, triggers, forces, layers.
// a complete engine, not a toy
Everything you'd expect from a native engine — in the browser
Feather Engine isn't a tech demo. It ships the systems real games need — controllers, physics, animation, cinematics, destruction and more — all editable live and drivable from the visual graph or the AI assistant.
Character Controller
First/third-person movement, sprint, crouch, jump feel, melee, dodge, swim & climb.
Vehicle Physics
Arcade driving with suspension, steering, wheels, headlights and engine audio.
Procedural Terrain
Perlin-noise terrain, chunk streaming, sculpt & paint, layered materials, foliage.
Animator + Foot IK
State machines, parameters, 1D/2D blend spaces, cross-fades, procedural foot IK.
Ragdoll & Skeletons
Per-bone rigid bodies with joints, sockets, skeletal mesh reuse across rigs.
Particle Systems
Reusable emitters, shapes, gradients, blend modes, sprites and light emission.
Cinematics
Film-mode sequencer: spline camera paths, keyframes, DoF, color grading, slow-mo.
Material Node Editor
Procedural shader graphs — color, scalar, texture, mix, multiply, clamp.
UI & Minimap
Drag-drop widgets, variable bindings, diegetic in-world screens, GTA-style radar.
Fracture & Destruction
Shatter meshes into grid/chunk/shatter patterns on impact thresholds.
Projectiles & Combat
Spawn projectiles with spread, damage, knockback and area-blast detonation.
Save / Load
Slot-based persistence, project variables that survive scene loads.

Visual scripting
Wire gameplay logic, no code required
A blueprint-style graph connects events to actions across 100+ nodes — branch on input, spawn projectiles, drive the animator, query line-of-sight to the player, save the game. Every node ticks against the live runtime the instant you press play.

Your tools, your keys, your build
Feather Engine is open and unopinionated about your pipeline. Drive it by hand, by graph, or by AI — then export a real, portable game.
Bring your own AI key
Wire the editor's agent to OpenAI, Anthropic or Google. It drives 90+ tools — create objects, edit components, author graphs — and stays aware of your live scene.
Export anywhere
Ship a self-contained web folder that runs from any static host, or package a native desktop app for macOS, Windows and Linux via Tauri.
Open & inspectable
MIT licensed, built on React, Three.js, Rapier and React Flow. Projects are plain JSON — read them, diff them, script them.

Your assets, rendered live
This isn't a picture — it's a real Three.js scene running in your browser, the same renderer the engine uses. Spin the models that ship with Feather Engine's templates and see the lighting, bloom and reflections update live.
glTF / GLB import
Drag models straight into the scene — rigged meshes, materials and animations intact.
PBR materials
Metalness, roughness, emissive and normal maps, with live per-instance overrides.
Physics-ready
Attach colliders and rigid bodies so every asset reacts the moment you press play.
