Make room for discovery.
Generate terrain from recipes, sculpt the surface and explore lighting and materials. Export a heightfield or scene mesh.
Build a landscape. Shape an object. Bring a scene to life. Explore Aether’s terrain, modeling and game authoring tools in one workspace.
Free browser beta · no sign-in required · desktop browser recommended

Start in the browser and keep your project as a portable JSON file. The desktop build adds the native engine and exact CAD tools.
Generate terrain from recipes, sculpt the surface and explore lighting and materials. Export a heightfield or scene mesh.
Create mesh primitives and editable curves. Apply modifiers, tune materials and export GLB or OBJ assets. Exact CAD lives in the desktop runtime.
Arrange objects, animate transforms and try a local logic preview. Native gameplay, packaged builds and the featured game examples run on desktop.
Real captures from working development builds. Each image identifies its workflow so you can see what runs in the browser and on desktop.

Northwatch sample scene with terrain, architecture, water and vegetation.

A tube mesh follows an editable curve recipe, with radius and point controls.

An exact loft between circular sketches, hollowed with a shell feature.

Rounded mounting plate with cylindrical mounting holes.

Native Vulkan launch-frame preview of the platformer sample, with collectible objectives and a game HUD.

Bronze material preset on the tube model in the shared renderer.
| Workflow | Web beta · available now | Desktop beta · Windows & Ubuntu |
|---|---|---|
| Scenes & terrain | Scene editor, terrain recipes and sculpt tools | Shared editor plus native terrain pipeline |
| 3D models | Mesh tools, curves, modifiers and materials | Mesh tools plus exact solid CAD |
| Animation & games | Transform timeline and local logic preview | Native gameplay and game packaging |
| Export | Project JSON, GLB, selected mesh OBJ, terrain heightfield | Additional CAD and fabrication exports |
| Project storage | This browser; export a JSON backup | Local files on your computer |
Beta software is still evolving. Browser scene export does not include water, atmosphere or timeline animation. Exact CAD evaluation and native game builds are not part of the browser beta.
Yes. Open the workspace directly without signing in. Aether runs the shared editor in your browser; a desktop browser with WebGL enabled is recommended.
Save writes to this browser on this device. It does not upload your work to an account. Export project JSON regularly for a portable backup; clearing browser data can remove local projects.
Windows and Ubuntu Linux installers are available with a free account. Install the complete desktop beta, or try the web workspace without signing in. macOS is not yet available.
No. These are captures of Aether development builds and exported viewers. The showcase ledger labels full screenshots and viewport crops. Software rendering was used during capture; these images are not a performance benchmark.
Your next idea starts with an empty workspace.
J Simulation is now a standalone engineering preview with separate installers and study files.
