Description
Nebula Forge is a free WebGL browser tool from NebulaKit for exploring procedural space backgrounds. Adjust the palette, seed, density, stars and exposure, then save a PNG of the current preview. Rendering runs locally on the device; the export uses the adaptive preview resolution, not a guaranteed 4K size. The images are generated by a procedural volumetric algorithm. The code and interface text were developed with AI assistance. Exported images may be used in personal and commercial projects; standalone asset-pack resale is excluded. The browser generator is free. Its page also links to separate optional paid Blender and motion products.
