Browser-Based 3D Modeling App (Hard-Surface Focus)

A web-based 3D modeling tool designed for hard-surface modeling workflows, similar to Blender but accessible from any device via browser. Users can edit, layout objects, apply nondestructive booleans, export OBJ files, and work on touch-friendly devices. Target: 3D hobbyists, designers, and professionals who want portable modeling without desktop software.

WebGL and WebGPU maturation has made serious browser-based 3D tooling genuinely viable for the first time, and the iPad Pro market alone represents a meaningful slice of professionals who want portable CAD-adjacent workflows without lugging a workstation. The closest competitor is Spline, though it targets motion/UI designers rather than hard-surface modeling, leaving a real gap for boolean-heavy, mesh-focused workflows. The $2k–$10k/mo band is realistic only as a niche subscription play — hard-surface hobbyists are notoriously price-sensitive, so revenue depends on landing prosumer and light professional users willing to pay $15–30/month rather than defaulting to free Blender. The single most likely failure mode is performance: non-destructive boolean operations on complex meshes are computationally brutal, and if the browser experience noticeably lags Blender on even mid-complexity models, users will tolerate the desktop install instead.
