Kepler-442 and Onshape both run fully in the browser, but Kepler-442 is AI-native — generating editable 3D from text, simulating automatically, and sourcing factories — while Onshape focuses on cloud-based collaborative parametric CAD.
Onshape pioneered serious browser-based, cloud-collaborative parametric CAD. Kepler-442 shares the no-install advantage but layers on AI generation, continuous physics testing, and a manufacturing marketplace, targeting founders who want to ship a product rather than master CAD.
| Capability | Kepler-442 | Onshape |
|---|---|---|
| Browser-based | Yes | Yes |
| AI text-to-3D | Native | No |
| Real-time collaboration | Yes | Yes (core strength) |
| Automatic simulation | Yes, on every save | Limited |
| Supplier marketplace | Built in | No |
| Target user | Founders & designers | Engineering teams |
Both are browser-based CAD platforms, but Kepler-442 is AI-native: it generates editable 3D geometry from text, runs automatic physics simulation, and includes a verified supplier marketplace, whereas Onshape centres on cloud-based collaborative parametric modeling.
