I made https://konfig.xyz/ after making about 6500 images for a product configurator. Instead of using images, we use 3d models. Initially quite simple and for use with relatively flat scenes (ie - no tree like structure for options / scenes) but grown over time to sort of support those too. The main use case are fixed-in-size products that can be customize-able. So colours and materials, but also swapping one object for another, or turning one on or off (imagine rims on a car, or a bow thruster on a boat). We tried saas’in it completely, but the onboarding is proving to be quite hands-on. So we’ve partnered with a 3d firm that does the 3d work so we can focus ok building software
