Yeah I think you're right. It calls that out (in really tiny footer text) that it's leveraging ml-sharp.
It's pretty trivial to get running locally and generating the PLY files. Spark's a pretty good renderer for it after you've generated the gaussian splats.

This is just Apple's tool plus a splat viewing library? Perhaps disingenuous to call "our web app"
This is the heavy lifting: https://github.com/apple/ml-sharp
