There is Cesium. But the thing you actually need is the actual maps. There are free maps (many of them based on OpenStreetMap), but the fidelity you know from Google Earth is usually not free. Also if you also want to self-host the actual maps you need a tile server for that and lots of disk space because these tiles take up a lot of it...

This looks cool as heck. I’ve got a few extra TBs and I only need my town, not like the whole east coast. I don’t mind throwing some dollars at this if it is able to keep me off Google. I really don’t like those guys lol
If you don't mind some learning curve, check out QGIS: https://qgis.org/ ...it can pull data in from many different sources and it's free :)
Loving all of these options. Thanks for this!
Not only can you create your own maps using QGIS, it also has plugins that lets you create webapps out of them that anyone in your network can access, without coding.
When I last played with this a decade or so ago, there were several map tiling solutions in the geosciences that are self hosted.
From memory, "World Wind" is a good search term, but there's others.
Thanks. I’ll check it out.

Not really selfhosted, but a decent open source app:
https://marble.kde.org/features.php
You probably can put it in a kasm workspace or noVNC docker container if you really want to selfhost it.
I don’t have to self host, I was just looking for an un-googled option which would allow me to save data and chart over periods of time.
