Yes, at OSM we’re editing a shared public map database.
Depending on your specific needs for map editing, uMap might be worth a look: https://umap.openstreetmap.fr/de/
It’s limited in the available cartographic tools (mostly drawing on top of an existing map), but it’s easy to use!
If that’s not sufficient for your use case, I wholeheartedly support n76’s suggestions. The software we’re using to run and edit OpenStreetMap is open source, so they can be used for your private data, too.
