Dolt is a neat project, but it's tightly coupled to MySQL. Kart supports MySQL as a working-copy format but MySQL has some limitations around geometry support that make it unsuitable for most GIS usage - see our docs for more info: https://docs.kartproject.org/en/latest/pages/wc_types/mysql_...

Kart works with GIS working copies that are more familiar to GIS people - e.g. GeoPackage, Postgres/PostGIS & MSSQL databases. Differenet users can use different working copies, and still collaborate together too.
