Dolt is a SQL database with Git-style versioning. DoltHub is a place on the internet to share Dolt databases. Everyone has horror stories about a database broken by a bad query. A single mistake breaks your application for hours, days, or even months. Dolt solves this problem with a special type of replica you add to an existing MySQL deployment. No migration is required. You get an audit log of every cell, time travel, and branch for development on a replica. No risk to production.
