Dolt is an open-source SQL database with Git-style version control built into the data layer. It behaves like a MySQL-compatible relational database while adding concepts such as commits, branches, diffs, merges, and history so teams can version and collaborate on database contents in a way similar to source code.

Users can query Dolt with SQL, connect standard MySQL clients, and use version-control operations to inspect or modify data history. The project also supports collaborative workflows around datasets, including branching for isolated changes, merging competing updates, and tracking exactly how rows changed over time.

Dolt is particularly useful for data applications where auditability, reproducibility, collaboration, or experimentation matters. It can serve as a normal application database while giving developers and data teams a much richer history and change-management model than conventional relational databases provide.
