MariaDB is a backward compatible, drop-in replacement branch of the MySQL® Database Server. It includes all major open source storage engines, including the Maria storage engine.
You can find the MariaDB code on Launchpad, and download binaries here.
MariaDB is community developed in collaboration with Monty Program. Our ambition is to make MariaDB the best open and free branch of MySQL Database Server for the end user, developer and partner communities.
