MariaDB is a community-developed fork of the MySQL relational database management system intended to remain free under the GNU GPL. It is notable for being led by the original developers of MySQL, who forked it due to concerns over its acquisition by Oracle. Contributors are required to share their copyright with the MariaDB Foundation.
MariaDB intends to maintain high compatibility with MySQL, ensuring a "drop-in" replacement capability with library binary equivalency and exact matching with MySQL APIs and commands. It includes the XtraDB storage engine for replacing InnoDB, as well as a new storage engine, Aria, that intends to be both a transactional and non-transactional engine perhaps even included in future versions of MySQL.
Its lead developer is Michael "Monty" Widenius, one of the founders of MySQL AB and the founder of Monty Program AB. On 16 January 2008, MySQL AB announced that it had agreed to be acquired by Sun Microsystems for approximately $1 billion. The acquisition completed on 26 February 2008. MariaDB is named after Monty's younger daughter Maria, similar to how MySQL is named after his other daughter My.
MariaDB version numbers follow the MySQL's numbering scheme up to version 5.5. Thus, MariaDB 5.5 offers all of the MySQL 5.5 features. There exists a gap in MySQL versions between 5.1 and 5.5, while MariaDB issued 5.2 and 5.3 point releases.
After the 5.5 version, MariaDB developers decided to start a branch numbered 10, as an attempt to make it clear that MariaDB 10.0 will not import all features from MySQL 5.6; however, they might be imported in future versions. Since specific new features have been developed in MariaDB, the developers decided that a major version number change was necessary.

MariaDB's API and protocol are compatible with those used by MySQL, plus some features to support native non-blocking operations and progress reporting. This means that all connectors, libraries and applications which work with MySQL should also work on MariaDB—whether or not they support its native features. On this basis, Fedora developers replaced MySQL with MariaDB in Fedora 19, out of concerns that Oracle is making MySQL a more closed software project.
Tools known to work properly with MariaDB include:
- Database Workbench – a commercial software application for development and administration of multiple relational databases (including MySQL), with inter-operationality between different database systems
- DBEdit – a free administration application for MariaDB and other databases
- HeidiSQL – a free and open-source client for MySQL on Windows. It supports MariaDB specific features like virtual columns, and is included with the Windows MSI package of MariaDB beginning with the 5.2.7 release.
- Navicat – a series of proprietary database-management applications for Windows, Mac OS X, and Linux
- phpMyAdmin – a web-based database management application for MySQL
- SQLeo – a visual query builder that helps users to write or understand SQL queries
- SQLyog – a database management application on Windows and on Linux
The following web applications officially support MariaDB:
The following is a partial list of distributions which include MariaDB in their package repositories:
- BSD Distributions
- Linux Distributions
- Alpine Linux
- Arch Linux - features MariaDB 10.0, replacing MySQL as a default
- ALT Linux
- The Chakra Project - features the latest MariaDB 5.5 release, replacing MySQL as a default
- Fedora - MariaDB 5.5 became the default relational database from Fedora 19, and MariaDB 10.0 from Fedora 21.
- Gentoo Linux
- GNU/Linux KDu - features the latest MariaDB 5.5 release, replacing MySQL as a default since version GNU/Linux KDu 2.0 Final
- Mageia - features the latest MariaDB 10.0 release, and has replaced MySQL as a default
- Manjaro Linux - MariaDB 10.0 is available in stable.
- openSUSE - MariaDB 5.5 became the default relational database in openSUSE 12.3, and MariaDB 10.0 the default since 13.2
- Oracle Linux - starting in version 7 (this is notable because Oracle publishes MySQL, but their binary compatibility promise requires defaulting to MariaDB, although MySQL is also available)
- Parabola GNU/Linux
- Red Hat Enterprise Linux - MariaDB 5.5 has been the default database since RHEL 7
- Slackware - has used MariaDB as default, replacing MySQL, since 14.1

In December 2012, Michael Widenius, David Axmark, and Allan Larsson announced the creation of a foundation that would oversee the development of MariaDB. In April 2013, the Foundation announced that it had appointed Simon Phipps as its Secretary and interim Chief Executive Officer, Rasmus Johansson as Chairman of the Board, and Andrew Katz, Jeremy Zawodny, and Michael Widenius as Board members. Noting that it wished to create a governance model similar to that used by the Eclipse Foundation, the Board appointed the Eclipse Foundation's Executive Director Mike Milinkovich as an advisor to lead the transition.
SkySQL Corporation Ab, a company formed by ex-MySQL executives and investors after Oracle bought MySQL, announced in April 2013 that they were merging their company with Monty Program Ab, and joining the MariaDB Foundation. SkySQL's CEO Patrik Sallner would lead the new merged company, and Widenius was appointed as its CTO by the MariaDB Foundation.
On October 1, 2014, SkySQL Corporation Ab changed its name to MariaDB Corporation Ab to reflect its role as the main driving force behind the development of MariaDB server and the biggest support provider for it.
