MySQL vs MariaDB: Complete Comparison Guide
Compare MySQL and MariaDB on functionality, licensing, storage engines, and compatibility. Discover which relational database is the best fit for your project.
MySQL and MariaDB are closely related but increasingly diverging. MySQL remains the most popular choice with the largest ecosystem and Oracle support, but corporate control concerns some open-source advocates. MariaDB offers extra features like Aria and ColumnStore storage engines, better encryption in the community edition, and no vendor lock-in. For most web applications, they are interchangeable. The choice depends on whether you value the broader MySQL ecosystem or MariaDB's open-source philosophy.
MySQL
The most popular open-source relational database in the world, owned by Oracle. MySQL provides reliable ACID transactions via InnoDB, extensive replication options, and a massive ecosystem of tools and hosting providers. It is the standard database for millions of web applications, from WordPress to large enterprise systems.
MariaDB
A community-driven fork of MySQL, created by MySQL's original founder Monty Widenius. MariaDB offers full MySQL compatibility plus additional storage engines (Aria, ColumnStore, Spider), improved performance optimizations, and a strong focus on open-source freedom without corporate control.
What are the key differences between MySQL and MariaDB?
| Feature | MySQL | MariaDB |
|---|---|---|
| Ownership | Oracle Corporation — dual-licensed (GPL + commercial) | MariaDB Foundation — fully open-source (GPL v2) |
| Storage engines | InnoDB (default), MyISAM, NDB Cluster | InnoDB, Aria, ColumnStore, Spider, MyRocks, and more |
| Compatibility | Reference implementation — all tools work with MySQL | Drop-in replacement for MySQL 5.7; versions diverge afterwards |
| Performance | Solid performance with InnoDB — focus on stability | Thread pool, query optimizer improvements, and parallel replication |
| JSON support | Native JSON type with functions since MySQL 5.7 | JSON as alias for LONGTEXT — less native support |
| Encryption | Tablespace encryption in Enterprise Edition | Data-at-rest encryption available in the community edition for free |

Which option does MG Software recommend?
At MG Software, we recommend PostgreSQL over both MySQL and MariaDB for most new projects due to its superior feature set, extensions, and scalability. When a client specifically needs a MySQL-compatible database, we recommend MariaDB for its open-source license and additional features like data-at-rest encryption. We recommend MySQL when specific compatibility with MySQL-only features or Oracle support is required.
