There are many GUI tools that work with MariaDB, such as Webyog/SQLyog, HeidiSQL, dbForge Studio for MySQL, and of course, MySQL Workbench.

We know some tools have received requests and/or are working to add support for MariaDB and Aria-specific features (SQLyog, for example). Until your preferred GUI tool supports MariaDB and Aria-specific features directly, most of the tools provide a mechanism for editing and executing custom SQL code.
