AppSynergy uses MariaDB as its SQL engine (with various enhancements added, like AppSynergy's Federated features). You can see which core version of MariaDB your account is currently running on via Help > About....
You can allow other applications to access your database via ODBC/JDBC, AppSynergy's REST API, or compatible command line tools. You grant access by creating an API Key. Each API key is assigned to a Security Role which determines which operations are permitted.
See Tools > API Keys... to create an API key. Each API key is assigned to a Security Role which determines which operations are permitted.
The AppSynergy REST API allows you to make RESTful calls to your database. See the AppSynergy REST API documentation for details.
If you opt for an AppSynergy plan with a dedicated database server you will have full root access to your private database server at all times.
The AppSynergy database is fully compatible with third-party tools that work with MariaDB, ODBC and JDBC. You can download the latest compatible drivers by clicking below.
