Adminer
Adminer manages databases from a single PHP file and supports MySQL, MariaDB, PostgreSQL, SQLite, MS SQL, Oracle, Elasticsearch, MongoDB, and other systems. It is for people who manage databases on one or more of these platforms. The single-file format gives users one PHP file for database management across the named systems. This includes widely used SQL databases, as well as Elasticsearch and MongoDB. Adminer can serve users who work with one database system or several supported systems. Adminer is limited to database management rather than broader software, server, or application administration. Its single-file PHP format may also be a limitation for users who do not want to use a PHP file. The program does not have a specific paid replacement among the available facts, so no direct commercial comparison can be made. Support extends beyond the named databases, but those other systems are not listed.
