Adminer

Adminer is an open-source database management tool written in PHP. It is designed as a lightweight, portable alternative to phpMyAdmin. The software is distributed as a single PHP file that can be uploaded to a web server and run without requiring other dependencies.

Adminer was created by Jakub Vrana, originally under the name phpMinAdmin, and was later renamed to Adminer. It has since evolved to support multiple database systems and a range of administrative features.

The program supports several database management systems, including MySQL and MariaDB, PostgreSQL, SQLite, Microsoft SQL Server, and Oracle Database. It provides common database administration capabilities such as browsing and editing database objects, running SQL queries, importing and exporting data, creating and modifying tables and indexes, managing users and permissions, and viewing database statistics. It also offers a simple, clean user interface and multilingual support.

Adminer is designed to be embedded in a project or hosted on a server as a standalone tool. Since it is a single file, it can be deployed quickly and can connect to local or remote databases by supplying credentials. For security, administrators typically place Adminer behind access controls such as web server authentication or IP restrictions.

Adminer is released under the MIT license and is maintained with regular updates. The official source and downloads are hosted on adminer.org; there are also community-contributed plugins and translations.
