Free, open-source, single-file PHP database management tool supporting MySQL, PostgreSQL, SQLite, MS SQL, Oracle, and more.
Adminer is a free, open-source database management tool created by developer Jakub Vrána and first released in 2007 as a lightweight alternative to phpMyAdmin. Its defining feature is that the entire application ships as a single PHP file.
Because it requires no separate install process beyond uploading that file to a PHP-enabled server, Adminer is especially portable and easy to deploy on shared hosting or alongside other web applications.
Adminer supports browsing and editing table structures and data, running raw SQL commands, exporting databases, and managing indexes, foreign keys, views, stored procedures, triggers, and user/rights management.
It natively supports MySQL, MariaDB, PostgreSQL, SQLite, MS SQL, Oracle, and CockroachDB, with plugin-based support for additional systems like MongoDB, Redis, Elasticsearch, and Firebird.
Adminer runs on any server with PHP 5.3+ and sessions enabled. Community-maintained packages make it easy to deploy via Docker, Debian, WordPress, Drupal, and other platforms.
