Adminer
Adminer is a lightweight, open-source database management tool written in PHP that allows users to manage databases through a web interface. It supports a wide range of database systems, including MySQL, PostgreSQL, SQLite, and Oracle, enabling tasks like creating tables, running queries, and importing/exporting data. Unlike many alternatives, it is a single-file application, making it easy to deploy and use.
Developers should use Adminer when they need a simple, portable, and efficient tool for database administration without the overhead of heavier solutions like phpMyAdmin. It is ideal for quick database management tasks in development environments, debugging, or when working with multiple database types from a unified interface. Its minimal footprint also makes it suitable for resource-constrained servers or as a backup tool.
