DB Explorer

DB Explorer is a free, cross‑platform tool that lets developers, database administrators, and analysts connect to a variety of database systems, write and run SQL statements, and explore schema structures through a graphical interface. It supports PostgreSQL, MySQL, MariaDB, SQL Server, Oracle, SQLite, Amazon DynamoDB and any JDBC‑compatible database, offering features such as pagination, data export, and connection‑health monitoring.

The application includes a multi‑theme GUI with color‑coded status messages, keyboard shortcuts, and confirmation dialogs to streamline the user experience. It visualizes table relationships, provides lazy loading, configurable limits, connection pooling, and memory management to maintain performance and reliability across large datasets.

A distinctive aspect of DB Explorer is its AI‑driven SQL generator, which can produce queries based on natural‑language prompts and the current context. It also offers health dashboards, statistics views, configuration management, and the ability to export schema diagrams as PNG images or Mermaid markup. The project is released under Apache 2.0, GPLv3, and LGPLv3 licenses.
