HeidiSQL Overview

HeidiSQL is a free, open-source database client for Windows that connects to MySQL, MariaDB, PostgreSQL, Microsoft SQL Server, and SQLite. It provides a fast, lightweight interface for everyday database work: browsing and editing data in a grid, running and saving SQL queries, designing tables and views, exporting data and structure, and comparing or synchronizing databases. It is popular with web developers — it is commonly bundled with XAMPP-style stacks — for its speed and low resource use. A bulk table editor, a query profiler, and one-click export to SQL, CSV, HTML, or Excel cover everyday tasks, and you can manage users and privileges visually. The offline installer (and a portable build) installs without a network connection, though it connects to database servers when run. This page points to the genuine HeidiSQL source from Heidisql, not a third-party host.
