What it is

HeidiSQL is free desktop database client software for connecting to databases and editing their data and structures. It supports MariaDB, MySQL, MS SQL, PostgreSQL, SQLite, Interbase, Firebird, ProxySQL, and Redshift, with multiple connections in one window. Connections can use SSH tunnels or SSL settings. Users can create and edit tables, views, stored routines, triggers, and scheduled events. The query editor provides customizable syntax highlighting, code completion, SQL reformatting, and query history. Text files can be imported, while table rows can be exported as CSV, HTML, XML, SQL, LaTeX, Textile, PHP, Markdown, or JSON. Data can also be exported directly between servers or databases. Builds are offered for Windows, Linux, and macOS, including Linux x64 and arm64 packages, a macOS arm64 app bundle, and a Windows x64 portable edition. HeidiSQL requires an available database server or SQLite file; the requirements page says running through Wine is currently unstable and suggests native Linux instead.
