HeidiSQL is a free and open-source administration tool for MariaDB, MySQL, as well as Microsoft SQL Server, PostgreSQL and SQLite. Its codebase was originally taken from Ansgar Becker's own MySQL-Front 2.5 software. Due to having sold the MySQL-Front branding to an unrelated party, Becker chose "HeidiSQL" as a replacement. The name was suggested by a friend as a tribute to Heidi Klum, and was further reinforced by Becker's own nostalgia for Heidi, Girl of the Alps.
Ansgar Becker began development on a MySQL front-end in 1999 naming the project "MySQL-Front" and used a direct API layer written by Matthias Fichtner to interface with MySQL servers and contained databases. Private development continued until 2003 with version 2.5.
In April 2006, Becker open-sourced the application on SourceForge, renaming the project "HeidiSQL". HeidiSQL was re-engineered to use a newer and more popular database-interface layer, ZeosLib, which debuted in version 3.0.
The database layer was again replaced by a single-unit approach in October 2009 by Becker. Later, this was again extended for supporting other database servers.
Support for Microsoft SQL Server was added in March 2011 for the 7.0 release.
Since the 8.0 release, HeidiSQL offers its GUI in about 22 languages other than English. Translations are contributed by users from various countries via Transifex.
PostgreSQL support was introduced in March 2014 for the 9.0 release.
In early 2018, a slightly extended v9.5 release was published on the Microsoft Store.
