* Ansgar Becker began development on a MySQL front-end in 1999, naming the project "MySQL-Front" and using a direct [[API]] layer written by Matthias Fichtner<ref>{{cite web |url = http://www.fichtner.net/delphi/mysql.delphi.phtml |title = Client API for MySQL Database Servers |publisher = audio-data.de |author = Matthias Fichtner |accessdate = 2014-12-01 |date = 2011-09-15 |archive-url = http://webarchive.loc.gov/all/20020808163649/http://www.fichtner.net/delphi/mysql.delphi.phtml |archive-date = 2002-08-08 |url-status = dead }}</ref> to interface with [[MySQL]] servers and the databases contained on them. Private development continued until 2003 with version 2.5.
* In 2004, during a period of inactivity, Becker sold the MySQL-Front branding to Nils Hoyer, who continued development by [[clone (computing)|cloning]] the original software.<ref>{{cite web|url=https://www.heidisql.com/forum.php?t=20155|title=the truth about heidiSQL history in wikipedia|website=www.heidisql.com|access-date=2017-05-22|archive-date=2016-02-19|archive-url=https://web.archive.org/web/20160219031506/http://www.heidisql.com/forum.php?t=20155|url-status=live}}</ref><ref>{{cite web|url=https://www.heidisql.com/forum.php?t=23|title=Zu: Announcement: End of MySQL-Front ?

* In April 2006, Becker [[Open-source software|open-sourced]] the application on [[SourceForge]], renaming the project "HeidiSQL" due to having sold the MySQL-Front branding. HeidiSQL was re-engineered to use [[ZeosLib]], a newer and more popular database-interface layer, which debuted in version 3.0.
** 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]]''.<ref>{{cite web |title=heidi? |url=https://www.heidisql.com/forum.php?t=19 |url-status=live |archive-url=https://web.archive.org/web/20190331104119/https://www.heidisql.com/forum.php?t=19 |archive-date=2019-03-31 |access-date=2017-05-22 |website=www.heidisql.com}}</ref>
* The database layer was again replaced by a single-unit approach{{Clarify|date=July 2024|reason="Single-unit" is not used elsewhere, so it's unclear what it means to return to this approach.}} in October 2009 by Becker. Later, this was again extended for supporting other database servers.
* jHeidi—a version written in [[Java (programming language)|Java]] was designed to work on Mac and Linux computers—was discontinued in March 2010 in favor of [[Wine (software)|Wine]] support.
* 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]].
* [[SQLite]] support was introduced in March 2020 for the 11.0 release.<ref>{{cite web|url=https://www.heidisql.com/forum.php?t=35807|title=HeidiSQL 11.0 with SQLite support|website=heidisql.com|access-date=2023-05-15|archive-date=2023-05-15|archive-url=https://web.archive.org/web/20230515200549/https://www.heidisql.com/forum.php?t=35807|url-status=live}}</ref>
