What is HeidiSQL?
HeidiSQL is free software for people who work with databases, and aims to be intuitive to use. "Heidi" lets you connect to a variety of databases, like MariaDB, MySQL, Microsoft SQL, PostgreSQL, SQLite, Interbase and Firebird. Once you are connected, you can edit data and structures in these databases. Invented in 2002 by Ansgar, HeidiSQL is still a popular tool for MariaDB and MySQL, and actively maintained. Current Delphi version for compiling HeidiSQL is v12.1.
