HeidiSQL is a free MySQL front-end. It is an easy-to-use interface and a "working-horse" for web-developers using the popular MySQL-Database. It allows you to manage and browse your databases and tables from an intuitive Windows interface.
HeidiSQL now uses a more lightweight database layer to access MySQL servers. This completely new written layer consists of just two units and replaces the big ZeosDBO package - which worked well over the years, but I felt that here and there developping new features regarding the libmysql API was a pain.
