Geany

Geany is a small and lightweight Integrated Development Environment. It was developed to provide a small and fast IDE, which has only a few dependencies from other packages. Another goal was to be as independent as possible from a special Desktop Environment like KDE or GNOME - Geany only requires the GTK3 runtime libraries.

It runs on Linux, Windows and macOS is translated into over 40 languages, and has built-in support for more than 50 programming languages.
