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 GTK2 runtime libraries.
- Geany in functionality and interface is very similar to Notepad++
- Simple, lightweight. But there're syntax highlighting and code completion.
- Free, lightweight, multi platform, open source, customizable. What more do you want?
