Ranked in these QuestionsQuestion Ranking
Pro Light and fast
Geany is very lightweight thanks to the smaller offering of features.
Pro Built-in plugin manager
Geany has a built-in plugin manager which can be used to install plugins and add new powerful features to the editor.
Pro Simple project management
Pro Cross platform
Geany is a cross platform editor, very similar to Notepad++ in Windows.
Pro Build in terminal
Press F5 and code will run without the need to switch between windows.
Pro Actively developed Open Source
Which usually means it will remain free of charge.
Pro Quick search on large files
In Geany you technically search once for a whole search query, unlike Gedit, where once you start typing, the file is searched for in accordance with each substring of what you're typing, all the while leading to terribly annoying lag.
It is a real app and not another frankenstein web/electron app.
Pro Options in the menu are easy to find
For example, there is an easy way to change the font and theme in the View menu. No need to search through several syntax styles like in Notepad++ just to be able to change the used font.
Pro Real syntax parsing (not just coloring)
Hence it is capable of showing the methods and inner classes of, e.g., a Java source file.
Pro Free and open-source
Released under the MIT license.
Pro Graph plotting support
Spyder can plot graphs and provide the list of all variables.
Pro Relatively lightweight
Pro Powerful autocompletion
Spyder's autocomplete features are made possible by a library called rope which gives Spyder powerful autocompletion.
Pro Has support for Vim bindings via plugin support
Aside from being an open sourced, actively developed IDE, vim key-binding support is also available. If you remember Pydee - this is it, albeit with a new name.
Pro Helps you to use documentation
Pro Enables to write consistent code
Pylint integration enables to check the code for PEP8 style guide and detect errors.
Pro Has cross platform support - Linux, Mac, and even Windows
Spyder (formerly Pydee) has support for all of the major operating platforms - Linux, Mac, and even Windows.
Pro Intuitive interface
Pro Good GitHub project
Pro Excellent variable explorer
Dynamic variable explorer with editor and visualizer
Pro Completely Python
Con Not very advanced
Similar to Notepad or Gedit.
Con Not many third-party plugins
Geany is not as popular as some other text editors with plugin support. As such it's understandable that it's missing lots of powerful plugins available in other editors.
Con Windows installer not digitally signed
Con Not beautiful
The default theme is not beautiful. And there are not many themes.
Con The documentation is poor when it comes to debugging
Not a lot of information about debugging is available in the documentation.
Con Consumes a lot of memory
If you're working with large data, especially arrays, another IDE should be considered as spyder uses at least 200-300Mb of memory.
