Komodo

Komodo from ActiveState was the IDE that I used when writing Python and Javascript. It does support other languages. PHP for example. I just don't do much programming in the other languages it supports.

I am using Microsoft Visual Studio Community Edition now when working on Windows.

On Linux I have switched to using Spyder. Spyder is not better than Komodo, just a different approach. The debugger in Komodo is better than Spyder.

Spyder does not require administrative rights to install on Windows, which is a big plus because that's frequently an obstacle for me.
