There are no differences other than the set of supported plugins. For example, IntelliJ IDEA Community Edition does not include the JavaScript plugin, so any plugins that depend on it will not work in IntelliJ IDEA Community Edition.
Just to clarify, If I developed plugin using community edition that's plugin has to be worked in commercial version also, without causing any issues right?
