The basic version of the editor is free. There are some plugins form Drupal, Joomla, Smarty, WordPress, JQuery and CodeIgniter at reasonable price. I never needed those so I haven’t tried them, but for someone who us coding a lot on these platforms it might be a good option.
Before CodeLobster I used CrimsonEditor for years but it really had a lot of problem and even it’s inheritor Emerald Editor still has most of them. CodeLobster is far more advanced, has Class and Functions view, good cross-file search, auto-complete, excellent syntax highlight and good auto-indentations.
At this point the main problem with it is that it crashes often without any reason. Hopefully the guys will fix that in some of the next version.
