Texmaker is a free, modern and cross-platform LaTeX editor for linux, macosx and windows systems that integrates many tools needed to develop documents with LaTeX, in just one application. Texmaker includes unicode support, spell checking, auto-completion, code folding and a built-in pdf viewer with synctex support and continuous view mode.
TeXstudio is a fork of the LaTeX IDE TexMaker and gives you an environment where you can easily create and manage LaTeX documents. It provides modern writing support, like interactive spell checking, code folding and syntax highlighting. Also it serves as a starting point from where you can easily run all necessary LaTeX tools. (you can see more features below) You can run it on Windows, Unix/Linux, BSD and MacOSX systems and modify it if you want, since it is licensed under the GPL. Althought TeXstudio has a lot of additional features, it tries to be like an improved version of Texmaker, so it keeps it look&feel as well as its version number.

CKEditor and FCKeditor
FCKeditor has been around for more than six years. Since 2003 it has built a strong user community becoming the most used editor in the market, accumulating more than 3,5 million downloads. On 2009, we decided renaming the editor, bringing to the light our next generation solution: CKEditor 3.0.
