BlueGriffon: New WYSIWYG content editor for the WWW
Powered by Gecko, the rendering engine of Firefox, it’s a modern and robust solution to edit Web pages in conformance to the latest Web Standards.
It’s free to download (current stable version is 1.7) and is available on Windows, Mac OS X and Linux.
Because Gecko lives inside BlueGriffon, the document you edit will look exactly the same in Firefox. Advanced users can always use the Source View to hard-code their page.
BlueGriffon is tri-licensed under the Mozilla Public License 1.1, the GNU General Public License Version 2 and the GNU Lesser General Public License Version 2.1.
