SeaMonkey, the community-driven successor to Mozilla Suite, includes an HTML editor named Composer that is developed from the Mozilla Composer code contained in the original Mozilla Suite.

and incorporates Cascading Style Sheets support and other improvements from software company Disruptive Innovations. Nvu was the brainchild of Kevin Carmony, CEO for Linspire, who wanted an easy-to-use, WYSIWYG HTML editor for Linux users. Under Carmony's direction, Linspire started and sponsored Nvu, hiring Daniel Glazman, former Netscape Communications Corporation employee, to be the lead developer.

Development

The original plan in June 2005 was to merge back the numerous changes into Mozilla Composer's source code tree. Since then the Mozilla Suite has been discontinued (then reintroduced as SeaMonkey), and no one has merged the Nvu code back into Composer.

Shift to KompoZer

Daniel Glazman, the lead developer of Nvu, announced on September 15, 2006, that he had stopped official development on Nvu and that he was developing a successor as a Mozilla.org project. It is written from scratch and based on Mozilla trunk Gecko 1.9 and XULRunner. PHP and CSS would be supported. A community-driven fork, KompoZer, maintains Nvu codebase and fixes bugs until a successor to Nvu is released. Glazman's project is called BlueGriffon.

KompoZer

KompoZer is a discontinued open source WYSIWYG HTML editor based on the Nvu. KompoZer was forked as a community-driven project with development coordinated through SourceForge. KompoZer's WYSIWYG editing capabilities are one of the main attractions of the software. In addition, KompoZer allows direct code editing as well as a split code-graphic view. The most recent version is KompoZer 0.8 beta 3, released February 2010, using Gecko 1.8.1. The stable version was 0.7.10, released in August 2007. The only regular developer said in June 2011 that development "is stalled at the moment".One Year At INRIA - Kaz'hack
