KompoZer is an open source WYSIWYG HTML editor based on a rewritten version of the now-discontinued Nvu editor. KompoZer is maintained as a community-driven fork and is a project on Sourceforge.

The actual release, KompoZer 0.8 beta 3, has been updated to Gecko 1.8.1, and code is almost ready for final users.

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.
