KompoZer is a discontinued open source WYSIWYG HTML editor based on the Nvu editor, which was itself derived from the Composer component of the Mozilla Application Suite.[1] 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".[2]

Starting from macOS Catalina it is no longer supported on MacOS.

Standards compliance

KompoZer complies with the W3C's web standards. By default, pages are created in accordance to HTML 4.01 Strict and use Cascading Style Sheets (CSS) for styling, but the user can change the settings and choose between:

  • Strict and transitional DTD's
  • HTML 4.01 and XHTML 1.0
  • CSS styling or the old <font> based styling.

The application can call on the W3C HTML validator, which uploads pages to the W3C Markup Validation Service and checks for compliance.
