KompoZer, built on the NVU architecture, is a good free option that is beginning to approach the functionality of Dreamweaver.

KompoZer’s three-tier toolbar is intuitive yet powerful.

The interface is different than Dreamweaver’s, but it should still feel familiar. Major editing buttons live in a three-tier toolbar at the top of the program that includes a one-click Publishing icon as well as one-click buttons for Image insertion and Table and Form creation. Font tweaks like Size and Style live in toolbars just below for easy HTML editing. A Site Manager, including File tree, is anchored on the left, although it can be collapsed. We didn’t notice any screwups when playing with the WYSIWYG function. Running lean and mean lets KompoZer compete more than adequately with better-known competitors.
