A great alternative to successful commercial WYSIWYG HTML editors, this program is a must-have among the web development community for easy and quick HTML editing with support for templates, FTP transfers, tabbed editing and for most HTML elements like divs, tables, forms and other tags.

Like anyone would expect a modern WYSIWYG editor to do, KompoZer can style your elements in an almost unlimited amount of ways. It supports CSS, applying styles to elements (like spans or divs) and styling your page to look neat and professional. This can all be done in the 'design' view. For those with a little more experience in editing HTML, you can also use a source-only view or a split layout while being able to edit the raw html and preview it at the same time.

For those new to web page editing, you might be surprised to learn how easy KompoZer makes it to position elements. You can place images, text, headings and virtually any else in a layer and position it on the web page anywhere you'd like by clicking the layer button (in the top-right corner) and moving the newly created layer with your cursor.

If you're coming from experience with Adobe Dreamweaver, be prepared to say hello to not only lightning fast loading and editing work, but also a rather familiar layout, albeit in a vastly different order. With hardly any real serious contenders these days for web editing besides Dreamweaver, KompoZer is truly a gem, especially when Dreamweaver has your high-end system bogged down for simple rendering.

What blew us away was when we pasted the source of Canadian Content's home page into the source window of KompoZer, it rendered almost immediately. When doing that with Dreamweaver, it almost leads to a system crash and can take over a minute in Dreamweaver.

KompoZer is a project forked from NVU, another open source web editor. It is far from just a simple editor and combines great HTML editing tools while keeping the program fast. The speed of KompoZer can be attributed to collaborative community development. Just like the software itself, KompoZer is powered by Gekco, the open source Mozilla backend.

Overall, if you're a professional with years of experience and prefer to preview your work while coding HTML or you're just getting started with creating web sites, KompoZer is suitable for nearly anybody.

A note about KompoZer: A lot of time and work went into making this software available. If you use it, please consider donating any amount to help continue the development.
