KompoZer is a free, open source WYSIWYG Web page authoring tool similar to that of Microsoft FrontPage and Adobe Dreamweaver.

Who’s it for?

KompoZer is for anyone who wants to develop or manage a Website that does not use a pre-built CMS or Portal tool. KompoZer can be used without any knowledge of HTML, CSS, or any other Web-based language, but if you happen to know those languages, all the better. Individual users, SMBs, and enterprises can all benefit from KompoZer. If you are familiar with FrontPage or Dreamweaver, you will be right at home with KompoZer.

What problem does it solve?

KompoZer solves multiple problems. Primarily it allows the user to easily create Web sites using a full-blown WYSIWYG tool. But KompoZer is not limited to drag-and-drop Web authoring. KompoZer allows serious Web designers, builders, and architects to manage complex sites quickly and easily. And it does this without the costly license fees you often get when using the competition, because KompoZer is free.

Standout features

  • Tabbed editing allowing you have multiple pages or sites open in one window.
  • Integrated file management via FTP.
  • Forms, tables, and template support.
  • Color picker helps you to quickly know the hex values of the colors you need.
  • CSS editor allows you to see your CSS changes live.
  • Markup cleaner works in conjunction with the WC3 validation tool to make sure your markup is clean.
  • Automated spell checks keeps you from looking unprofessional.

What’s wrong?

One of the first things a more seasoned user will notice is that KompoZer doesn’t have all of the bells and whistles included in Dreamweaver. For instance adding Flash objects with KompoZer isn’t as easy as it is with Dreamweaver. That, of course, is a minor issue. The bigger issue is that KompoZer doesn’t work with Dreamweaver template files. This can cause a problem because a lot of clients use Dreamweaver templates.
