KompoZer Portable is a versatile HTML web page editor and standalone portable web authoring tool designed to run directly from a USB flash drive. Based on the popular Nvu editor, this free html editor fixes many of Nvu's bugs and stability issues, making it a more reliable and user friendly solution for offline web development.
This portable web editor is especially appealing to users familiar with classic web design software such as Adobe Dreamweaver or Microsoft FrontPage, offering a visual WYSIWYG interface without requiring constant internet access.
KompoZer Portable Web Page Editor
KompoZer Portable is a free and open source WYSIWYG (What You See Is What You Get) HTML editor that allows users to visually design and edit web pages without deep knowledge of HTML or CSS. It is an offline website builder, meaning pages can be created, edited, and previewed locally before being uploaded to a web server.
The name "KompoZer" is derived from "composer," reflecting its role as a visual web page composition tool. Unlike modern browser based editors, it operates entirely on the local system, making it ideal for use on shared computers, restricted environments, or portable workflows.
Background and Development History
KompoZer originated as a fork of the Nvu web editor, which was originally developed by Linspire. When Nvu's development slowed and eventually stalled, Daniel Glazman continued the project, fixing bugs, improving stability, and releasing KompoZer as a more polished alternative.
The first official release of KompoZer occurred on August 30, 2007. Although the last stable release dates back to February 28, 2010, the editor remains usable for basic and intermediate website creation tasks. Its portable edition, packaged by John Haller, allows it to be run directly from removable media such as USB flash drives.
