Nvu is the Mozilla Composer spun off into its own product, like MozillaFirefox is to the WebBrowser component and MozillaThunderbird to the MailClient. It adds new features like integrated web site management, better form and a CSS editor to fill the space that !FrontPage? or Dreamweaver occupy on Windows.

Versions are available for Windows and Linux.

It exists due to the generosity of Linspire (nee Lindows) and their want to offer a web authoring tool on their OS. It is written mostly by Daniel Glazman, the lead Mozilla Composer developer, who is contracted by Linspire to write it.
