Some of the very best web design and development tools are free. Free as in speech and as in zero pence. We take a look at the best free software you can use to build a successful, contemporary website, starting with the obvious: tools to design it with.

First you’ll need a web editor. Nvu has long led the field in open source drag- and-drop web authoring. However, development seems to be frozen, with no new releases since 2005. KompoZer builds on the same code base and is described as “Nvu’s unofficial bugfix release”. It might feel like an earlier version of Dreamweaver, but with CSS editing and built-in W3C validation, it’s a modern authoring tool. Both are available for Mac, Windows and Linux.
