From Basepath Associates:
SiteKite is a simple HTML editor and FTP uploader that can be used to build and maintain a website. It's ideal for those new to website building who want a tool that's easy to learn, yet powerful enough to do the whole job. SiteKite is somewhat inspired by the outline+editor approach widely used in editors like BBEdit and XCode, combined with built-in FTP and web preview, like BBEdit, FrontPage, and many other other website builders. The chief design goal was to make it as easy to setup and use as possible, so it can serve as a follow-on app to HTMLteacher (just above).
