Claris Home Page was a WYSIWYG HTML editor available for the classic Mac OS and Microsoft Windows. It was a low cost, entry level program that allowed users to easily create, upload, and manage websites. The last revision came out in 1997, and while it doesn't create standards compliant HTML, it tends to produce code that works well across browsers.
At this point, the free KompoZer seems to be the best replacement for this aging (but still useful) program.
