Microsoft split Frontpage in two products SharePoint Designer and Expression Web (the later with a new web render engine), though both products are either a shadow of the former self (no WYSIWYG view anymore) or abandoned (free download without support): https://en.wikipedia.org/wiki/Microsoft_Expression_Web
