SiteHaul

Browser extensions capture one tab at a time and you name every file yourself. Hosted services render your client's pages on someone else's servers. SiteHaul reads a site's sitemap and captures every page at desktop and mobile in one run, named from each URL, entirely on your Mac. Nothing is uploaded, no account. It also exports each page's copy as Markdown and a urls.md redirect map. Free for 50 pages a month, $49 once.
