Rarchy offers a suite of website planning tools, including visual sitemaps and user flows, designed for agencies and teams.
The core product is our free visual sitemap editor, which allows you to create a sitemap from scratch or import your existing website pages via our visual sitemap generator. You're then able to view your website in five different visual formats, use the drag-and-drop interface to make changes, and auto-capture screenshots of your current page designs. Your sitemap can be exported to XML (ready to upload to search engines), CSV, or PDF format.
Rarchy is ideal for teams, allowing you to collaborate, revise, and communicate changes to your website in one place.

Looking at the html of HN's pages, can't blame them really. Running though https://validator.w3.org/ , the result is abysmal. At this rate, if web browsers started requiring sites to output HTML that is somewhere in the realm of normalcy, HN would sooner shut down than consider ever updating. - Source: Hacker News / 15 days ago
Whether you’re a frontend developer, lead, or manager, reconsider your expectations and practices if you haven’t yet chosen not to ship erroneous HTML. The more of us decide to talk about using actual HTML on our sites and in our apps, and lead by example, the better for our users and clients, and the better for our craft and profession. On the engineering side of web development, it’s HTML first—if it is HTML. - Source: dev.to / 28 days ago
