HubSpot Content Hub: vendor profile

In short

HubSpot's pages for Content Hub cover error pages, robots.txt and sitemaps, and stay silent on llms.txt, markdown and rendering. Landing pages join the sitemap by hand. Starter costs $20 a seat a month, shown at $10 for new customers, and has no drag and drop template for a custom 404.
