Detect new and removed pages on a competitor's website
Owlabee
Compares a site's sitemap with the snapshot from the previous run and reports new-url, removed-url and lastmod-changed records, without fetching the pages themselves, so it is fast and cheap enough to run daily on large sites. The first run stores the baseline (here sitemaps.org); point it at a competitor's sitemap and add a webhook URL to be told when they launch a page.
