More than 70 automated checks sniff out broken links, redirect chains, and missing meta tags across your whole site, and SEOnaut, the self-hosted SEO audit crawler, sorts every finding into critical, alert, or warning so you know what to fix first. Add a website as a project, press Crawl Now, and watch URLs stream in with their status codes; a Stop button ends any run that wanders off. Reports also cover duplicate titles and descriptions, heading order, hreflang, canonicals, image alt text, thin content, orphan pages, and non-HTTPS URLs, while a passed-checks list shows what is already healthy. Dashboard charts follow crawl history, issue trends, status codes, link types, and page depth. Crawl options are set per project: ignore robots.txt, follow nofollow links, include noindex pages, read the sitemap, allow subdomains, check external links, or authenticate with HTTP Basic to audit a password-protected staging site. Page Details opens any URL with its inlinks, outgoing links, redirections, and images, and URL Explorer searches the crawled pages by term. Export sitemap.xml, CSV lists, or a replayable WACZ archive. Each person picks a light or dark theme and one of five interface languages.
