Seodar
Seodar is a technical SEO platform. It crawls a site, scores its health against 195 technical checks, and ranks the fixes by how much score each one returns for the effort involved - so teams work from a priority list rather than a dump of issues. Every finding says why it matters and what to change.
Beyond the audit it covers keyword research and rank tracking, competitor comparison scored by the same checks, backlink data, Google Search Console and Bing Webmaster integration, WCAG 2.2 accessibility checks on rendered pages, uptime and regression monitoring, URL segments and custom rules.
It also measures AI visibility: whether ChatGPT, Claude, Gemini and Perplexity know a site and cite it, and whether it appears in Google AI Overviews.
Agencies can white-label the interface and the scheduled PDF reports their clients receive. There is a REST API and a WordPress plugin. Any site can be scanned free, with no account and no card.

SEOSage
SEOSage is desktop SEO audit software that crawls every page of your website with no page limits. It runs on your own computer (Mac and Windows), so your crawl data stays with you and you can audit large sites, staging sites and password-protected sites. After a crawl you get one health score and a ranked list of every issue. Each issue explains why it matters, how to fix it and which pages are affected. Fix a page, press re-check, and SEOSage tells you whether the problem is gone, without crawling the whole site again. The app also includes Core Web Vitals tests for mobile and desktop, Google Search Console data (read-only), competitor tracking, crawl comparison, a site map, internal link scores and an optional Claude connection for plain-English questions about your audit. Reports export as PowerPoint, PDF, CSV or Markdown with your own colours and logo. Free for 14 days with no card needed, then plans start at $9 a month.
