CrawlCenter
CrawlCenter is a powerful cloud-based app you can use to find On-Page SEO issues on your site. The app crawls your site on the click of a button and gives you access to 15+ SEO reports for free. CrawlCenter crawls your website and saves the website data in the database. The time taken by the crawler to crawl the site can be few seconds or minutes. Once your site has been crawled, CrawlCenter will open the pages of the report automatically. The SaaS uses the website data to generate 15+ reports. The user must view the reports and filter the data to find On-Page SEO issues on their websites. CrawlCenter makes its users aware of the broken internal and external links. If you use this app, you can get rid of broken link checker plugins/extensions (if you're using them). With CrawlCenter, you can find out the pages on your website with duplicate meta description, title, and keyword tags.

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, then plans start at $19 a month.
