siteOS

siteOS is a website monitoring platform for developers and site owners. It crawls every page of your site on a schedule - sitemap plus internal links - and surfaces broken links, missing meta tags, canonical issues, and other SEO problems, graded by severity into a 0-100 Health Score. Connect Google Search Console to see 16 months of clicks, impressions, CTR, and position next to your crawl data. Get alerted the moment something breaks instead of finding out from a user (or from Google). The crawl engine is open source: @site-os/check is an MIT-licensed TypeScript CLI you can run against any URL, a static build folder, or in CI to fail the build on regressions. Built for teams: projects, roles, and API keys included.
