orphan-beacon
Find the pages in your built static site that nothing links to, and measure how many clicks every page is from the homepage.
Find orphan pages in your built static site and measure click depth from the homepage: pages with no internal inbound links, unreachable clusters, nofollow-only or noindex-only links, pages too deep, dead ends. Text/JSON/SARIF/Markdown, allowlist with expiry, GitHub Action. Zero deps.

Why it exists
Search engines discover and weigh pages through internal links. A page that only exists in the sitemap, a blog series that only links to itself, or a product buried six clicks deep gets crawled rarely and ranks poorly. orphan-beacon builds the internal link graph from your built HTML, walks it from the homepage like a crawler, and reports orphans, unreachable clusters and deep pages with the file, severity and a concrete fix.
CLI, library and GitHub Action. Node.js 18+, zero runtime dependencies. Works on any static build output (Astro, Next.js “output: 'export'”, Eleventy, Hugo, Jekyll, Docusaurus, VitePress, plain HTML) and runs offline: point it at the folder your build writes. By Louis Wright.
Features
Reachability
pages that are linked, but only from a cluster that the homepage cannot reach; pages linked only with rel=nofollow/ugc/sponsored; pages linked only from noindex pages; pages only reachable via javascript:/onclick navigation.
Click depth
breadth-first shortest path from the homepage (or --start) following crawlable links; pages deeper than --max-depth (default 3).
Link equity hints
pages with a single inbound link (info) and dead-end pages with no outgoing internal links.
