Linkguard features
🕷️ Real crawler
Give it a start URL plus depth and page limits and it walks your internal pages with undici, no headless browser, checking every internal and external link it finds.
🔀 Redirect-chain analysis
Follows redirects hop by hop, stores the full chain, and flags anything over two hops so you catch link-equity leaks.
📋 Filterable results table
URL, status code, hops, link text and the pages each link was found on, filterable to broken, redirects, over two hops, or OK.
🔁 Scheduled re-crawls with diffs
Daily or weekly re-scans diffed against the last run, so you get new-broken-links-since-last-scan instead of a raw dump.
✉️ Email alerts only on new breaks
SMTP alerts fire only when new broken links appear, so there is no alert fatigue.
📤 CSV export
Export any scan to CSV for client reports.
🤖 Polite by default
Respects robots.txt Disallow and Crawl-delay, with a configurable crawl-delay and a concurrency cap of 1 to 20.
$24 once — that's the whole pricing page
Ahrefs Site Audit charges $99+/mo — roughly $1,188 a year, every year. Linkguard is a single payment, and it keeps working whether or not we ever sell another copy.

Honest answers
Is it really free on GitHub?
Yes. Linkguard is MIT-licensed at github.com/bensblueprints/broken-link-checker-mvp and always will be. The $24 buys the packaged 1-click installer and setup; building from source is free.
Where does my scan data live?
In a SQLite file on your own server. Nothing is uploaded to us or anyone else, so your crawl data never leaves your infrastructure.
Is there a page or crawl limit?
No metered limit like the subscriptions charge for. Your crawl size is bounded only by your own hardware.
