About this tool

Brokenlink is an automated broken link checker that monitors every URL you care about around the clock and alerts you by email or Slack the moment one dies — so a broken link never sits unnoticed for days, weeks, or months.

A free one-off link checker only tells you about today. Brokenlink re-checks continuously, tracks each link's status history, and reports the exact URL and status code the moment something breaks. Set it up once and never check a link by hand again.
