LinkRotAlert – Dead link and content drift monitor

Monitors broken links and content drift in technical docs for individuals and small teams

Problem

Technical docs, blogs and open-source READMEs contain many outbound links. Over time they break or silently point to changed content, but individuals and small teams lack budget for continuous link checking. An HN post shared a tool for fixing stale references in docs, confirming this is a real and under-served scenario.

Solution

A lightweight SaaS + GitHub App that periodically crawls outbound links in your docs site and repos, detects 404s, redirect chains and semantic content drift (e.g. a link now points to a promo or unrelated page), and alerts via dashboard or Slack.

Users

Individual developers and 1–10 person teams maintaining technical blogs, docs sites or open-source projects.

MVP

Input a sitemap or Git repo to auto-extract all outbound links; weekly check of HTTP status, redirects and page title/summary changes; simple similarity score for content drift; email or Slack weekly digest; one-click create GitHub issue for fixes.

Revenue

Free tier up to 100 links; personal $5/month unlimited; team $15/month with multi-repo and Slack integration.

Why now

Content and link lifespans are shrinking, and AI-generated content is making 'link replaced by unrelated page' more common, while mainstream tools remain enterprise-grade dead-link checkers with no lightweight option for small creators.
