## What it is
Linkinator is a broken link checker that crawls websites, local HTML files, and markdown documentation to find dead links and invalid URLs. It provides both a Node.js API and a CLI, with standalone binaries and Docker images available.

## Use cases
- find broken links on my website
- check markdown docs for dead links
- run a link check in CI/CD pipeline
- audit site for 404 errors for SEO
- validate links in local HTML files
- crawl a site and report dead URLs

## When to choose
- you need a fast, scriptable link checker with CLI and API
- you want to integrate link validation into CI/CD
- you need to scan markdown files or local HTML without a server
- you want standalone binaries or Docker without Node.js installed

## When to avoid
- you need a full SEO audit beyond link checking
- you need a GUI-based crawler with visual reports
- you need JavaScript-rendered SPA crawling with headless browser support
