Your README's demo link is dead and nobody told you.
Launch day. Your README is live, the demo link everyone clicks first goes nowhere — the repo moved, the docs page got renamed, nobody noticed during review. Link rot is quiet until it isn't. md-link-check is a fast, local-first link checker for markdown.

Your README's demo link was dead, but nobody informed you about it. The link rot went unnoticed until it became a problem. md-link-check, a fast local-first markdown link checker, reveals broken links in your README and docs folder before your readers encounter them. By checking the markdown files, md-link-check flags broken text links, image sources, reference-style links, autolinks, and bare URLs.
It decodes %20 -style paths and follows redirects, exiting with a non-zero code when broken links are found. This tool is helpful for CI pipelines, sandboxes, and offline environments, and it is written in Python 3.9+ using the standard library.
