Constructed internal link checker that detects dead links prior to going live

I continued pushing documentation and landing pages containing broken internal links since no one will notice until the user clicks. That's why I developed a simple utility to crawl the website before deployment and to notify about all those pointing links, including redirects that silently perform four hops before returning results.

No fancy stuff. It does not use any AI technology, nor does it do anything generative. I understand it won't sound appealing in a thread full of AI-related projects, but I'd prefer real feedback to compliments.

If you maintain websites with a couple of pages or more, could this be a problem for you? Or does your CMS or CI process already deal with that? If there's an interest, I am happy to send you a link.
