In plain words

Dr. Link Check is a web-based tool that crawls websites to identify broken links, invalid SSL certificates, and links to malicious sites. It automatically scans HTML and CSS code starting from a given URL and generates reports highlighting problematic links that need attention. The tool helps website owners fix 404 errors, typos, and suspicious URLs that could harm visitors or damage search engine rankings.

From the sources

Non-working links are annoying and reflect poorly on your professionalism. They not only deter visitors from staying on and returning to your site, but they can also negatively impact your search engine rankings. Even worse than a broken link is a link to a website that causes harm through malware or phishing. Instead of manually checking all the pages of your site and clicking through all the outgoing links, let Dr. Link Check do the work and give you a report of the links that need your attention. Beginning with a start URL, our bot crawls through the HTML and CSS code of your entire website and examines all the links it can find. This includes internal page links and outbound links to…from drlinkcheck.com

    Yes, it's open source: https://github.com/lissy93/web-check :) Why I'm building this? There are a lot of tools out there for discovering meta and security data relating to a website, IP or server. But currently, there isn't anything that does everything, all in one place and without a paywall/ user sign up. It's still a WIP, and I'm working on a new version, with some more comprehensive checks, so any feedback would be much appreciated :)
