W3C Link Checker

https://validator.w3.org/checklink

HTML | Tool

The W3C Link Checker crawls your website and reports broken or outdated links. The tool reports on broken links (e.g., 404), broken or missing websites, and links which should be updated to a new location.

Many more W3C checkers exist, for example HTML, CSS, or RSS validation. https://w3c.github.io/developers/tools/ provides an overview.
