@hendry Your comment reminded me of this discussion we had previously -

Link Checker for Go/Hugo?

This isn’t so much a feature request (seems a little out of place for something like this to be built into Hugo), but does anyone have any suggestions for link checking when creating large, static sites with Hugo? I have chrome extensions for individual pages, and there are obviously services that can take care of this, but paying for anything seems like a waste of $$. Thanks!
