    Hi HN, I run an affiliate site with hundreds of outbound links. Over time, these links break — products go out of stock, vendors change URLs, and sometimes media just disappears. I got tired of manually checking them, so I built check-my-links.com ...my first NextJS project. It scans my site regularly and flags broken links, missing images, or redirects — so I can fix them before users (or SEO bots) notice. It started as a tool for myself, but I figured others might find it useful too. Happy to answer questions or get feedback! Why did I not use existing tools? - Google Search Console…
