👋 Hi Product Hunt! This is my first product — I coded it myself this summer, and it already has 500+ users. Broken Link Checker scans any webpage to find and highlight dead links (404s, redirects, outdated URLs). You can export results to CSV for easy reports. It works entirely in your browser — no data leaves your computer, nothing is sent to any server. My next goal is to add full-site scanning, not just single-page checks. Would love your feedback and ideas for what to build next! 🚀

Congratulations on the launch.

A few thoughts I have in mind.

- A video would be super helpful, actually, I cannot understand how it works, like do I put my website URL and the link checker looks into the web links in that page? Or is it that I give my website link and it recursively checks all the link paths of my website? Like it checks example.com, then it checks example.com/index and so on. I think it's the first one?
- The chrome app is great but if you package it as an SDK, any developer could use it in their project. The developer just needs to feed in the routes, and your SDK would poll after intervals and alert the devs. This can work with your initial idea of checking it for only a page.

Looks super useful and promising though. All the very best!

@prastik Thanks!

You understood it right — for now the extension checks only the current page. You open any webpage, run the tool, and it scans all links on that page to detect broken ones.

I’m planning to expand it to crawl entire websites, not just single pages — that’s the next step.

I really appreciate your SDK idea. That’s a great direction for the future! I decided to start with a simple Chrome extension because I had zero development experience, and it was an achievable first step.

As the project grows, I’ll definitely think about more advanced tools and integrations. Thanks again for the thoughtful feedback! 🙏
