Vibe-coded and shipped yet another new tool!

Had fun making this, and as always, it was for work. I had to check my client’s pages for dead links, so this tool helps things along. And I can use it for my own sites too. Dead links affect your SEO, so always good to check periodically.
Everything was vibe-coded within an hour or two. And I didn’t even use Cursor for this! Just Perplexity’s sonar-pro on their playground site - it’s amazing how even the lesser-known LLMs are so capable now. And sonar-pro isn’t even for coding - it’s for web search!
The more tools I build, the more optimistic I get about AI as augmentation to human productivity.
Soon, we’ll print software for daily use, and discard it like it’s disposable.
Insane how far we’d come.

There’s probably something like this that exists already, but trying to find a version online that isn’t SEO optimized so much that it’s unusable… Yeah, you’re better off vibe coding and hosting it yourself.
Pretty cool. How easy would it be to create a tool like this to find dead email addresses?
