LinkChecker

I was sorting through my bookmarks recently and found websites with similar functions, but they require login and captcha input which is quite inconvenient to use, so I spent some time building this web tool myself.

I’ve also added some small filtering features to the basic link check to make results more intuitive, and included RSS check functionality for blog audits for convenience. More link check features can be added later if needed.
This tool may not detect asynchronously loaded additional links, as link extraction is done in a single pass, but the overall check performance is better than I expected. Developers who need this are welcome to give it a try!
