404Links.org aims to enhance the quality of free and open content by periodically scanning submitted pages for broken links. If any broken links are found, the service sends an email report to the submitter.
Submissions of various types of content, including Wikipedia pages, open-source software documentation, government websites, personal articles*, non-profit websites, and research sources are welcomed
If the page offers publicly accessible and valuable information—without endorsing products or services it's eligible for submission.
Upon submission, all pages undergo thorough checks to ensure compliance with our guidelines. Upon acceptance, you'll receive an email confirmation.
Accepted pages are scanned daily for broken URLs, and you'll be notified if any are found. However,notifications won't be sent for persistently broken links.
