Hi HN,
We have been building DNSArchive (a DNS repository) and just made the public (out of beta), our web security metadata search.
It allows you to look for specific patterns on headers, links and other hard to find parts of web sites.
For example, you can search for all sites using PHP/5.2:
https://dnsarchive.net/web-search?q=PHP/5.2
Or WordPress 5.2:
https://dnsarchive.net/web-search?q=%22Wordpress%205.2%22
Or search fro web servers that have Ubuntu displayed on the web server header:
https://dnsarchive.net/web-search?q=ubuntu
Feedback is very welcome. We did a Show HN about it a few months ago and got no traction and sending it again since we just pushed multiple updates and added over 150m sites there.
