Original Summary

https://heade.rs It started as a quick way to check a site's HTTP headers (hence the name) and turned into the page I wanted every time I got curious about a website. Type in any domain or IP and you get where it's hosted (down to the cloud region), the route your traffic takes to get there, how fast it answers from where you are, who registered it, what it's built with, whether its email can be spoofed, and which AI crawlers it lets in. Free, no sign-up, no ads. I'd love feedback, especially on anything it gets wrong about your own site.   submitted by   /u/colinarms [link]   [comments]
