SocialSpec Validator

Enter a domain to check whether it publishes the three SocialSpec files under /.well-known/ and whether each follows its format. Everything runs in your browser — a file can only be read if the site sends the CORS headers the spec requires, so CORS is verified too.

SocialSpec is a set of drafts:
followspec.org · aboutspec.org · contactspec.org
Checks performed: reachability, Content-Type, CORS, and basic structural validity (no exhaustive schema validation).
