RSS Validator

This service tests the validity of a Really Simple Syndication feed, checking to see that it follows the rules of the RSS specification.

Enter the URL of an RSS feed:

  • Server returned [Errno -5] No address associated with hostname [help]


An error occurred while trying to validate this feed.

Possible causes:

  1. The address may be incorrect. Make sure the address is spelled correctly. Try loading the feed directly in your browser to make sure a feed exists at that address.
  2. The feed may be temporarily unavailable. The server may be down, or too slow. Try again later.
  3. The validator may be busted. If the feed exists, the server is fine, and the problem is reproducible, let us know on the feedvalidator-users mailing list.
