Difference between http://jigsaw.w3.org/css-validator/ and http://www.css-validator.org/ CSS validators?

stackoverflow.com › questions › 26605983 › difference-between-http-jigsaw-w3-org-css-validator-and-http-www-css-valida

http://jigsaw.w3.org/css-validator/ is hosted by the W3C. It’s the official CSS validator, linked from http://validator.w3.org/.

http://www.css-validator.org/ is not hosted by the W3C (*). It’s misleading because they use the same branding (almost identical site copy, except for additional advertisement/Facebook widget).

They may or may not use the same validator code, as the code is FLOSS.
