LMVTFY を利用している企業
LMVTFY is a service that watches for new issues and new issue comments on a given GitHub repository. If the comments contain (links to) live Web examples (e.g. a jsFiddle), the example's HTML is extracted and run thru the HTML5 validator. If there are any validation errors, LMVTFY then posts a comment (such as this one) on the issue pointing out these errors, so that the poster may correct them and/or realize the error of their ways.
