Validator.nu

Validator.nu is an HTML5 conformance checker. Its syntax schemas, checker (/whattf/syntax/, org.whattf.checker) and build tooling were developed in repositories hosted here. It is now maintained as the Nu HTML Checker.

This page is original documentation. Validator.nu is the work of its own authors/community; VersionDude has no authorship or affiliation. The Subversion repository once hosted at svn.versiondude.net is no longer online — use the current home below.
