JSHintr is a web tool that allows you to set your own code standards, easily review a file against these standards, and share the output with other developers. It leverages the power of JSHint:
One barrier to people running jshint is that it's a pain to constantly be copy/pasting code to a textbox to run checks, or to be dropping to a command line. This app aims to help lower this wall, all you have to do is change the URL in your browser from ".js" to ".jshint" and you get pretty output.
If you disagree with a certain issue jshint has raised, you can mark it as skipped. Every issue raised is provided with a code sample with context that expands on hover, even marking the specific characters that were problematic.
You can also clone the project with Git by running:
$ git clone git://github.com/rixth/jshintr
