Does anyone know of a tool webmasters can use to check scripts they intend to deploy on their website, to see if they load scripts from any third-party domains?

I know they can use #NoScript to retrospectively check once the site is on a test server. But it would be even better if they could check scripts while they're deciding whether or not to spend time incorporating them into their site design.
