Yellow Lab Tools runs on a Node.js server, is easy to install, and lets developers test a website (via an URL). This is done by accessing the website via PhantomJS and collecting various metrics and statistics.

These metrics are then manipulated and presented in an easy to understand manner, organized in categories of interest.

Currently there's a section for analyzing the JavaScript execution timeline, complete with a JavaScript profiler that lets developers see how JS scripts have been executed, what where their results and how it impacted the page performance.

The JS scripts and their results are categorized based on how they interact with the DOM while it's being created, interacted with, loading new content and after it's has been completed.

The second main utility is a grading feature that provides A-to-F grades based on the performance of various utilities and operations like DOM complexity, DOM manipulation, the number of HTTP requests, network interactions, CSS complexity, and so on.

Besides the Web-based version of Yellow Lab Tools, the package also comes with Node.js CLI integration, a Grunt task, and a publicly accessible RESTful API.

All in all, Yellow Lab Tools can be really useful for both beginner and advanced coders, helping them improve or fix the way they write JS and CSS, boosting page loading speeds and their code's overall performance.
