The tool is based on the fabulous Phantomas by Maciej Brencz, that loads a page and collects many web performance metrics. I rewrote some modules to deeper analyse Javascript interactions with the DOM (especially with jQuery). And then it is wrapped inside a small server (inspired by my favorite tool: WebPageTest).

There are so many things left to do, your help would be greatly appreciated! Please report bugs, ask for evolutions and come code with me.
