Cypress testing framework that runs in the browser

I was just testing this piece of software and i'm really impressed by what these guys accomplished.

It runs tests on file save and let's you open the developer tools. When it rans on the cli it even records a video for you so you can playback to see what went wrong.

I had seen something similar to this with chimp, still had some issues that cypress solves, by being interactive in every step of the way.

Sorry it looks like I'm trying to sell this, I'm not, I don't know the company, I'm just impressed.
