\o/ thanks for sharing the sneak peek. I am one of the developers...
We are slowly going into an alpha phase. A lot of testing and learning is still needed and we would love to hear your thoughts and feedback. 

The current alpha version can be downloaded from GitHub (still needs to be manually installed, but we will be in the browser stores soon)

Let me know if you need help.
