CLOG [1] seems to do something similar (though it's hard to tell; Seed's README isn't terribly informative), except CLOG has more tutorials, is better documented, has a more fleshed out README, and has ongoing support.

This project, which seems interesting, would greatly benefit from a better explanation of what it is, and some screenshots.

Project is not active, but if someone likes it, consider removing node in favour of CLOG. So much easier & faster.

Sooooo. if it runs in the browser why isn't it embedded in the README?
