What is the tech stack on which WIP is made?

Judging from the source code, I'd say Ruby on Rails (possibly hosted on Heroku).

Nice, my Chrome extension "Whatruns" was giving me Erlang so I wanted to know if that's the case. Thanks. Website is super fast & super slick though.

@marckohlbrugge, are you using a style library on top of neat, or is it you own style you created and reuse for betalist and wip chat?

@marcantoinefon I just write my html/css (or haml/sass to be specific) as I go along. Any design similarities between WIP and BetaList are just my unoriginality in design choices haha. Not reusing any stylesheets.
