So this might be an aside, but given all the complaints about how expensive Heroku is (despite the free tier, how they handle everything below the app, it's the gold standard in PaaS) has anyone tried out competitive services like Cloud Foundry [1], OpenShift [2] or Cloud66 [3]? Cloud Foundry and OpenShift are either hosted with similar free tiers or you can set up yourself, and Cloud66 is more for the DIY crowd being free for development environments. I do appreciate Heroku's free tier for toy projects but if you had to scale on a budget (and could handle the setup) don't know if that'd be a better starting point than the other options.
