3 cents per hour per instance instance after the first. With this space heating up so much, how do you compete with competitors offering free apps at the entry level. Sure, maybe you pick up better clients, but the other model still give you more prospects.<p>Either way, it's nice to be able to create dev / staging / experimental instances which aren't costing 3 cents per hour. I could host these on my own VPS and use Duostack for production only, but I'm more likely to use Heroku for the full stack.<p>Edit: The first app is free, but my point is still valid.
