Free dynos shutdown every hour when it's not active.Starting up can take next to 10 seconds.Furthermore it's a free service,I don't think people should abuse their generous offer meant for testing purpose. There is no guarantee they will continue offering free dynos forever.

Some people got burned recently hosting mongodb servers on a popular Saas that used to provide free mongodb hosting.Now that Saas is paid only,and though they aren't deleting existing test dbs,they could choose to do it at anytime.

One shouldn't consider free offers fit for any production purpose.

Like you wouldn't use free domains for a production app would you ?

I don't think it's just meant for testing. They choose to make the first dyno free so people will build on their platform. I have a couple of low traffic production apps that run fine at one dyno. If these apps ever get more traffic then maybe I'll scale them up and Heroku will get some money. I think that's the deal that Heroku is offering. I don't think I'm abusing their "generous offer". It's just business, from both sides.
