What is most valuable?
Deploying with git, npm install git hook ... basically, they got it right for nodejs servers hosting. Free trials is limited (1 app running at a time) but good enough for a proof of concept. Using an Heroku backend and a GithHub pages front end serving static content, I can scale my app for free to a reasonable level.
What needs improvement?
Plugins aren't cheap (Mailchimp is $1.5/1000 emails).
For how long have I used the solution?
How are customer service and technical support?
The doc is good, for nodejs at least. It is newbies friendly.
Which solution did I use previously and why did I switch?
I rejected Google app engine for there lack of nodejs support, and AWS for the complexity of setting up a simple app.
How was the initial setup?
The CLI tools are good and deployment is quick. The web control panel ain't that great, I got into trouble trying to launch my app.
What's my experience with pricing, setup cost, and licensing?
