Amazon Web Services free tier, elastic beanstalk running node.js, S3 for static files and stuff or basic web page hosting

or

Google Cloud free tier, Google App Engine running node.js, google cloud storage for static files and stuff or basic web page hosting

both are git-compatible and deployments are as easy as : "eb deploy" or "gcloud app deploy"

for front end stuff, if its just a prototype i just copy a bootstrap 'live preview' design that i like, and jquery stuff together.
