title: How to run app on App Engine for free
body: <p>I am trying to run Parse Server, a Node.js app, on Google App Engine. And I am on trial period with $300 free credit.</p>
  
  <p>From this page, <a href="https://cloud.google.com/appengine/docs/quotas" rel="noreferrer">https://cloud.google.com/appengine/docs/quotas</a>, it says there is 28 free instance-hours per day. The app is running with 2 instances and, according to the report, my account is being charged for Compute Engine (G1 Small) for 48 hours everyday.</p>
  
  <p>So how could I benefit from that 28 free hours?</p>
