title: Flask dev server limits
body: <p>I implemented a REST API using flask and I am wondering what is the limit of the dev. server?</p>
  
  <p>I mean why investing time and money to deploy the api on a prod server while the dev. server can support the traffic.</p>
  
  <p>To avoid marking the question as duplicate, I am not asking for security risks, I want to know what are the limits of the flask dev. server in term of request/seconds.</p>
  
  <p>Thanks in advance.  </p>
