title: Deploy Sinatra app on Heroku
body: <p>I have simple Sinatra app.</p>
  
  <p><strong>web.rb:</strong></p>
  
  <pre><code>require 'sinatra'
  
  get '/' do 
      "Hello" 
  end
  </code></pre>
  
  <p><strong>Gemfile:*</strong></p>
  
  <pre><code>source :rubygems
  
  gem 'sinatra', '1.1.0'
  gem 'thin', '1.2.7'
  </code></pre>
  
  <p><strong>config.ru:</strong></p>
  
  <pre><code>require './web'
  run Sinatra::Application
  </code></pre>
  
  <p>But when I deploy my app on Heroku I'll get the error on logs:</p>
  
  <pre><code>2012-03-27T19:17:48+00:00 heroku[router]: Error H14 (No web processes running) -&gt; GET furious-waterfall-6586.herokuapp.com/ dyno= queue= wait= service= status=503 bytes=
  </code></pre>
  
  <p>How can I fix it?</p>
