title: Django channels without redis
body: <p>I have a django app based on <a href="https://channels.readthedocs.io/en/latest/tutorial/part_1.html" rel="nofollow noreferrer">this tutorial</a> that works perfectly. It uses Redis in the Channel layers</p>
  <pre><code> CHANNEL_LAYERS = {
      'default': {
         'BACKEND': 'channels_redis.core.RedisChannelLayer',
          'CONFIG': {
              &quot;hosts&quot;: [('127.0.0.1', 6379)],
       },
   },
  </code></pre>
  <p>}</p>
  <p>The problem I have is that my web hosting provider will not allow Redis (unless I pay ££££).</p>
  <p>Every example that I can find uses Redis in this role. Is there an alternative I could use?</p>
