I have a project in django 2.0 nad django-channlels 2.0 which I need to host I followed the documentation and I was able to run channels on localhost along with redis
but when I hosted on pythonanywhere,it showed it doesnot support websocket, so then I hosted on heroku,but there they were asking for verification of credit card info which i dont have to run redis.Are there additional hosting website whre I can rrun redis erver for free

Or is it poosible to implement channels without channel_layer and redis.My code is working perfectly fine on local host but can't host online for free.

class PageConsumer(WebsocketConsumer):
 def connect(self, **kwargs):
 self.accept()
 channel_layer = get_channel_layer()
 async_to_sync(channel_layer.group_send)("admin", "type": "analytics.admin_message", "message": "plus")

 def disconnect(self, close_code):
 channel_layer = get_channel_layer()
 async_to_sync(channel_layer.group_send)("admin", "type": "analytics.admin_message", "message": "minus")

its corresponidng receiver

class ChatConsumer(WebsocketConsumer):
 def connect(self, **kwargs):
 self.accept()
 async_to_sync(self.channel_layer.group_add)("admin", self.channel_name)

 def disconnect(self, close_code):
 async_to_sync(self.channel_layer.group_discard)("admin", self.channel_name)

 def analytics_admin_message(self, something):
 if something["message"] == "plus":
 self.send(text_data=json.dumps(
 'message': "plus"
 ))

 else:
 self.send(text_data=json.dumps(
 'message': "minus"
 ))

 def receive(self, text_data):
 print("data hai bhyi", text_data)
 text_data_json = json.loads(text_data)
 message = text_data_json['message']

 self.send(text_data=json.dumps(
 'message': message
 ))

settings.py

CHANNEL_LAYERS = 
 "default": 
 "BACKEND": "channels_redis.core.RedisChannelLayer",
 "CONFIG": 
 "hosts": [("127.0.0.1", 6379)],
 ,
 ,

from the docs

Channel layers are an entirely optional part of Channels as of version 2.0. If you don’t want to use them, just leave CHANNEL_LAYERS unset, or set it to the empty dict .

It will mean you will be unable to use self.channel_layer in the consumer, which you rely on.

So, it's optional but you need it.

In memory exists:

CHANNEL_LAYERS=
 "default": 
 "BACKEND": "channels.layers.InMemoryChannelLayer"
