pip install anymesh==0.4.0



AnyMesh is a multi-platform, decentralized, auto-discovery, auto-connect mesh networking API.

Current supported platforms:

  • Node.js
  • iOS
  • Python

AnyMesh makes it easy to build a decentralized, multi-platform mesh network on any LAN, without having to manually implement TCP / UDP processes.

All supported platforms work roughly the same way. Configure each AnyMesh instance with 2 properties:

  • Name - a name or identifier for the instance
  • Subscriptions - an array of keywords for your instance to listen for

AnyMesh will automatically find and connect to other AnyMesh instances.

Then, to communicate across the network, an instance can send two types of messages:

  • Request - send a message to a specific device Name.
  • Publish - send a message associated with a keyword. Any other instance that subscribes to the keyword will receive the message.

That's all there is to it!


Q: So what is AnyMesh?

A: AnyMesh is a convenient, powerful way to get multiple programs to connect and send information to one another. Each instance of AnyMesh will automatically find and connect to other instances. AnyMesh instances can be running within the same app, on separate apps on the same device, or on different devices within the same local network (LAN).

A network can contain any combination of these relationships, across any languages or platforms - You may have a Mac OSX desktop computer running 2 instances of AnyMesh-Python alongside 1 instance of AnyMesh-Node. These instances are also connected to 2 more instances of AnyMesh-Node on a Linux computer down the hall, and a Raspberry Pi running AnyMesh-Python hardwired into the router. Launch an app on your iPhone that uses AnyMesh-iOS, and instantly connect to all these devices automatically!

Q: Why use AnyMesh instead of RabbitMQ, 0MQ, etc?

A: AnyMesh is certainly not the first mesh networking API on the block. But AnyMesh was created with a few unique purposes in mind that sets it apart from other libraries:

  • AnyMesh is truly decentralized - Even at the lowest levels of the TCP connections, there is NO device acting as any kind of server or relay. All AnyMesh instances manage their own connections to every other device. This means any device can enter or leave the mesh at any time with ZERO disruption to any other connections.
  • AnyMesh has EXTREMELY minimal setup and configuration - Just name your instance and optionally give it some keywords to subscribe to. There is no need to define roles for instances - Every instance uses the same simple message distribution pattern.
  • AnyMesh is multi-platform - We currently support iOS, Python, and Node. We hope to start work on Java/Android very soon.

Q: How can I help?

A: AnyMesh is still very young concept, and although it is fully functional, it will be a little while until we reach v.1.0 on all supported platforms. See the file for suggestions on contributing to development. #AnyMesh Python

Please Read:

11/4/2014 - 0.4.0 has been released! See CHANGELOG for details.

AnyMesh Python uses the venerable Twisted library to handle asynchronous networking processes.
Download and install Twisted here:

##Installation pip install anymesh

##Quickstart: Create an AnyMesh Object:

any_mesh = AnyMesh('Dave', ['status', 'alerts'], delegate)

The "delegate" variable in the constructor above should be a subclass of AnyMeshDelegateProtocol. Here's an example:

class AmDelegate(AnyMeshDelegateProtocol)
  def connected_to(self, anymesh, device_info):
    print "connected to " +
    for subscription in device_info.subscriptions:
      print subscription

  def disconnected_from(self, anymesh, name):
    print "disconnected from " + name

  def received_msg(self, anymesh, message):
    print "received message from " + message.sender
    print "message: " + json.dumps(

Start the Twisted Event Loop:;

Send a request:

any_mesh.request("Bob", {"msg":"Hello Bob", "priority":1})

Publish to subscribers:

any_mesh.publish("updates", {"update":"new headlines!", "content":[1, 5, 8]})

A few more helpful methods:

Get info on current connections:

var connectionsList = any_mesh.get_connections()

Change your anymesh instance's subscriptions:

any_mesh.update_subscriptions(['weather', 'sports'])

Define a callback in your delegate to be notified of another anymesh's subscription change:

def received_updated_subscriptions(self, anymesh, subscriptions, name):
	print name + "updated their subscriptions!"
	for subscription in subscriptions:
      print subscription	

Some notes on Twisted:

AnyMesh Python uses Twisted's Reactor run loop. If your app needs to integrate its own event loops, you have a couple of options:

If possible, I would recommend the former, as long as your tasks do not block the event loop for too long.
