What is Twisted?

Twisted is an event-driven networking engine written in Python and licensed under the open source MIT license.

Easy Custom Servers and Clients

Twisted makes it easy to implement custom network applications, both servers and clients. Here's a TCP server that echoes back everything that's written to it:

from twisted.internet import protocol, reactor

class Echo(protocol.Protocol):
    def dataReceived(self, data):
        self.transport.write(data)

class EchoFactory(protocol.Factory):
    def buildProtocol(self, addr):
        return Echo()

reactor.listenTCP(1234, EchoFactory())
reactor.run()

Learn more about writing servers, writing clients and the core networking libraries , including support for SSL, UDP, scheduled events, unit testing infrastructure, and much more.

Event-Driven Web Applications

Twisted includes an event-driven web server. Here's a sample web application:

from twisted.web import server, resource
from twisted.internet import reactor

class HelloResource(resource.Resource):
    isLeaf = True
    numberRequests = 0
    
    def render_GET(self, request):
        self.numberRequests += 1
        request.setHeader("content-type", "text/plain")
        return "I am request #" + str(self.numberRequests) + "\n"

reactor.listenTCP(8080, server.Site(HelloResource()))
reactor.run()

And Other Protocols

Twisted also supports many common network protocols, including SMTP, POP3, IMAP, SSHv2, and DNS. For more information see our documentation and API reference.
