A socks5 proxy with ssl support

Project description

Furion is an encrypted proxy written in Python. In essence, it’s just socks5 server with ssl support. It’s often used with upstream Furion servers to avoid censorship.

Project is hosted at GitHub, mirrored on BitBucket.


  • Automatic upstream fail over (when multiple upstream servers are available).
  • Built-in latency check for choosing the fastest upstream.
  • Periodical upstream updates from a designated central registry.
  • Builtin DNS server/proxy to avoid poisoning.
  • Limit what ports that clients are allowed to connect to.
  • Easy account management on the server side.


Furion has no external dependencies other than a standard Python 2.x (>=2.6) installation. Python 3.x is supported. There is optional support for gevent, which would be used if an existing gevent installation was discovered.


Furion can be installed via pip:

pip install furion

or setuptools:

easy_install furion

To start using Furion, you need at least a furion.cfg file.

By default, Furion will look for furion.cfg and upstream.json in /etc/furion or the current working directory. You can specify path to the configuration file after a -c switch.

For client, an upstream.json file is also needed for upstream checking to work. Alternatively, you can put the upstream.json file somewhere accessible via http, so that you can share that address with your friends. Then configure the upstream section of your furion.cfg file like below, to use that upstream file.


central_url = http://your.upstream.json

autoupdate_upstream_list = on

update_frequency = start

upstream_list_path = upstream.json

Read configuration files in examples directory for more information.

Client For Windows

There is a win32 binary available for download with every release.

If you want to build yourself, a python installation must be present, personally I used ActivePython. Then install pyinstaller to C:\pyinstaller and use pyinstaller.bat to build.
