Psiphon 3

Psiphon Content Delivery Software
Psiphon is a simple to administer and user-friendly, web-based proxy application. It allows users in regions with unrestricted Internet access to provide access to denied content to their friends, family, and associates in regions with restricted access.

Please contact the project leader if you're interested in helping us take Psiphon forward.

NOTE: The Psiphon 1.x and 2.x are different projects with different aims andarchitectures.

 Psiphon 1.x is a light-weight web proxy designed to run on a home PC (MS Windows-based) with no central management component. With Psiphon 1.x, a user asks a friend to run a proxy and can then access blocked sites via his or her friend's Internet connection. The Psiphon 1.x source code is available here: As of September 2010, Psiphon 1.X is no longer officially supported or actively developed by Psiphon inc.

Psiphon 2.x, a centrally managed web proxy system deployed by Psiphon Inc. to provide content delivery services through a cloud-based infrastructure.

What's New in version 2.5
  • Added Propagator Class and removed Node Admin/Node Host. Propagator is associated with multiple proxies and manages Power Users on all associated proxies.
  • Managing Power Users consists of viewing the list of Power Users, including their invite stats; inviting new Power Users; and assigning Power Users to proxies within the set the Propagator manages.
  • Also, when the Admin transitions users, if a Power User is transitioned to a new proxy, his managing Propagators are automatically granted access to the new proxy.
