Psiphon is a user-friendly, simple to administer circumvention system. Our aim is simplicity. Psiphon strives for a zero footprint architecture that can be scaled from a home user serving a few friends, to a cloud-based infrastructure serving thousands. Psiphon source code is yours to develop and build on. Psiphon inc is the maintainer of the code base, and the operator of Psiphon's commercial cloud-based services and solutions.
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: https:/
Psiphon 2.x is centrally managed web proxy system deployed by Psiphon Inc. to provide content delivery services through a cloud-based infrastructure. It's designed for larger scale implementations and requires more skills to set up and operate than 1.0. Psiphon 2.X is a link rewriting proxy and therefore suffers from some compatibility with web 2.0 sites.
PsiphonX - is designed to overcome the shortcomings of link-rewriting proxies which made it difficult and cumbersome to view web 2.0 sites like YouTube and Facebook. PsiphonX runs from a single executable file which configures the Internet proxy settings of a machine to point HTTP traffic to a local proxy that then forwards the traffic to a Psiphon in-proxy via a secure connection (via an SSH Tunnel). When the user quits PsiphonX, the original Internet configuration is reset.
We are also planning on relaunching Psiphon 1.X as a new product code-named "Swarm". The objective is to develop a version of Psiphon that can be loaded onto a plug computer and managed through a simple user GUI.
