Psiphon 3 is a free, open-source censorship circumvention tool designed to provide uncensored access to internet content in restrictive environments. Developed by Psiphon Inc., it combines VPN, SSH, and HTTP Proxy technologies to help users bypass digital barriers imposed by governments, corporations, or educational institutions.

: In SSH modes, users can choose to tunnel only international traffic while accessing local websites directly for better performance.

: The client checks for and installs the latest version automatically to stay ahead of new censorship tactics.
