Bitmask
Bitmask is an open-source VPN client built around provider choice instead of a single network. It can be used with a compatible service or with a server you run yourself, with little setup.
Updated:December 22, 2025
Overview
Bitmask is mainly used by people who want a VPN app they can inspect and trust. The code is open, and the app is designed to avoid tracking and ads.
A key difference is how you connect. You pick a compatible provider, or you point it at your own setup, instead of choosing from a fixed in-app server list.
The interface aims to keep configuration simple. In many cases, it handles the connection details for you, so you can get online quickly.
For privacy and connectivity, it focuses on encrypted tunnels using OpenVPN. It also supports encrypted email in the same project, for users who want both tools together.
