About this app

Welcome to the Warren VPN client app source code repository.

Warren VPN is a fork of the Mullvad VPN app (GPL-3.0, Mullvad VPN AB). This repository preserves the complete upstream git history, back to 2016, with original authorship intact. It is standalone rather than a GitHub-native fork: the project started in a private repository, GitHub does not allow a private fork of a public repository, and a repository cannot join a fork network after creation. The upstream remote stays wired: security and correctness fixes in the platform layers (routing, DNS, firewall, split tunneling, leak checker) are cherry-picked from upstream, per docs/UPSTREAM-DETACH.md.

Warren VPN carries traffic over a QUIC tunnel and identifies its users by a non-custodial wallet. One Ed25519 key, derived from a BIP39 mnemonic that never leaves the device, authenticates the tunnel's TLS handshake to the exit and signs every request to the Warren backend, which serves accounts, subscriptions and devices. There is no account number and no bearer token. The backend host follows the build channel (api.beta.warrenbrowse.com for the beta builds shipped today).

What's new

v1.1.54Oct 26, 2026

Fixed
[Windows, macOS, Linux] Announce the forwarded port, and write it into the linked torrent client, when the app opens after the VPN already got it, as it does when the computer starts. Both used to wait for the next change of port, usually a change of country. [Windows, macOS, Linux] Give the forwarded port back to the server when changing country, so the next country grants the same port at the first request instead of refusing it first, and coming back to the previous country gets it back at once. [Windows, macOS, Linux, Android] Ask again at once when a server refuses a port entitlement, instead of two seconds later.
