MARZ VPN
Open-source VPN client for Android, Windows and Linux
Open-source MARZ VPN client apps for Android, Windows and Linux: one-tap connect, servers in the US, Sweden and Russia (VLESS with REALITY), sign-in with Telegram or email, plan and traffic shown in the app. English, Russian, Persian and Simplified Chinese.
Windows and Linux apps include a Kill Switch (on by default, can be turned off in Settings) and DNS protection. The Android app has no Kill Switch of its own; use Android's "Always-on VPN" and "Block connections without VPN".
The apps are free and GPL-3.0-or-later licensed. Connecting requires a MARZ VPN account with a trial or paid plan. The free trial starts only when you activate it in the Telegram bot and lasts up to 72 hours or 3 GiB, whichever comes first. ...
