After installing, sign in with your Fexyn account. The 7-day free trial starts when you create the account, not when you install the app. Create one if you don't have one yet.
Windows app available now in Beta. Full public release expected early 2027.
Auto updates
Updates ship through a dual-verified pipeline — Ed25519-signed manifest plus Authenticode signature on the binary. The app checks both before installing anything.
Three protocols
WireGuard, VLESS Reality/XRay, and OpenVPN all ship in the same installer. The app picks one and rotates if a protocol is blocked on your network.
What's in the installer
- User-facing appThe Fexyn VPN app you sign in to and click Connect from.
- SYSTEM-level helper serviceA separate service that owns tunnel creation, routing, and firewall rules — so the UI doesn't need admin rights for every connect.
- Wintun driverThe signed Wintun TUN driver used for the WireGuard data path.
- Protocol enginesWireGuard (boringtun), XRay-core for VLESS Reality, and an OpenVPN engine for the compatibility fallback.
