RudelLinkYour home network. From anywhere.
RudelLink sets up its own WireGuard tunnel to your FRITZ!Box and opens the web interfaces of your devices, from the NAS and the printer to your smart home. One tap is enough; the app fills in the login.

Into your home network in three steps
Your FRITZ!Box address only leads to the router. To reach the devices behind it from outside you need a VPN tunnel, and RudelLink sets it up itself. No extra VPN app required.
Set up WireGuard on the FRITZ!Box
In the FRITZ!Box user interface, create a connection under Internet → Permit Access → VPN (WireGuard). The simplified setup then shows a QR code.
Scan the QR code
Scan the code in RudelLink, or pick the
.conffile or paste it by hand. The key is stored encrypted on your phone.Tap a device
Connect the tunnel, pick a device from the list, and its web interface opens in the app, signed in if you like.
What RudelLink does
Built-in WireGuard tunnel
The app connects and disconnects the tunnel itself and always shows its status at the top of the home screen.
All devices in one place
NAS, printer, cameras, smart home: each with name, address and port, optionally full screen and with a fixed orientation. Drag to change the order.
Automatic login
If a device asks for user and password via HTTP authentication, the app fills both in.
Setup via QR code
Scan the FRITZ!Box QR code or pick the configuration file, done.
Tunnel when you need it
On your home Wi-Fi it goes direct; on mobile data RudelLink connects the tunnel without asking and disconnects it afterwards. Optionally as Android’s always-on VPN, with your own DNS servers and excluded apps. You can also disconnect from the notification.
App lock with fingerprint
Optionally the app asks for fingerprint, face or screen lock on start.
Self-signed certificates
Many home devices use self-signed HTTPS certificates. You can allow them per device.
Export and import
Back up the device list or move it to a new phone, deliberately without passwords or VPN keys.
Honest warning
If the tunnel is off, the app tells you before opening a device and offers to connect right away.
Your credentials stay on your phone
RudelLink only talks to your FRITZ!Box and your own devices. There is no server, no account and no advertising. App privacy policy
Stored encrypted
Passwords and the WireGuard key are stored encrypted in the Android Keystore.
No port forwarding
Your devices stay inside your home network, reachable only through the tunnel you set up.
No account, no cloud
The app signs in nowhere and sends no data to me or to third parties.
Export without secrets
The backup file contains names and addresses only. Passwords and keys never leave the device.

FAQ
Are there ads?
No. RudelLink contains no ads and no trackers.
Do I need the tunnel at home?
No. On your own Wi-Fi you reach the devices directly. You only need the tunnel when you are away. If you save your Wi-Fi as the home network, RudelLink does not even ask about the tunnel at home. For this the app needs location access once – only because Android does not reveal the Wi-Fi name otherwise.
Does the tunnel stay up when I close the app?
Yes, like any VPN app. Disconnect in the app or with “Disconnect” in the notification.
Is RudelLink an app by FRITZ!?
No. RudelLink is an independent project with no affiliation to FRITZ! GmbH (formerly AVM).
Does it work with other routers?
The app is made for the FRITZ!Box. Technically any WireGuard configuration you have as a file or QR code will do.
