Horcrux Backup vs Tether

Horcrux is an app for backup and recovery of sensitive data like digital wills, passwords, and cryptographic keys. Rather than backing the data up to the cloud, Horcrux uses advanced cryptography to distribute the data to the devices of the people you choose. All data is encrypted and can only be decrypted when most or all of these people provide their consent. The result is a virtual vault that no single person or key can open.

Tether is an app designed for Linux users running custom desktop environments (Wayland). It provides essential ecosystem integration between your mobile device and your workstation, operating entirely over your local Wi-Fi. There are no cloud servers, third-party services, or accounts required. All data is routed strictly on your local network and secured with end-to-end mTLS encryption. Features: • Shared Clipboard: Sync clipboard text bi-directionally between your iPhone and your Linux machine. • File Transfers: Send documents, photos, and archives directly to your desktop, or receive files from it. • Local Discovery: Uses mDNS/Bonjour to automatically find your desktop - no static IP configuration needed. • Encrypted Connections: Device pairing and all network traffic are secured via mutual TLS certificates. Note: Tether is the iOS client app. To use it, simply run the free, open-source Tether desktop application (available as a CLI or GTK app) on your Linux machine.
