⚠️ Work in Progress

---

rusbmux is a drop-in replacement for usbmuxd, written in Rust.

It lets you communicate with Apple devices without requiring usbmuxd to be installed or running system-wide.

Why?

usbmuxd must be installed and running as a system daemon to communicate with Apple devices.

That creates friction:

• You can’t easily ship a self-contained binary
• You depend on system services you don’t control
• Cross-platform distribution becomes painful

Sometimes you just want to ship a program that just... works.

What rusbmux does differently

rusbmux removes the daemon dependency while staying compatible with existing tooling:

• Portable
• Can run as a daemon or non-daemon (no sockets)
• Can be Used directly as a library by existing usbmuxd clients
• No separate installation step
• Android support

Roadmap

Core

• Protocol framing (encode/decode usbmux packets)
• Clean error handling
• Logging + debug mode

Device Management

• Track connected devices
• Handle device unplug safely
• Support multiple devices at once

Connection

• Raw USB packet parser
• Per-connection state (sequence numbers, etc.)
• Multiplex multiple connections
• Clean connection shutdown
• Timeout handling

Compatibility

• Support old and new device protocol versions
• Test against multiple iOS versions

Security

• Safe storage of pair records (on disk/on memory)

Performance

• Benchmark
• Reduce memory allocations as much as possible
• Optimize packet parsing/encoding/decoding

Commands

• ListDevices
• Connect
• Listen
• ListListeners
• ReadPairRecord
• ReadBUID
• SavePairRecord
• DeletePairRecord

Lib

• Public Rust API
• An rusbmux provider for idevice
• FFI for other languages

Platforms

• Linux
• macOS
• Android
• FreeBSD
• Windows (not sure about this)

Arch
