DSH Tether carries the DeepSeek Harness web interface to your phone over a direct peer-to-peer connection. The agent keeps running on the machine your code lives on, and the phone gets DSH's own full interface — conversations, tool calls, approvals and settings, not a reimplementation of them. Pair once with a 6-digit code; after that the two ends find each other whatever network they are on.

The case it solves

You are not on your machine's network, and you do not want a server in the middle.

Reaching your own dev machine from a phone usually asks for one of two things: both ends on the same LAN, or a relay you deploy, configure and trust. This asks for neither. The two ends hole-punch to each other through iroh, and once they do, nothing passes through a third party; the fallback relay only ever carries ciphertext it cannot read.

If you only use your phone on the same Wi-Fi as your machine, you don't need any of this — a LAN setup is simpler.

Download and install

Where	Download	How
Machine	—	dsh plugin --profile web add dsh-plugin-tether
Phone	dsh-tether-<version>-arm64.apk from the Release	Signed — install it directly
Phone (iOS)	dsh-tether-<version>-ios-unsigned.ipa from the Release	Beta, unsigned — sign it yourself

The plugin carries a small Rust sidecar that owns the iroh connection, shipped as one package per platform; installing pulls only the one matching your system, with nothing to choose.

The phone build is split by CPU architecture. Any Android phone from the last decade takes arm64; arm is for 32-bit legacy devices, and x86 / x86_64 are for emulators and ChromeOS. Picking the wrong one simply gets refused at install time.

The iOS build is beta: this project has no Mac, so the package is only ever built in CI and has never run on a real device. You sign it yourself with AltStore, Sideloadly or similar (a free Apple ID expires after 7 days). Please open an issue if you hit anything.

You can also build the sidecar from source (needs Rust):

git clone https://github.com/zexadev/dsh-tether && cd dsh-tether
cargo build --release -p tether-host
dsh plugin --profile web add .

Pair

Start dsh web as you normally would, then click Connect phone at the bottom of the sidebar. You get one line to copy:

On the phone, open DSH Tether → Add computer → paste that whole line → name the computer → connect.

From then on the app connects by itself when you open it.
