Mobile remote access

Access Harness on your computer from a phone browser or DSH Mobile over LAN or a public tunnel.

Your phone accesses Harness on the computer; it does not run the core or tools locally. Keep the computer awake, the Harness service running, and any required tunnel online.

Connect to your computer

Open Share at the top of the desktop and choose a connection method:

LAN

Connect the phone and computer to the same trusted network, select Enable LAN sharing, then scan the QR code or open the link on your phone.

Public tunnel

Select Enable tunnel, wait for it to become ready, then scan the QR code or open the link. The devices do not need to share a network.

Enter the temporary pairing code shown on the desktop if prompted, then confirm that the computer’s sessions appear. For failed LAN connections, check the firewall and Wi-Fi client isolation; do not use 127.0.0.1 or localhost.

Remote-access settings

Select the gear in the top-right corner of the Share panel, or open Harness Settings → Remote access → Remote access tab.

Setting	Purpose
LAN / Listen address	Toggle LAN sharing and prefer the recommended address. Choose all interfaces for changing addresses or multiple adapters
Public tunnel	Quick assigns a random domain without an account. Named mode requires a Tunnel Token, public hostname, and route configured in Cloudflare. Check its status and start or stop it as needed
Access control	Get a temporary pairing code, generate a permanent access code, or revoke all paired access

Temporary pairing codes last 5 minutes and rotate after use; paired devices remember authorization long-term. Disabling sharing, stopping a tunnel, or rotating the permanent access code does not revoke issued sessions. Use Revoke paired access to clear all device grants, sessions, and access codes.

Enabling sharing through the interface enables authentication. Remote access is not read-only: it provides the computer’s sessions, tools, and granted permissions. Authorize only trusted devices, protect links, QR codes, access codes, and Tunnel Tokens, and never expose an unauthenticated service.

Use DSH Mobile

Get the Android APK or join iOS TestFlight from Installation and downloads; unsigned IPAs require your own signing. The app supports Scan LAN automatically, Scan QR code, and recent connections. Scanning requires camera permission; use a tunnel QR code outside the LAN.

Once connected, swipe left to view connection details. Long-press a recent connection to rename or delete it; deleting the record does not revoke authorization on the computer.
