Ways to use DeepSeek Harness from your phone
Option 1
DeepSeek Harness Web UI
How it works The official npx @deepseek-ai/dsh web command starts a local Web UI on 127.0.0.1:3080. To reach it from a phone, place it behind a private network or authenticated tunnel rather than exposing the local service directly to the internet.
Trade-off You must configure and secure the network path yourself, and the browser experience is not a native mobile control surface.
Best for Developers who want DeepSeek Harness’s own Web UI and already operate private remote access.

Remote desktop access
How it works Open the computer running the DeepSeek Harness Web UI through remote desktop software. The agent and repository stay in the existing environment, but the full desktop is scaled down to a phone.
Trade-off The desktop viewport and pointer model make short mobile check-ins feel heavier than a phone-first interface.
Best for Occasional access when you need the whole development desktop.

A cloud development machine
How it works Run DeepSeek Harness on a hosted machine and reach its environment from your phone. The session can remain online without your laptop, while your repository, provider configuration, and execution environment move to infrastructure you manage.
Trade-off Hosted execution introduces separate cost, access-control, and data-handling decisions.
Best for Developers who intentionally keep their coding environment in the cloud.

Sesori
How it works Sesori installs a pinned DeepSeek ACP adapter on supported Bridges and keeps DeepSeek Harness provider setup and credentials on your computer. The native iOS or Android app can follow the session, review changes, and continue the same local workflow.
Trade-off Your computer must stay on, and DeepSeek Harness permissions and provider data paths remain separate from Sesori’s encrypted phone-to-Bridge channel.
Best for Developers who want DeepSeek in the same phone-first workflow as their other local coding assistants.
