Features

• Access your local Harness instance remotely from the web, a PC, or a mobile device: DSH first, with Codex, Cursor, and Antigravity support too.
• DeepSeek Harness Desktop is ready to use after installation, with its native interface and no separate desktop conversation UI.
• Create workspaces, configure models, and switch conversation models with the same smooth workflow as local use.
• No public listening port or public IP is required on the Harness Host. Connect from anywhere with internet access over a bidirectional end-to-end encrypted channel.
• Prefer P2P connections, use TURN relay nodes worldwide, and fall back to multiple Server Relays when needed.
• Access workspace files, read-only previews, remote terminals, and authorized local development-service previews through the native Harness sidebar.
• Remote Tool context injection supports Host and workspace discovery, Harness session creation and management, history reading, waiting for execution, interruption requests, and authorized file transfers. Details.
• Alongside DeepSeek Harness, access native workspaces for Codex, Cursor, Google Antigravity, Pi, OpenCode, Claude Code, Hermes Agent, and other tools through ACP integrations, with remote file browsing and terminals.
• Clients are available across Android, iOS, Web, and native DSH.
• Multiple clients can connect to the same Harness Host simultaneously, with RPC calls and streams isolated per connection.

iOS client

• Join the beta

Quick start

1. Open Remote from the DeepSeek Harness sidebar. 2. Choose Zhihu, GitHub, or Google authorization, or sign in with an account and password. Account registration requires an invitation code; email the repository author to request one. 3. On another device, install the same plugin in DeepSeek Harness and sign in as described in steps 1–2. Alternatively, use Remote Web, iOS, Android, or DSH Go directly without installing a plugin. 4. Select an online Host, then choose an existing workspace or browse remote directories to open one.

By default, Remote uses this project's hosted Server at https://dsh.r2049.cn.

For self-hosting, use the repository's minimal Server. The current version includes P2P coordination and a Relay Server, but does not provide the full hosted Remote Web experience.

Screenshots

Desktop

On another computer, select an online Host and open its workspace. The workspace opens in the native Harness interface, with the active Host and encrypted connection status in the header.

To prevent this computer from controlling other Hosts, open the Host list at https://dsh.r2049.cn/ and enable Controlled only. This device will no longer see other devices under your account, while Web and other clients can still connect to it remotely.

Android

Use text or image prompts, switch models, and access supported workspace files and terminals.

The interface follows the system language and supports English, Simplified and Traditional Chinese, Japanese, Spanish, German, and French. In language settings, tap “More ...” to show all languages. See the Android guide for details.

Mobile Settings includes a global Compact conversations switch, off by default and applied when a conversation is next opened.

Supporting Hosts reduce historical tool details while preserving messages and tool status. Turn the setting off and reopen the conversation to load full history.

How it works

DSH Desktop / Remote Web / Android
  ↔ authenticated, end-to-end encrypted channel
Remote Plugin on the Host
  ↔ supported Harness or optional Codex workspace support
Harness sessions/workspaces or Codex projects

The Harness Host does not need a public listening port. Connect from anywhere with internet access over ds-harness-remote’s bidirectional end-to-end encrypted channel.

The client switches to the selected Host’s native Harness API, keeping the original workspaces, tools, and permission flows on that computer.

Every settings namespace registered by the Host can also be configured remotely through the official Harness settings API, with full support for most plugin settings.

Experimental ACP workspaces

The Host runs local ACP-capable Agents and forwards prompts, streamed replies, and approvals through ds-harness-remote. Each Agent keeps its own workspaces and sessions; only session translation for DSH is performed, without writing to Harness storage.

Supported backends:

• Codex — connected through its independent App Server interface, with the same workspace entry.
• Cursor — connected through the CLI's ACP interface.
• Antigravity (AGY) — its stream-json CLI is adapted to the ACP gateway.
• Pi Agent (experimental) — install @earendil-works/pi-coding-agent and pi-acp on the Host, configure Pi's provider locally; Remote automatically detects and initializes Pi unless explicitly disabled in Remote settings. The workspace is available only after ACP initialization succeeds. Uses the separate ACP data plane. Tools run with Host-user permissions; per-tool confirmation requires a Pi extension and is not enabled by default.
• OpenCode — connected through opencode acp, with workspace discovery and history recovery. Host startup checks the CLI's supported options, accepting both native-listener and stdio-only ACP builds. Native session archiving on Desktop/Android requires the authenticated loopback API; builds without it report archiving unavailable. Archive state is saved by OpenCode; history is retained. Unarchive is not yet exposed.
• Claude — uses a locally authorized claude-agent-acp on the Host; enable it in Remote settings. Desktop/Android support workspaces, history, text prompts and approvals. Image input and direct Files/Terminal access are not available.
• Hermes — runs Nous Research's Hermes Agent through its own ACP server (hermes acp); opt-in in Remote settings. Desktop/Android support workspaces, history, streamed thinking and tool output, text prompts, approvals and model selection. Image input and direct Files/Terminal access are not available.

Setup and adapter development: Agent workspace integration guide.

Model selection for Cursor, Claude, Hermes, Pi, OpenCode, and AGY on Desktop/Android uses the Host's actual model catalog as determined by the Agent’s ACP interface.

Reasoning effort options depend on what the backend provides. Cursor uses a separate process per session, so model changes do not affect other conversations.

End-to-end encryption

Harness business traffic is encrypted on the Client and decrypted only by the selected Host using the fixed Noise_IK_25519_ChaChaPoly_SHA256 suite.

Connections must pass both same-account membership and locally pinned device identity key checks.

The service can coordinate connections and observe necessary network metadata, but it cannot read session messages, prompts, tool output, workspace paths, or remote file contents.

See End-to-end encryption for the handshake, key lifecycle, visible metadata, replay protection, and security limits.

Network and transport

The Host opens outbound connections only; it does not listen on a public port or require router port forwarding.

Remote negotiates paths in the order LAN -> P2P -> TURN -> Relay.

When WebRTC is unavailable or cannot connect, it falls back to the encrypted WebSocket Relay.

Every path carries the same Noise ciphertext and keeps the same Host/Client identity boundary.

See Network and transport for the topology, control and data planes, NAT behavior, fallback, reconnect semantics, and current validation status.

Security

• On LAN and P2P paths, data bypasses the Server except for connection coordination. TURN uses the open-source coturn server; Relay mode forwards traffic over WebSocket.
• Session traffic is end-to-end encrypted. The service relays ciphertext without storing session plaintext or device private keys.
• Server membership and the Host's locally pinned peer identity must both authorize a connection.
• Remote Tools injection — optional remote_* session tools; enabled by default and configurable in detailed Remote settings.
• Interactive terminals use the Host-local terminal.enabled switch (on by default). They run as the Host user, independently of Agent approvals.
• General tool RPC and remote desktop are not exposed.
• The workspace picker lists folders only and returns bounded, read-only directory metadata.
• Remote file preview cannot write, delete, upload, execute, or open a path in an external application.
• Codex Remote / Agent ACP is optional, can be disabled, and follows the same encrypted Host permission boundary as the rest of Remote.
• Removing a device revokes its credentials, membership, and active Remote connections.

FAQ

Do I need a public IP or port forwarding?

No. The Host only opens outbound connections and never listens on a public port.

Can the service read my conversations?

No. The service relays ciphertext only. Routing, authorization, presence and rate limiting require control metadata such as account and device ownership, online status, connection times and connectionId; prompts, conversation content, tool input and output, workspace paths and file preview contents stay unreadable.

Which machine can act as a Host?

Any signed-in Harness instance with the Remote plugin installed can act as a Host, whether on Windows, macOS, Linux, or even DSH Go.

Can several devices connect to one Host at the same time?

There is currently no limit on concurrent client connections, with RPC calls and streams isolated per connection.

Which Harness versions are supported?

The current baseline is dsh-v0.2.1-rc.5, compatible with 0.2.0 rc.2 / rc.1. See the compatibility guide.

Harness 0.1.1-rc.2 ApiProxy support has been removed from the Host plugin, its bundled Remote client, and Android. Use a Host with the official Typert Remote carrier; Hosts that only provide ApiProxy or lack capability discovery are rejected, with no fallback.

CodeX/ACP keep their independent data planes, and Desktop projections use Typert in memory.

Why does the Linux installer require root?

It configures a systemd system service, so the Host, Agent tools and remote terminals run with root privileges. Only expose it to trusted accounts.

Can I install the iOS app directly?

It is in TestFlight beta today and not publicly released; see issue #20.

How is this different from frp, a tunnel, or remote desktop?

Conventional server-based TCP port forwarding routes traffic through a Server, making its bandwidth a potential bottleneck.

This project probes four connection modes in sequence to establish P2P connections even in complex network environments.

Remote desktop captures the entire computer screen and reproduces it on the client, placing demands on upload and download bandwidth as well as computer performance.

This project encrypts and transmits only the messages needed by the native Harness conversation interface. General tool RPC and desktop control are not exposed, and permissions and approvals remain on the Host.

Tailscale, CF Turn, and UU Remote are also excellent solutions; choose whichever fits your needs.
