What is OpenCode Mobile?

OpenCode Mobile is a thin Android client for the OpenCode AI coding agent, built with React Native and Expo. It is not a standalone agent — it connects to an OpenCode server that you run yourself (on your laptop, a VPS, or anywhere you control) and speaks its HTTP + SSE API to browse sessions, stream responses, and review file changes.

All AI model calls happen on your server using your own API keys. The app never proxies your code or conversations through anyone else's servers. It is free and open-source under the MIT license — no feature gate, no ads, and no analytics you did not opt into.

Requirements

You need your own OpenCode server. OpenCode Mobile is a client, not a hosted service. Before it is useful you must run an OpenCode server somewhere you control and make it reachable from your phone.

  1. Install and run OpenCode on your machine:
    npm install -g opencode
OPENCODE_SERVER_PASSWORD=yourpassword opencode serve --hostname 0.0.0.0 --port 4096
  2. Make it reachable from your phone — the simplest secure option is Tailscale (connect to your machine's Tailscale IP, e.g. http://100.x.x.x:4096). A Cloudflare Tunnel, ngrok, or the same local network also work.
  3. In the app, tap Add Connection, enter your server URL and password, and connect.

You bring your own AI provider keys (OpenAI, Anthropic, Gemini, etc.) on the server — your keys, your bill.
