opencode` is a terminal-based AI coding agent for your own machine. But what if "your machine" is the phone in your pocket?
OpenCode Android is a free, MIT-licensed Android launcher that installs opencode natively inside Termux (no root, no proot), runs its local server, and gives you the chat UI as a native app: guided setup, one-tap start, background update checks and notifications.
What it does
-
Guided setup wizard — detects Termux, enables the external-command bridge with a single pasted command, installs the dependencies (glibc runtime included) and configures opencode with
autoupdate=falseso updates stay under your control. -
One-tap chat — starts
opencode serveon127.0.0.1:4096and opens opencode's own web UI in a WebView. A health check and a live status dot show whether the server is up. - Background upgrades with real progress — updates run visibly inside Termux while the app reads the progress markers and shows a live progress bar, then restarts the server automatically.
- Notifications — a daily check tells you when a new opencode version or a new launcher version is available (one notification per version, deduplicated).
- Self-update — the launcher updates itself from its GitHub releases, with an explicit tap.
Requirements
- Android 8.0+ on an arm64 (aarch64) device.
- Termux installed from F-Droid or GitHub (the Play Store build is deprecated and will not work).
- No root. If your phone offers root to the app, deny it — everything works without it.
How it works
The app never bundles the agent. It drives Termux through the official RUN_COMMAND intent channel (you enable allow-external-apps=true once by pasting the one-line command the wizard shows). Installation and upgrades run visibly inside Termux; the launcher only displays progress and talks to the local server the same way your browser would.
Install
- Download the APK from GitHub Releases.
- Open the app and follow the wizard (~2 minutes).
- Start chatting with your agent.
Why this exists
Most mobile clients for coding agents are remote controls: they connect to a server running somewhere else. This one is the opposite — everything runs on the phone. It was built with opencode itself (fittingly) and designed so the whole flow works with as few taps as possible.
