This fork makes the existing opencode run natively on Android: the phone runs the real server, the agent, sessions and the packages/app web UI, served over loopback in a WebView. The Android host adds mobile styles, a read-only Files browser and a Usage panel without modifying the packages/app source. No PC, Termux, root or remote OpenCode server is required; cloud models still need a network connection and provider credentials.
What we added on top of upstream (everything else is upstream opencode):
| Path | Contents |
|---|---|
packages/android |
Android host: Gradle project, WebView activity, embedded server manager, mobile UI adaptations |
script/android |
Reproducible build: build-apk.sh plus helpers for the server, ripgrep, git runtime and translations |
docs/android |
Engineering docs: build, execution policy, native dependencies, upstream patches |
Only five upstream files are modified (Android build target plus runtime compatibility); each change is documented with its reason in docs/android/UPSTREAM_PATCHES.md.
How it works: the Android activity starts the bundled server (libopencode.so serve --hostname=127.0.0.1) on a port selected at startup and loads http://127.0.0.1:<port>/ in a WebView. Tools run from the app's native library directory: /system/bin/sh, bundled git, rg, and a Bun runtime exposed as bun/node.
- Download: releases (
app-release.apk, arm64, Android 8.0+) - Build:
./script/android/build-apk.sh— seedocs/android/BUILD.md - First launch: grant all-files access for persistent data under
/sdcard/OpenCode/home, then Settings → Providers → connect a provider and add a project (~/workspace). Without that permission, data is in app-private storage and is removed on uninstall. WebView project selection may need to be restored after reinstall. - Works: server and web UI, sessions, git with syntax-highlighted diffs (Changes), project file browser (Files), context-usage panel (Usage), command and JS/TS execution
- Limitations: no PTY terminal, no LSP or formatters, no local MCP processes; the native file-watcher binding is unavailable (search uses
rg) - License: MIT, same as upstream
Important
The v0.1.1 release tag points to an older upstream commit without the Android module. The Android source is on main; use that branch for the build instructions. The release APK has not been verified as a byte-for-byte build of main.

OpenCode is also available as a desktop application. Download directly from the releases page or opencode.ai/download.

OpenCode also runs on Android as a native APK built from this fork. The app bundles the real server and the same web UI; with all-files access, server data lives under /sdcard/OpenCode/home and survives app removal. Without it, data is kept in app-private storage and is removed on uninstall.

# macOS (Homebrew)
brew install --cask opencode-desktop
# Windows (Scoop)
scoop bucket add extras; scoop install extras/opencode-desktopThe install script respects the following priority order for the installation path:
$OPENCODE_INSTALL_DIR- Custom installation directory$XDG_BIN_DIR- XDG Base Directory Specification compliant path$HOME/bin- Standard user binary directory (if it exists or can be created)$HOME/.opencode/bin- Default fallback
# Examples
OPENCODE_INSTALL_DIR=/usr/local/bin curl -fsSL https://opencode.ai/install | bash
XDG_BIN_DIR=$HOME/.local/bin curl -fsSL https://opencode.ai/install | bashOpenCode includes two built-in agents you can switch between with the Tab key.
- build - Default, full-access agent for development work
- plan - Read-only agent for analysis and code exploration
- Denies file edits by default
- Asks permission before running bash commands
- Ideal for exploring unfamiliar codebases or planning changes
Also included is a general subagent for complex searches and multistep tasks.
This is used internally and can be invoked using @general in messages.
