Hey HN,
|
||
|
||
I built a React Native / Expo Android app that lets you control a running [opencode](https://github.com/sst/opencode) session from your phone.
|
||
|
||
**What it does**
|
||
|
||
opencode (sst/opencode, MIT) is a terminal-based AI coding agent — you run it on your laptop or a server, it talks to Claude / GPT / Gemini / local models via your own API keys, and it writes, edits, and runs code through tool calls. OpenCode Mobile is a thin HTTP + SSE client that connects to that server process. From your phone you can:
|
||
|
||
- Watch token-by-token streaming output as the agent reasons and codes
|
||
- Review inline file diffs before they're written
|
||
- Approve or reject tool calls (file writes, shell commands) in real time
|
||
- Start, resume, and switch between sessions
|
||
- Connect over local Wi-Fi, Tailscale, Cloudflare Tunnel, or ngrok
|
||
|
||
**Why I built it**
|
||
|
||
I run long opencode sessions that outlast my desk time. I wanted to check in from the couch, approve a tool call, and let the agent keep going. The alternatives — SSH + a terminal app, or generic Claude/GPT chat apps — lose the structured session state: no diffs, no tool-call gating. The opencode HTTP API was already there; the phone just needed a real client.
|
||
|
||
**How it's built**
|
||
|
||
- React Native + Expo SDK 54, TypeScript throughout
|
||
- SSE streaming via an `EventSource` polyfill (RN has no native one); needed patching because Android's OkHttp drops the `Accept: text/event-stream` header across redirects, which breaks reconnects
|
||
- Diff rendering with a custom line-level parser into a FlatList — no WebView, so dark-mode theming stays consistent and it's cheap to render
|
||
- Biometric auth via `expo-local-authentication` gates app-open and individual sends
|
||
- Connection secrets in the Android Keystore via `expo-secure-store`
|
||
- CI builds a signed AAB on every tag via GitHub Actions + EAS
|
||
|
||
**What it is not**
|
||
|
||
Not a standalone AI model and not a code editor. You need a running opencode server. If you already use opencode, setup is:
|
||
|
||
```
|
||
npm install -g opencode-ai
|
||
OPENCODE_SERVER_PASSWORD=yourpassword opencode serve --hostname 0.0.0.0 --port 4096
|
||
```
|
||
|
||
…then paste the URL into the app. Your API keys stay on your server; nothing proxies through any backend of mine.
|
||
|
||

Happy to answer questions about the SSE streaming implementation, the Expo build pipeline, or the opencode API surface.
