r/selfhosted — copy-paste ready

Subreddit: r/selfhosted (~400k+ members) Flair: Release (use Release for an app launch; if not available, use Product Announcement). Rules that matter here: Self-promotion is allowed for your own project but must be genuinely self-hostable and you must be present to answer questions. Lead with the self-hosting angle, not the AI hype. No URL shorteners. Do NOT post the same title/body to multiple subreddits the same day (looks like spam and r/selfhosted mods notice). Best time: Weekday mornings US Eastern (8–11am ET). This community skews US/EU. {{PLAY_URL}} = https://play.google.com/store/apps/details?id=cc.agentlabs.opencode once Play approval lands.

Title:

OpenCode Mobile – Android client for your self-hosted opencode AI coding agent (MIT, no backend, your keys)

Body:

I run opencode on my home server for AI-assisted coding. Great at the desk — away from the desk, I had nothing. So I built a mobile client.

What it is

OpenCode Mobile connects to your own opencode server over whatever you already use to reach home — local Wi-Fi, Tailscale, Cloudflare Tunnel, or ngrok. You type the server URL into the app and that's your entire infrastructure footprint. No cloud service of mine ever touches your traffic.

• Token-by-token streaming chat from your server
• Inline diff viewer for every file change the agent proposes
• Tool-call approval — you explicitly approve file writes and shell commands before they execute
• Multiple saved connections (home server, VPS, work box)
• Biometric unlock; connection secrets in the Android Keystore
• MIT licensed, source on GitHub

What it is not

Not a standalone AI model. You need opencode running:

npm install -g opencode-ai
OPENCODE_SERVER_PASSWORD=yourpassword opencode serve --hostname 0.0.0.0 --port 4096

Your API keys stay on your server. No accounts, no analytics, no proprietary backend. Sentry crash reporting is opt-in and off by default.
