Run [OpenCode](https://opencode.ai) in your browser. Install the CLI, open `localhost:3000`, done. Works on desktop browsers, tablets, and phones as a PWA.

Full project overview, screenshots, and all features: [github.com/btriapitsyn/openchamber](https://github.com/btriapitsyn/openchamber)

## Install

```bash
curl -fsSL https://raw.githubusercontent.com/btriapitsyn/openchamber/main/scripts/install.sh | bash
```

Or install manually: `bun add -g @openchamber/web` (or npm, pnpm, yarn).

> **Prerequisites:** [OpenCode CLI](https://opencode.ai) installed, Node.js 20+.

## Usage

```bash
openchamber                          # Start on port 3000
openchamber --port 8080              # Custom port
openchamber --ui-password secret     # Password-protect UI
openchamber tunnel help              # Tunnel lifecycle commands
openchamber tunnel providers         # Show provider capabilities
openchamber tunnel profile add --provider cloudflare --mode managed-remote --name prod-main --hostname app.example.com --token <token>
openchamber tunnel start --profile prod-main
openchamber tunnel start --provider cloudflare --mode quick --qr
openchamber tunnel start --provider cloudflare --mode managed-local --config ~/.cloudflared/config.yml
openchamber tunnel status --all      # Show tunnel state across instances
openchamber tunnel stop --port 3000  # Stop tunnel only (server stays running)
openchamber logs                     # Follow latest instance logs
OPENCODE_PORT=4096 OPENCODE_SKIP_START=true openchamber                    # Connect to external OpenCode server
OPENCODE_HOST=https://myhost:4096 OPENCODE_SKIP_START=true openchamber  # Connect via custom host/HTTPS
openchamber stop                     # Stop server
openchamber update                   # Update to latest version
```

### Tunnel behavior notes

- One active tunnel per running OpenChamber instance (port).
- Starting a different tunnel mode/provider on the same instance replaces the active tunnel.
- Replacing or stopping a tunnel revokes existing connect links and invalidates remote tunnel sessions.
- Connect links are one-time tokens; generating a new link revokes the previous unused link.

**Optional env vars:**
```yaml
environment:
  UI_PASSWORD: your_secure_password
  OPENCHAMBER_TUNNEL_MODE: quick # quick | managed-remote | managed-local
  OPENCHAMBER_TUNNEL_PROVIDER: cloudflare
```

For `managed-remote` mode, also set:

```yaml
environment:
  OPENCHAMBER_TUNNEL_MODE: managed-remote
  OPENCHAMBER_TUNNEL_HOSTNAME: app.example.com
  OPENCHAMBER_TUNNEL_TOKEN: <token>
```

For `managed-local` mode, you can set:

```yaml
environment:
  OPENCHAMBER_TUNNEL_MODE: managed-local
  OPENCHAMBER_TUNNEL_CONFIG: /home/openchamber/.cloudflared/config.yml
```

Managed-local path note: `OPENCHAMBER_TUNNEL_CONFIG` must use a container path under `/home/openchamber/...`. If the config file references `credentials-file`, ensure that JSON path is also mounted and reachable inside the container.

**Data directory:** mount `data/` for persistent storage. Ensure permissions:
```bash
mkdir -p data/openchamber data/opencode/share data/opencode/config data/ssh
chown -R 1000:1000 data/
```

<summary>Background & daemon mode</summary>

```bash
openchamber             # Runs in background by default
openchamber stop        # Stop background server
```

</details>
