**OpenCode, everywhere.** Desktop. Browser. Phone.

A GUI for [OpenCode](https://opencode.ai) that works alongside the TUI — start a session in your terminal, pick it up on your phone, finish it on your laptop. Same conversation, any screen.

## Why a GUI?

OpenCode's TUI is excellent. OpenChamber is for those moments when you want a visual workspace — reviewing diffs side-by-side, keeping an eye on multiple agents at once, or just continuing a session from your phone while away from the keyboard.

They share the same sessions. Use whatever feels right.

## Highlights

- **Use it from anywhere** — Cloudflare tunnel with QR code onboarding. Scan, connect, code from your couch.
- **Branchable chat timeline** — Undo, redo, fork from any turn. Explore different approaches without losing your place.
- **GitHub-native workflows** — Start sessions from issues and PRs with context already attached. Review checks, merge — all in-app.
- **Project Actions** — Run dev servers, configure SSH port forwarding, open remote URLs locally. Your project commands, one click away.
- **Connect to remote machines** — Desktop app connects to remote OpenChamber instances over SSH, with dedicated lifecycle and UX flows.

## Quick Start

> **Prerequisite:** [OpenCode CLI](https://opencode.ai) installed.

**Desktop (macOS)** — Download from [Releases](https://github.com/btriapitsyn/openchamber/releases).

**VS Code** — Install from [Marketplace](https://marketplace.visualstudio.com/items?itemName=fedaykindev.openchamber) or search "OpenChamber" in Extensions.

**CLI (Web + PWA)** — requires Node.js 20+

```bash
curl -fsSL https://raw.githubusercontent.com/btriapitsyn/openchamber/main/scripts/install.sh | bash
openchamber --ui-password be-creative-here --daemon
```

<details>
<summary>Advanced CLI options</summary>

```bash
openchamber --port 8080              # Custom port
openchamber --daemon                 # Background mode
openchamber --ui-password secret     # Password-protect UI
openchamber --try-cf-tunnel          # Cloudflare Quick Tunnel
openchamber --try-cf-tunnel --tunnel-qr              # + QR code
openchamber --try-cf-tunnel --tunnel-password-url     # + password in URL
openchamber stop                     # Stop server
openchamber update                   # Update to latest
```

Connect to an existing OpenCode server:
```bash
OPENCODE_PORT=4096 OPENCODE_SKIP_START=true openchamber
OPENCODE_HOST=https://myhost:4096 OPENCODE_SKIP_START=true openchamber
```

</details>

<details>
<summary>Docker</summary>

```bash
docker compose up -d
```

Available at `http://localhost:3000`.

**UI Password:**
```yaml
environment:
  UI_PASSWORD: your_secure_password
```

**Cloudflare Tunnel:**
```yaml
environment:
  CF_TUNNEL: "true" # Options: true, qr, password
```

| Value      | Description                     |
| ---------- | ------------------------------- |
| `true`     | Enable tunnel only              |
| `qr`       | Enable tunnel + QR code         |
| `password` | Enable tunnel + password in URL |

**Data directory permissions:** The `data/` directory is mounted for persistent storage. Before running:

```bash
mkdir -p data/openchamber data/opencode/share data/opencode/config data/ssh
chown -R 1000:1000 data/
```

**SSH/Git:** If git push/pull fails, run `ssh -T git@github.com` in terminal.

</details>

<details>
<summary>Named Cloudflare Tunnel (persistent hostname)</summary>

For reliable long-lived access with a custom hostname from your Cloudflare account:

- Configure in-app at **Settings > OpenChamber > Tunnel**, switch to **Named** mode.
- Requires a domain in your Cloudflare account.
- [Cloudflare setup guide](https://developers.cloudflare.com/cloudflare-one/networks/connectors/cloudflare-tunnel/get-started/create-remote-tunnel/)
- CLI `--tunnel <config.yml>` support is coming very soon.
