## Why use OpenChamber?
## What you can do with OpenChamber
- **Cross-device continuity**: Start in TUI, continue on tablet/phone, return to terminal - same session
- **Remote access**: Use OpenCode from anywhere via browser
- **Familiarity**: A visual alternative for developers who prefer GUI workflows
### Goals that continue on their own
## Features
Give a session a finish line with **Session Goals**. OpenChamber checks the result after every turn and keeps the agent working until the goal is complete, blocked, or reaches the limit you set — even after you close the app.
### Core (all app versions)
### Compare and combine runs
- Branchable chat timeline with `/undo`, `/redo`, and one-click forks from earlier turns
- Smart tool UIs for diffs, file operations, permissions, and long-running task progress
- Voice mode with speech input and read-aloud responses for hands-free workflows
- Multi-agent runs from one prompt with isolated worktrees for safe side-by-side comparisons
- Git workflows in-app: identities, commits, PR creation, checks, and merge actions
- GitHub-native workflows: start sessions from issues and pull requests with context already attached
- Plan/Build mode with a dedicated plan view for drafting and iterating implementation steps
- Inline comment drafts on diffs, files, and plans that can be sent back to the agent
- Context visibility tools (token/cost breakdowns, raw message inspection, and activity summaries)
- Integrated terminal with per-directory sessions and stable performance on heavy output
- Built-in skills catalog and local skill management for reusable automation workflows
Use **Multi-run** to give the same task to up to five models, each in its own session and optionally its own worktree. See what each one actually built, choose the best result, or use **Fusion** to combine the strongest parts into a new session.
### Web / PWA
### Guided changes walkthroughs
- Provider-aware tunnel access model with Cloudflare `quick`, `managed-remote`, and `managed-local` modes
- One-scan onboarding with tunnel QR + password URL helpers
- Mobile-first experience: optimized chat controls, keyboard-safe layouts, and attachment-friendly UI
- Background notifications plus reliable cross-tab session activity tracking
- Built-in self-update + restart flow that keeps your server settings intact
**Changes Walkthrough** turns a large diff into an AI-guided tour of the change. It groups related edits into steps, puts them in the order the change makes sense, and explains how the pieces fit together.
### Desktop (macOS + Windows + Linux)
### Inspect a running app
- Floating Mini Chat: keep a small always-on-top assistant beside your editor, browser, or terminal
- Multiple native windows for separate projects or sessions
- Native notifications for task alerts while OpenChamber is hidden
- One-click open in VS Code, Cursor, Terminal, Finder, Explorer, and more
- Desktop host switcher for local and remote OpenChamber instances
- Convenient tunnel management without manual setup
- Deep-link connections for joining remote OpenChamber from a link
- SSH remote access with host import, connection management, and port forwarding
Open your app beside the conversation with **Preview**. Point at an element and send the agent its screenshot, styles, position, and browser errors — all the context behind “this thing here.” Desktop brings the same workflow to any web page through its built-in browser.
### VS Code Extension
### GitHub context from issue to pull request
- Editor-native workflow: open files directly from tool output and keep sessions beside your code
- Agent Manager for parallel multi-model runs from a single prompt
- Right-click actions to add context, explain selections, and improve code in-place
- In-extension settings, responsive layout, and theme mapping that matches your editor
- Hardened runtime lifecycle and health checks for faster startup and fewer stuck reconnect states
Start a session from a GitHub issue or pull request with its context attached. Send failed checks or review comments back to the agent, then update or merge the pull request from OpenChamber.
### Custom Themes
### Continue on another device
- **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.
Open the same projects and sessions from Desktop, Web/PWA, VS Code, iOS, or Android. Check progress, answer questions, review changes, and reattach to a running terminal.
## Quick Start
### Private remote access
> **Prerequisite:** Desktop bundles the matching OpenCode CLI. CLI/Web and VS Code use your installed [OpenCode CLI](https://opencode.ai).
Pair a device with a one-time QR code and connect through **Private Relay** without opening ports or exposing a public server. The connection is end-to-end encrypted and can be revoked at any time. Direct connections, LAN/VPN access, Cloudflare/Ngrok tunnels, and SSH are also supported.
### **Desktop (macOS + Windows + Linux)**
### Track work across projects
Download the latest Desktop release from [GitHub Releases](https://github.com/openchamber/openchamber/releases).
See which sessions are working, waiting, finished, or failed, along with approvals, scheduled tasks, provider limits, token use, and costs. Organize sessions into folders and keep notes, todos, and reusable project actions nearby.
On Linux, choose the AppImage for your system:
### Schedule recurring work
- `linux-x86_64.AppImage` for 64-bit Intel or AMD systems
- `linux-arm64.AppImage` for ARM64/aarch64 systems
Run a prompt once, daily, weekly, or on a cron schedule. Scheduled tasks can use Session Goals, so they continue toward an outcome instead of stopping after one response.
Make the AppImage executable before launching it, for example with `chmod +x <downloaded-appimage>`. Keep the AppImage in a location your user can write to so OpenChamber can download and apply in-app updates.
## Use it where you work
Linux AppImages need FUSE (`libfuse.so.2`). On Ubuntu/Debian install `libfuse2` (or `fuse` / `libfuse2t64` on newer releases). If FUSE is unavailable, run with extraction instead:
| Surface | Role |
| --- | --- |
| **Desktop** | The complete workspace for macOS, Windows, and Linux, with multiple windows, Mini Chat, remote machines, SSH, and native notifications |
| **Web / PWA** | Open your workspace in a browser, install it as an app, and stay up to date through background notifications |
| **VS Code** | Keep sessions beside your code, send selections to the agent, open results in the editor, and compare parallel runs |
| **iOS / Android** | Review and steer work away from your desk, receive completion alerts, and use the terminal with touch controls |
| **CLI / Server** | Run OpenChamber on a workstation or server, schedule work, manage remote access, and keep it available after login |
## Quick start
### Desktop — macOS, Windows, and Linux
Download the latest release from [GitHub Releases](https://github.com/openchamber/openchamber/releases/latest). Desktop bundles the matching OpenCode CLI, so no separate OpenCode installation is required.
Linux releases are available as x86_64 and ARM64 AppImages. Make the downloaded AppImage executable and keep it in a writable location for in-app updates:
```bash
APPIMAGE_EXTRACT_AND_RUN=1 ./OpenChamber-*-linux-*.AppImage
chmod +x OpenChamber-*.AppImage
./OpenChamber-*.AppImage
```
Linux Desktop ships as AppImage with in-app window controls and auto-update when running from a writable AppImage.
Linux AppImages require FUSE (`libfuse.so.2`). Without FUSE, run with `APPIMAGE_EXTRACT_AND_RUN=1`.
### **VS Code**
Install from [Marketplace](https://marketplace.visualstudio.com/items?itemName=fedaykindev.openchamber) or search "OpenChamber" in Extensions.
### VS Code
### **CLI (Web + PWA)**
_requires Node.js 22+_
Install [OpenChamber from the Visual Studio Marketplace](https://marketplace.visualstudio.com/items?itemName=fedaykindev.openchamber), or search for “OpenChamber” in Extensions.
### CLI — Web and PWA
Requires Node.js 22+. CLI/Web and VS Code use your installed [OpenCode CLI](https://opencode.ai).
```bash

openchamber stop # Stop server
openchamber update # Update to latest
openchamber startup enable
openchamber logs
openchamber stop
openchamber update
```
`startup enable` snapshots your current environment into the native service so startup behaves like you launched `openchamber` from the same shell. This preserves provider tokens, PATH, SSH agent settings, and other CLI auth/config env vars. Use `--no-env-snapshot` if you want a minimal service env.
OpenChamber binds to localhost by default. Use `--lan` only on a trusted network and protect browser access with `--ui-password`.
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
```
## Guides
Bind managed OpenCode server to all interfaces (use only on trusted networks):
```bash
OPENCHAMBER_OPENCODE_HOSTNAME=0.0.0.0 openchamber --port 3000
```
Go deeper with the OpenChamber guides:
Expose OpenChamber itself on your LAN:
```bash
openchamber --lan --port 3000 --ui-password secret
```

Add this server to OpenChamber Desktop or another OpenChamber app:
```bash
openchamber connect-url --port 3000 --qr
```
For self-hosting details, see the [reverse proxy guide](docs/REVERSE_PROXY.md). For custom theme authoring, see the [custom themes guide](docs/CUSTOM_THEMES.md).
If no OpenChamber server is running on that port, `connect-url` starts one before generating the link.
## Why OpenCode?
Headless/API-only setup for a remote machine:
```bash
openchamber connect-url --port 3000 --api-only --lan --server http://your-host-or-ip:3000 --qr --ui-password secret
```
OpenChamber uses [OpenCode](https://opencode.ai) to power its coding agents. We chose it because we believe it provides the best open-source agentic coding experience today: capable, extensible, and open by design.
This runs OpenChamber as an API-only server without the desktop app or browser UI assets on that machine, then creates a link for Desktop to import. `--lan` makes the server reachable from other machines. `--server` is the address Desktop should use.
Around that foundation, OpenChamber brings together the work that happens before, during, and after an agent run — deciding what to try, keeping it on track, reviewing the result, connecting from anywhere, and getting the change shipped.
When OpenChamber was started with `--lan` or `--host 0.0.0.0`, `connect-url` automatically uses a detected LAN IP instead of `127.0.0.1`. Use `--server http://host:3000` to override the advertised address, and include `--lan` when `connect-url` needs to start the server for LAN access.
Paste the printed `openchamber://connect?...` link in Desktop under Settings -> Remote Instances -> Direct Instances -> Import Link. The link contains the server URL and a client token. It does not enable browser UI password protection; use `--ui-password` when exposing a server beyond localhost.

<summary>systemd service (VPN / LAN access)</summary>
Run OpenChamber and OpenCode as separate persistent services — useful when you want to access your
dev machine over a VPN (e.g. Tailscale) or LAN without a Cloudflare tunnel.
**How it works:**
- OpenCode runs as its own service, binding only to `localhost`.
- OpenChamber connects to it via `OPENCODE_HOST` and `--lan` makes it reachable on your VPN IP.
- `--foreground` keeps the CLI process alive so systemd can track and restart it.
**`~/.config/systemd/user/opencode.service`**
```ini
[Unit]
Description=OpenCode Server
[Service]
Type=simple
ExecStart=opencode serve --port 4095
Environment="PATH=/home/linuxbrew/.linuxbrew/bin:/home/linuxbrew/.linuxbrew/sbin:/home/YOU/.local/bin:/home/YOU/.npm-global/bin:/usr/local/bin:/usr/bin:/bin"

Restart=on-failure
RestartSec=5
[Install]
WantedBy=default.target
```
> **Why set `PATH` and `SSH_AUTH_SOCK`?**
> systemd user services start with a minimal environment — no shell profile is sourced.
> Without an explicit `PATH`, OpenCode won't find tools installed via Homebrew, npm, or `~/.local/bin`.
> Without `SSH_AUTH_SOCK`, git operations over SSH (push, pull, clone) will fail because the agent socket isn't inherited.
> Adjust the `PATH` to match your own tool installation paths.
> `%t` expands to `$XDG_RUNTIME_DIR` (e.g. `/run/user/1000`), where most SSH agents write their socket.

OpenChamber will be reachable at `http://<your-vpn-hostname>:3000` from any device on your VPN.
> **Note:** `--host 0.0.0.0` is required to listen on all interfaces. The default
> bind address is `127.0.0.1` (localhost only). Use `--host <ip>` or
> `OPENCHAMBER_HOST=<ip>` to bind to a specific interface instead.

<summary>Docker</summary>
```bash
docker compose up -d
```
Available at `http://localhost:3000`.
**UI Password:**
```yaml
environment:
UI_PASSWORD: your_secure_password
```
**Cloudflare Tunnel (optional):**
```yaml
environment:
OPENCHAMBER_TUNNEL_MODE: quick # quick | managed-remote | managed-local
OPENCHAMBER_TUNNEL_PROVIDER: cloudflare
```
For `managed-remote` mode, provide:
```yaml
environment:
OPENCHAMBER_TUNNEL_MODE: managed-remote
OPENCHAMBER_TUNNEL_HOSTNAME: app.example.com
OPENCHAMBER_TUNNEL_TOKEN: <token>
```
For `managed-local` mode, optionally provide:
```yaml
environment:
OPENCHAMBER_TUNNEL_MODE: managed-local
OPENCHAMBER_TUNNEL_CONFIG: /home/openchamber/.cloudflared/config.yml
```
Managed-local path note: `OPENCHAMBER_TUNNEL_CONFIG` must point to a path inside the container user home (`/home/openchamber/...`). If your Cloudflare config references a credentials JSON file, that file path must also be accessible inside the container (mount with `volumes`).
### Reverse proxy notes
- For a complete reverse proxy setup guide, see [`docs/REVERSE_PROXY.md`](./docs/REVERSE_PROXY.md).
- Website docs source lives at `packages/docs/content/docs/reverse-proxy.mdx`.
### Tunnel behavior notes
- OpenChamber supports one active tunnel per running instance (port).
- Starting a tunnel with a different mode/provider on the same instance replaces the current tunnel.
- Replacing or stopping a tunnel revokes existing connect links and invalidates remote tunnel sessions for that instance.
- Connect links are one-time tokens; generating a new link revokes the previous unused link.
**Data Directory Permission Note:** The `data/` directory is mounted into the container for persistent storage (config, sessions, SSH keys, workspaces). Before running, ensure the directory exists and has proper permissions:
```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.
