Run your opencode terminal sessions anywhere — in a clean browser UI, on desktop or mobile.

✨ What is OpenCode TUI Tunnel?

OpenCode TUI Tunnel is a web tunnel for opencode terminal sessions. It gives you a browser-accessible workspace where you can launch, view, and manage multiple opencode sessions without being tied to a single terminal window.

It exists to make terminal-first workflows easier to access anywhere: local laptop, remote machine, desktop browser, or phone — while keeping sessions persistent through tmux.

🚀 Key Features

🖥️ Browser terminal — Multi-terminal grid with draggable splitters, resizable panes, keyboard navigation (Ctrl/Cmd+Arrow), context menu, and drag-to-reorder tabs
📊 Dashboard — Modern glass dashboard with Recent Projects hero section, filter chips (All/Local/SSH/Active/Discovered), unified sessions list, compact LaunchBar, and collapsible SSH connections panel
🎨 Design System — Dark dev-tool premium visual language with glassmorphism surfaces, Geist + JetBrains Mono typography, soft radius tokens, and full accessibility pass (skip-link, focus-trap, reduced-motion, contrast AA)
🧩 12 UI primitives — Reusable component library: Button (4 variants), Card (glass/solid), Dialog (focus-trap), Input, Select, Toggle, Tooltip, Badge, StatusDot, Icon, Toast, ToastProvider — all CSS-token-driven
🔔 Global toast system — Non-blocking notifications for errors (auto-dismiss 5s, pause on hover, swipe on mobile, aria-live)
⚙️ Multi-section Settings — Dedicated settings modal with Notifications, Appearance (reduce motion, font size), Terminal (scrollback, font size), and Keyboard sections
🔐 SSH connection management — Glass card list with keyboard navigation, Dialog-based create/edit with segment controls (auth type: Key/Agent, provider: Server/Local)
📱 Mobile-adaptive interface — Floating glass keybar with 44px touch targets, adaptive layouts, reduced-motion and reduced-transparency fallbacks
📲 PWA with install CTA — Full PWA support with install banner (consuming beforeinstallprompt), iOS instructions, update toast with reload, offline-ready
🧠 Multi-session tmux management — Launch, attach, kill, and organize multiple concurrent terminal sessions backed by tmux
⚙️ OpenCode version selector — Switch between opencode v1 and v2 in Settings → OpenCode

🎯 Use Cases

👨‍💻 Developers who want persistent opencode sessions across devices
🧪 AI-assisted coding workflows where multiple terminal sessions run in parallel
🏠 Homelab / remote workstation users who need secure browser access without opening inbound ports
📱 On-the-go debugging from a phone when you're away from your primary machine

opencode v2 (beta)

This project supports both opencode v1 and the new opencode v2 (beta). You can choose which version to use directly from the dashboard header.

Installing opencode v2

opencode v2 is available as the @next tag on npm:

# Install globally
npm install -g @opencode-ai/cli@next

# Or with other package managers
bun install -g @opencode-ai/cli@next
pnpm install -g @opencode-ai/cli@next
yarn global add @opencode-ai/cli@next

Standalone mode

opencode v2 supports a standalone mode that runs without a project context:

opencode2 --standalone

Standalone sessions are identified with a standalone badge in the session list and workspace tabs, making them easy to distinguish from project-bound sessions.

Documentation

opencode v1 docs: https://opencode.ai/docs
opencode v2 docs: https://v2.opencode.ai

Switching versions

Open the Settings panel in the web UI
Go to the OpenCode section
Select v1 or v2 from the version selector
New sessions will use the selected version

The doctor command (opencode-tui-tunnel doctor) will check for both opencode and opencode2 in your PATH.

Usage

Start the server (daemon mode)

opencode-tui-tunnel start

start now launches the service in the background, prints the service URL and PID, and exits the parent process after startup.

Example output:

URL: http://127.0.0.1:4096
PID: 12345

If the service is already running, the command reports the existing URL/PID instead of starting a duplicate process.

PWA Support

@igovet/opencode-tui-tunnel web UI supports Progressive Web App (PWA) behavior on compatible browsers. This lets you install the app-like experience on desktop and mobile while still serving from your local tunnel URL.

What PWA support means in this project

A web app manifest (/manifest.webmanifest) defines app metadata and icons.
A service worker (/sw.js) provides offline-capable caching behavior for app shell/navigation.
On supported platforms, the app can be installed to desktop or home screen and launched in standalone/full-screen style UI.

Benefits

Offline support (service worker): cached app shell can still load when connectivity is intermittent.
Home screen / app launcher icon: installable icon on desktop/mobile launch surfaces.
Full-screen / standalone experience: app opens without standard browser tab chrome on supported platforms.
Push notifications: not currently configured in this project.

Desktop installation

Google Chrome: Menu (⋮) → Install app
Microsoft Edge: Menu (…) → Apps → Install
Mozilla Firefox: install flow is not currently supported; use the app directly in the browser tab.

Mobile installation

iOS Safari: Share → Add to Home Screen
Android Chrome: Menu (⋮) → Add to Home Screen

Platform quick guide

Start the service:
```
opencode-tui-tunnel start
```
Open the printed URL in your platform browser.
Follow the install path above for your browser/device.
Launch from the installed icon (desktop app list or mobile home screen).

How it works

Sessions are managed by tmux — sessions survive browser refreshes and server restarts. The web UI shows all active opencode sessions. Click to connect, or launch new sessions in any project directory.

On service start, the app also checks for package updates in the background. For global npm installs, it can apply updates automatically in a detached worker. Updated code is used on the next restart of the service/process.

Mobile support

Full mobile terminal support with custom key bar (Esc, Tab, Ctrl, arrows, etc.).

Configuration

Config is stored at ~/.config/opencode-tui-tunnel/config.json.

Key settings:

server.port — default: 4096
paths.allowedRoots — directories where new sessions can be launched
sessions.maxConcurrent — max concurrent sessions (default: 8)

🎨 2026 UI Redesign

The visual interface has been fully redesigned with a "dark dev-tool premium" aesthetic inspired by tools like Linear, Warp, and Arc.

Design System

Colors: Deep #05060a base with glass surfaces (backdrop-filter: blur(12-20px) + subtle 1px border), accent-blue highlights, and gradient accents
Typography: Geist for UI text, JetBrains Mono for terminal content — loaded via non-blocking preconnects
Spacing/Radius: Soft radius tokens (4px/6px/8px) for cards and dialogs; 0px radius for terminal panes for a crisp edge
Zero hardcoded hex policy — all colors, spacing, and typography reference CSS custom properties from a centralized design token system

Dashboard

The main landing page (SessionList) has been redesigned from scratch:

Recent Projects hero — Full-width card grid showing the most recent sessions with one-click "Resume" buttons, backend badges, and relative timestamps
Filter chips — All / Local / SSH / Active / Discovered filter buttons to narrow the session list
Unified sessions list — Merged view of local, SSH, and auto-discovered sessions with consistent row structure (status dot, title, path, backend badge, running time, "Open" action)
Compact LaunchBar — A streamlined command bar with path autocomplete (ARIA combobox), backend selector, and "Run session" button
Collapsible SSH panel — SSH connections section collapsed by default; expand to see connection cards with keyboard navigation

Workspace & Multi-Terminal Grid

The workspace view (WorkspaceView) powers the multi-terminal experience:

Chrome-style tabs — Compact 30px pill tabs with close-on-hover, circular "+" button inside tab strip, drag-to-reorder, right-click context menu (Close / Close others / Close right / Move left / Move right)
Terminal panes — Slim 28px chrome header with pane title, status dot, backend badge, zoom dropdown; active pane gets glow ring; inactive chrome dims while xterm stays full brightness
Draggable splitters — Pointer Events-based drag-resize with 15% minimum pane width for reliable resizing
Keyboard navigation — Ctrl/Cmd+ArrowLeft/Right for pane switching (capture-phase to override xterm word-jump)

Components & Primitives

12 reusable UI primitives live in web/src/components/ui/:

Button, Card, Dialog, Input, Select, Toggle, Tooltip, Icon, Badge, StatusDot, Toast, ToastProvider

All components use var(--*) design tokens and follow the zero-hardcoded-hex policy.

Accessibility

Skip-link as first focusable element
Focus-trap in all dialog-based modals
ARIA combobox on PathAutocomplete
WCAG AA contrast on all text (4.5:1 minimum)
prefers-reduced-motion disables hover/active transforms
prefers-reduced-transparency reduces glass blur

Push Notifications & Toasts

Global ToastProvider renders system-style toasts for API errors, session events, and PWA updates
Auto-dismiss after 5s, pause on hover, swipe-to-dismiss on mobile
Push notifications via Web Push API (VAPID) for session activity when browser is backgrounded

SSH Connections

OpenCode TUI Tunnel supports connecting to remote servers via SSH, allowing you to launch and manage opencode sessions on remote machines directly from the browser UI.

Setting up an SSH connection

Open the web UI and switch to the SSH tab.
Click + NEW CONNECTION to open the connection modal.
Fill in the required fields:
- Name — A friendly label for this connection (e.g., "Home Server")
- Host — The SSH server hostname or IP address
- Port — SSH port (default: 22)
- Username — Your SSH login username
- Authentication — Choose between:
  - SSH key — Select a private key file (supports encrypted keys with passphrase)
  - SSH agent — Use your system's running SSH agent
Configure opencode settings:
- Provider — local (run opencode on the remote server) or server (use the remote server's opencode installation)
- Command — Optional custom opencode launch command
Click Save to store the connection.

Using SSH connections

Launch remote sessions: Select an SSH connection from the dropdown and enter a project path to start an opencode session on the remote server.
Remote tmux discovery: The SSH tab shows all running tmux sessions on the remote server. Click Attach to connect to any existing session.
Manage connections: Use the connection list to edit, test, or delete saved SSH connections.

SSHFS (optional)

If SSHFS is available on your system, the app can automatically mount remote directories for local path browsing when launching remote sessions.

Cloudflare Tunnel Setup (Zero Trust Authentication)

Use this when you want secure remote access to opencode-tui-tunnel without opening inbound firewall ports or configuring router port forwarding.

1) Overview

Cloudflare Tunnel (cloudflared) creates an outbound-only connection from your machine to Cloudflare's edge. Requests to your public hostname are then proxied to your local opencode-tui-tunnel service.

Why this is useful for @igovet/opencode-tui-tunnel:

Secure remote browser access to your local TUI sessions
No public inbound port exposure
Works well with Cloudflare Zero Trust Access policies

2) Prerequisites

A Cloudflare account
A domain managed in Cloudflare DNS
Cloudflare Zero Trust enabled for your account/team
opencode-tui-tunnel running locally (default http://127.0.0.1:4096)

3) Install `cloudflared` and authenticate

Install cloudflared (pick your platform package from Cloudflare docs):

https://developers.cloudflare.com/cloudflare-one/connections/connect-networks/downloads/

Authenticate the CLI with your Cloudflare account:

cloudflared tunnel login

This opens a browser to authorize cloudflared for your Cloudflare zone.

4) Create and route a tunnel

Create a named tunnel:

cloudflared tunnel create opencode-tui-tunnel

Route a public hostname to the tunnel (example hostname):

cloudflared tunnel route dns opencode-tui-tunnel tunnel.example.com

5) Configure Zero Trust authentication

Open Cloudflare Dashboard → Zero Trust → Access → Applications.
Click Add an application and choose Self-hosted.
Set the application domain to your tunnel hostname (for example tunnel.example.com).
Create an Access policy (for example, allow specific emails/groups).
In login methods, enable:
- your SSO IdP (Google, GitHub, Okta, Azure AD, etc.), and/or
- One-time PIN.

Note: Cloudflare Access does not provide a standalone local username/password database. "Password authentication" is typically handled by your configured IdP login flow, or by One-time PIN.

6) Example `cloudflared` config

Create ~/.cloudflared/config.yml:

tunnel: <TUNNEL_UUID>
credentials-file: /home/<user>/.cloudflared/<TUNNEL_UUID>.json

ingress:
  - hostname: tunnel.example.com
    service: http://localhost:4096
  - service: http_status:404

Run the tunnel:

cloudflared tunnel run opencode-tui-tunnel

7) Test the setup

Start the local service:
```
opencode-tui-tunnel start
```
Start cloudflared (if not already running).
Open https://tunnel.example.com in a browser.
Confirm you are prompted by Cloudflare Access before the app loads.
Sign in via your configured method (SSO or One-time PIN) and verify the TUI page loads.

8) Troubleshooting

502 / connection errors from Cloudflare
- Verify opencode-tui-tunnel is running on port 4096.
- Check service: http://localhost:4096 in config.yml.
Hostname does not resolve or route correctly
- Re-run cloudflared tunnel route dns ... and verify DNS record exists in Cloudflare.
- Allow time for DNS propagation.
Access login prompt not shown
- Verify the Zero Trust Access app domain exactly matches the tunnel hostname.
- Confirm policy is active and not bypassed by broader rules.
Authentication denied / login loop
- Confirm your user/group/email matches the Access policy allow rules.
- Confirm the configured IdP is healthy and enabled.
cloudflared credentials or tunnel not found
- Re-run cloudflared tunnel login.
- Check that the tunnel name/UUID in config.yml is correct.
