Features

A complete development environment designed around AI-assisted workflows, built to disappear into the background and just work.

• Multi-Engine Support — Switch between Claude Code, OpenCode, Codex, GitHub Copilot, and Qwen Code as your AI engine, per session
• Multi-Account Per Engine — Manage multiple accounts per engine (personal, work, or team) and switch between them instantly per chat session
• Integrated Terminal — Multi-tab xterm.js terminal with full keyboard control and complete ANSI/VT support, right inside your workspace
• Full Git Management — Stage, commit, branch, push, pull, stash, log, and resolve conflicts, all from a clean UI
• Real Browser Preview — A live browser preview streams directly into your workspace. Interact with your app manually, or let the AI drive: clicking, typing, and scrolling for autonomous visual testing
• Database Client — Connect to PostgreSQL, MySQL, SQLite, MongoDB, and Redis. Browse schemas, run queries, and inspect data, with optional SSH tunneling for databases behind a bastion
• Git-Like Checkpoints — Multi-branch undo/redo with full file snapshots. Roll back to any point in your AI conversation without touching your actual git history
• Real-Time Collaboration — See who's working on which project, and collaborate live in the same codebase
• Monaco File Editor — VS Code's editor right in the browser. Full syntax highlighting, autocomplete, and live file watching, beside your AI chat
• Cloudflare Tunnel — One-click public HTTPS URL for your local dev server. Built-in QR code for instant mobile access. Share your work without deploying
• Connectors (MCP) — Browse a searchable catalog of Model Context Protocol servers, connect with OAuth or custom env/headers, and sync every connector across all your AI engines
• Skills, Commands & Subagents — Build reusable Skills, slash Commands, delegated Subagents, shared Instructions, and tool Permissions or Profiles once, synced automatically across every engine
• Flexible Authentication — No Login or With Login mode with admin/member roles, invite links, rate-limited login, and CLI token recovery
• System Tools Installer — Install Git, Claude Code, OpenCode, Codex, Copilot, Qwen Code, Chrome, and Cloudflared (for Public Tunnel) from a one-click admin panel
• Background Processing — Chat, terminal, and other processes continue running even when you close the browser — come back later and pick up where you left off
• Works on Any Device — Fully responsive across desktop, laptop, tablet, and mobile. Open your workspace from any device and continue exactly where you left off

Quick Start

Prerequisites

• Bun.js v1.2.12+
• At least one supported AI engine — Claude Code, OpenCode, Codex, GitHub Copilot CLI, or Qwen Code. All are installable from Settings → System Tools after first launch

Installation

bun add -g @myrialabs/clopen

Update

clopen update

Or manually via Bun:

bun add -g @myrialabs/clopen

You can also update from the Settings → Maintenance → Updates section in the web UI.

Usage

clopen

Starts the server on http://localhost:9141.

First-Time Setup

On first launch, a setup wizard guides you through:

1. Authentication mode — Choose between No Login (no authentication required, ideal for personal/local use) or With Login (login with Personal Access Token, supports team collaboration)
2. Admin account — If With Login mode is selected, create your admin account and save the generated PAT
3. System Tools — Install Git, Chrome, Cloudflared, and any AI engine you don't have yet — straight from the wizard, no terminal needed
4. AI Engines — Check installation status for Claude Code, OpenCode, Codex, Copilot, and Qwen Code, and sign in to the engines you'll use
5. Preferences — Set dark mode, font size, sound notifications, and message layout (Classic cards or Compact lines)

You can change the authentication mode anytime in Settings → Security → Authentication.

To invite team members (With Login mode), go to Settings → Team → Invite and generate an invite link (valid for 15 minutes).

If you lose your admin token:

clopen reset-pat

This regenerates and displays a new admin PAT.

Contributing

Clopen is open source and contributions are welcome! Whether it's a bug fix, new feature, or improvement to docs — feel free to open an issue or submit a pull request.

git clone https://github.com/myrialabs/clopen.git
cd clopen
bun install
bun run dev     # Start development server
bun run check   # Type checking

When running in development mode, Clopen uses ~/.clopen-dev instead of ~/.clopen, keeping dev data separate from any production instance.

Each AI engine's config/state (credentials, sessions, logs) is isolated under ~/.clopen/engine/<engine>/user/ rather than the engine's global location (~/.codex, ~/.copilot, ~/.qwen, the OpenCode XDG dirs), so Clopen never mixes with — or disturbs — your own standalone CLI usage.

See CONTRIBUTING.md for guidelines and DECISIONS.md for architectural decisions.
