\n\n---\n\n## Features\n\nA complete development environment designed around AI-assisted workflows, built to disappear into the background and just work.\n\n- **Multi-Engine Support** — Switch between Claude Code, OpenCode, Codex, GitHub Copilot, Qwen Code, Pi, Cline, and Cursor as your AI engine, per session\n- **Multi-Account Per Engine** — Manage multiple accounts per engine (personal, work, or team) and switch between them instantly per chat session\n- **Reasoning Effort Control** — Dial a model's thinking level right from the chat input, using that engine's own levels. Set a default per model in Settings, and the choice is remembered and synced across your devices\n- **Integrated Terminal** — Multi-tab xterm.js terminal with full keyboard control and complete ANSI/VT support, right inside your workspace\n- **Full Git Management** — Stage, commit, branch, push, pull, stash, log, and resolve conflicts, all from a clean UI\n- **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\n- **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\n- **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\n- **Remote Access** — Add your phone, tablet, or another computer with a one-time link or QR code. Every device stays in sync live: chats, terminals, and the browser preview\n- **Monaco File Editor** — VS Code's editor right in the browser. Full syntax highlighting, autocomplete, and live file watching, beside your AI chat\n- **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\n- **Integrations** — Connect a third-party account once and every engine and project can use it. Credentials are sealed at rest with AES-256-GCM. Includes the full MCP surface: browse the official Model Context Protocol registry, connect with OAuth or custom env/headers, control tool exposure per engine, and sync every connector across all your AI engines\n- **Skills, Commands & Subagents** — Build reusable Skills, slash Commands, delegated Subagents, shared Instructions, and tool Permissions or Profiles once, synced automatically across every engine\n- **Flexible Authentication** — No Login or With Login mode, one-time device pairing links, rate-limited login, and CLI token recovery\n- **Stack** — Install AI engines, Git, Chrome, and Cloudflared (for Public Tunnel) from a one-click panel. Engines install on demand into a clopen-managed directory (`~/.clopen/stack/engines`) — isolated from your global setup, no PATH pollution\n- **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\n- **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\n\n---\n\n## Quick Start\n\n### Prerequisites\n\n- [Bun.js](https://bun.sh/) v1.2.12+\n- At least one supported AI engine — [Claude Code](https://github.com/anthropics/claude-code), [OpenCode](https://opencode.ai), [Codex](https://github.com/openai/codex), [GitHub Copilot CLI](https://github.com/github/copilot-cli), [Qwen Code](https://github.com/QwenLM/qwen-code), [Pi](https://github.com/earendil-works/pi), [Cline](https://github.com/cline/cline), or [Cursor](https://cursor.com). All install on demand from **Settings → Stack** after first launch (nothing is bundled into the clopen install), then sign in from **Settings → Engines**\n\n### Installation\n\n```bash\nbun add -g @myrialabs/clopen\n```\n\n### Update\n\n```bash\nclopen update\n```\n\nOr manually via Bun:\n\n```bash\nbun add -g @myrialabs/clopen\n```\n\nYou can also update from the **Settings → Maintenance → Updates** section in the web UI.\n\n### Usage\n\n```bash\nclopen\n```\n\nStarts the server on `http://localhost:9141`.\n\n### First-Time Setup\n\nOn first launch, a setup wizard guides you through:\n\n1. **Authentication mode** — Choose between **No Login** (no authentication required, ideal for personal/local use) or **With Login** (login with a Personal Access Token, recommended when Clopen is reachable from other devices or the internet)\n2. **Account** — If With Login mode is selected, create your account and save the generated PAT\n3. **Stack** — Install Git, Chrome, Cloudflared, and any AI engine you don't have yet — straight from the wizard, no terminal needed\n4. **AI Engines** — Check installation status for every engine and sign in to the ones you'll use. An engine that isn't installed yet links straight back to the Stack step\n5. **Preferences** — Set dark mode, font size, sound notifications, and message layout (Classic cards or Compact lines)\n\nYou can change the authentication mode anytime in **Settings → Sign-in & Devices**.\n\nTo sign in another of your devices, open **Remote Access → Add a device** and scan the one-time link (valid for 5 minutes).\n\nIf you lose your token:\n\n```bash\nclopen reset-pat\n```\n\nThis regenerates and displays a new PAT.\n\n---\n\n## Contributing\n\nClopen 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.\n\n```bash\ngit clone https://github.com/myrialabs/clopen.git\ncd clopen\nbun install\nbun run dev # Start development server\nbun run check # Type checking\n```\n\nWhen running in development mode, Clopen uses `~/.clopen-dev` instead of `~/.clopen`, keeping dev data separate from any production instance.\n\nEach AI engine's config/state (credentials, sessions, logs) is isolated under `~/.clopen/engine/
