The AI-native agentic workstation. Your desktop, amplified.

Lukan is an AI agent that turns your terminal, browser, and messaging into one intelligent workspace. 
Multi-provider, multi-interface, E2E encrypted remote access, background workers, and sandboxed execution. 
Built in Rust. Single binary. No runtime dependencies.

## Features

- **10 LLM Providers** — Anthropic, OpenAI Codex, GitHub Copilot, Fireworks, Nebius, Ollama Cloud, Zai, Gemini, Lukan Cloud, and any OpenAI-compatible endpoint (vLLM, Ollama, LM Studio)
- **Multiple Interfaces** — Terminal UI (ratatui), Web UI, Desktop app (Tauri), and CLI
- **Browser Automation** — Full Chrome DevTools Protocol: navigate, screenshot, click, type, evaluate JS, export PDF
- **Plugin System** — WhatsApp, Telegram, Slack, Email, Gmail, Google Workspace (Sheets, Docs, Calendar, Drive), Docker Monitor, and more
- **Sandboxed Execution** — OS-level isolation (bwrap), granular permission modes (Planner/Auto/Manual), sensitive file detection
- **E2E Encrypted Relay** — Access your workstation remotely with X25519 + AES-GCM encryption
- **Background Workers** — Scheduled autonomous tasks with cron-style execution
- **Persistent Memory** — Context compaction, session management, and long-term memory across conversations
- **Skills** — Markdown-based instruction system for project-specific workflows, compatible with community skill formats
- **Pipelines** — DAG-based multi-agent workflows with visual editor, parallel execution, and human-in-the-loop approval gates
- **Single Binary** — No runtime dependencies, instant startup

## Quick Start

Get up and running in 5 steps:

### 1. Install Lukan

```bash
# CLI only (includes TUI + Web UI)
curl -fsSL https://get.lukan.ai/install.sh | bash

# Or with Desktop app
curl -fsSL https://get.lukan.ai/install.sh | bash -s -- --desktop
```

**Or use Docker:**
```bash
docker pull lukanlabs/lukan
docker run -d -p 3000:3000 --name lukan lukanlabs/lukan

# Enter the container and follow steps 2-5 below
docker exec -it lukan bash
```

The web UI is accessible at `http://localhost:3000`. You can also build the image locally with `docker build -t lukan .`.

### 2. Authenticate or configure your provider

**For OAuth providers (no API key needed):**
```bash
# OpenAI Codex
lukan codex-auth

# GitHub Copilot  
lukan copilot-auth
```

**For API key providers:**
```bash
lukan setup
```
Enter your API key when prompted (Anthropic, Fireworks, Gemini, Nebius, etc.).

### 3. Select which models you want available

Choose which models from your provider will appear in the `/model` selector:

```bash
# Example: Select models from OpenAI Codex
lukan models openai-codex

# Or from Anthropic
lukan models anthropic

# Or any other provider you configured
lukan models <provider>
```

This opens an interactive selector where you pick which models to make available.

### 4. Start the agent

**Terminal UI (default)**
```bash
lukan
# or
lukan chat
```

**Web UI** — Opens your browser at http://localhost:3000
```bash
lukan chat --ui web
```

**Desktop app**
```bash
lukan chat --desktop
```

### 5. Select your model inside the chat

Once inside the chat, type:

```
/model
```

This shows the models you selected in step 3. Pick one and start chatting!

---

**Summary:** `install` → `auth/setup` → `select models` → `chat` → `/model`

Run `lukan doctor` anytime to check your configuration and troubleshoot issues.

### Continue your last session

```bash
# Resume your previous chat
lukan chat -c
```

### Browser automation

```bash
# Auto-detect and launch a browser
lukan chat --browser

# Use a specific browser
lukan chat --browser chrome
lukan chat --browser edge

# Connect to an already running browser
lukan chat --browser-cdp http://localhost:9222

# Run browser in visible mode (see what the agent does)
lukan chat --browser-visible

# Keep browser profile across sessions
lukan chat --browser --browser-profile persistent
```

### Remote access

```bash
# Log in to your relay (access lukan from any browser)
lukan login

# Check relay connection
lukan relay status
```

### Diagnostics

```bash
# Show current config, provider, model, and system info
lukan doctor

# List available models for a provider
lukan models anthropic

# Self-update
lukan update
```

### Embedded terminal

The Web and Desktop UIs include a full terminal emulator powered by xterm.js. When tmux is available, sessions are backed by tmux — they persist across page reloads, browser crashes, and reconnects, with full scrollback recovery. Without tmux, terminals fall back to direct PTY.

- Full terminal — run any CLI tool, including other agents (Claude Code, Codex CLI, OpenCode, etc.)
- Multiple terminal tabs with rename support
- Sessions panel in the sidebar to manage and switch between terminals
- Send running processes to background mid-execution
- File explorer with inline preview

### Agent tabs & sessions

Run multiple agents in parallel, each with its own context and conversation history. Sessions are saved automatically and can be loaded, rewound, or continued later.

- Multiple agent tabs — work on different tasks simultaneously
- Session checkpoints — rewind to any point in the conversation (CLI)
- Session recovery — resume after disconnects or crashes
- Background processes — long-running commands can be sent to background while the agent continues working

### Audio input

Record audio directly in the Web and Desktop UI. Transcription runs locally via the Whisper plugin using whisper.cpp with GPU/CPU auto-detection — no data leaves your machine.

```bash
# Install the whisper plugin
lukan plugin install whisper
```

## Remote Access (Relay)

Lukan includes a built-in relay system for accessing your workstation from any browser, anywhere. The connection is end-to-end encrypted — the relay server never sees your data.

```
┌──────────────┐        ┌──────────────┐        ┌──────────────┐
│   Browser    │◄──────►│  Relay Server│◄──────►│  Your Machine│
│  (any device)│  E2E   │  (cloud)     │  E2E   │  (lukan)     │
└──────────────┘  enc.  └──────────────┘  enc.  └──────────────┘
```

- **E2E Encryption** — X25519 key exchange + AES-256-GCM. The relay only forwards opaque ciphertext.
- **Google OAuth** — Login with your Google account, no extra credentials to manage.
- **Full Web UI** — Same interface as local `--ui web`, including agent, terminals, file explorer, and plugins.
- **No port forwarding** — Works behind NAT, firewalls, and corporate networks.

```bash
# Authenticate with the relay
lukan login

# Check connection status
lukan relay status

# Your workstation is now accessible at your relay URL
```

## Skills

Skills are markdown instruction files that customize agent behavior per-project:

```bash
# List discovered skills
lukan skill list

# Skills live in .lukan/skills/<name>/SKILL.md
mkdir -p .lukan/skills/deploy
cat > .lukan/skills/deploy/SKILL.md << 'EOF'
---
name: Deploy
description: Deployment workflow for this project
---
# Deploy
1. Run tests first
2. Build with `make release`
3. Deploy to staging before production
EOF
```

## Workers

Schedule autonomous background tasks that run on their own:

```bash
# Create a worker interactively (set prompt, schedule, tools)
lukan worker add

# List all workers
lukan worker list

# Browse run history and view output
lukan worker runs

# Pause/resume a worker
lukan worker pause
lukan worker resume

# Start the background daemon (runs scheduled workers)
lukan daemon start

# Check daemon status
lukan daemon status
```

## Security

Lukan takes security seriously:

- **Permission Modes**: Planner (human reviews all actions), Auto (whitelisted tools run freely), Manual (approve each call)
- **Sandbox**: OS-level isolation via bubblewrap (bwrap) with configurable allowed paths
- **Sensitive File Detection**: Blocks access to `.env`, `.ssh/`, `.aws/`, credentials, and private keys by pattern
- **E2E Encryption**: Relay connections use X25519 key exchange + AES-GCM authenticated encryption
- **Plugin Isolation**: Plugins run as separate processes with declared permissions and IPC protocol

## Configuration

Config lives in `~/.config/lukan/`:

```
~/.config/lukan/
  config.json        Main configuration (provider, model, permissions)
  credentials.json   API keys and tokens (never committed)
  sessions/          Chat history
  plugins/           Installed plugins
  MEMORY.md          Persistent agent memory
```
