🐈 **nanobot** is an open-source and ultra-lightweight AI agent in the spirit of [OpenClaw](https://github.com/openclaw/openclaw), [Claude Code](https://www.anthropic.com/claude-code), and [Codex](https://www.openai.com/codex/). It keeps the core agent loop small and readable while still supporting chat channels, memory, MCP and practical deployment paths, so you can go from local setup to a long-running personal agent with minimal overhead.

## 💡 Key Features of nanobot

- **Ultra-lightweight**: stable long-running agent behavior with a small, readable core.
- **Research-ready**: the codebase is intentionally simple enough to study, modify, and extend.
- **Practical**: chat channels, API, memory, MCP, and deployment paths are already built in.
- **Hackable**: you can start fast, then go deeper through repo docs instead of a monolithic landing page.

## 📦 Install

> [!IMPORTANT]
> If you want the newest features and experiments, install from source. 
> 
> If you want the most stable day-to-day experience, install from PyPI or with `uv`.

**Install from source**

```bash
git clone https://github.com/HKUDS/nanobot.git
cd nanobot
pip install -e .
```

**Install with `uv`**

```bash
uv tool install nanobot-ai
```

**Install from PyPI**

```bash
pip install nanobot-ai
```

## 🚀 Quick Start

**1. Initialize**

```bash
nanobot onboard
```

**2. Configure** (`~/.nanobot/config.json`)

Configure these **two parts** in your config (other options have defaults). Add or merge the following blocks into your existing config instead of replacing the whole file.

*Set your API key* (e.g. [OpenRouter](https://openrouter.ai/keys), recommended for global users):

```json
{
  "providers": {
    "openrouter": {
      "apiKey": "sk-or-v1-xxx"
    }
  }
}
```

*Set your model* (optionally pin a provider — defaults to auto-detection):

```json
{
  "agents": {
    "defaults": {
      "provider": "openrouter",
      "model": "anthropic/claude-opus-4-6"
    }
  }
}
```

**3. Chat**

```bash
nanobot agent
```


- Want different LLM providers, web search, MCP, security settings, or more config options? See [Configuration](./docs/configuration.md)
- Want to run nanobot in chat apps like Telegram, Discord, WeChat or Feishu? See [Chat Apps](./docs/chat-apps.md)
- Want Docker or Linux service deployment? See [Deployment](./docs/deployment.md)

## 🧪 WebUI (Development)

> [!NOTE]
> The WebUI development workflow currently requires a source checkout and is not yet shipped together with the official packaged release. See [WebUI Document](./webui/README.md) for full WebUI development docs and build steps.

<p align="center">
  <img src="images/nanobot_webui.png" alt="nanobot webui preview" width="900">
</p>

**1. Enable the WebSocket channel in `~/.nanobot/config.json`**

```json
{ "channels": { "websocket": { "enabled": true } } }
```

**2. Start the gateway**

```bash
nanobot gateway
```

**3. Start the webui dev server**

```bash
cd webui
bun install
bun run dev
```

## 🏗️ Architecture

<p align="center">
  <img src="images/nanobot_arch.png" alt="nanobot architecture" width="800">
</p>

🐈 nanobot stays lightweight by centering everything around a small agent loop: messages come in from chat apps, the LLM decides when tools are needed, and memory or skills are pulled in only as context instead of becoming a heavy orchestration layer. That keeps the core path readable and easy to extend, while still letting you add channels, tools, memory, and deployment options without turning the system into a monolith.
