Nanobot

🐈 nanobot is an open-source and ultra-lightweight AI agent in the spirit of OpenClaw, Claude Code, and 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

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

Install with uv

uv tool install nanobot-ai

Install from PyPI

pip install nanobot-ai

🚀 Quick Start

1. Initialize

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, recommended for global users):

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

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

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

3. Chat

nanobot agent

• Want different LLM providers, web search, MCP, security settings, or more config options? See Configuration
• Want to run nanobot in chat apps like Telegram, Discord, WeChat or Feishu? See Chat Apps
• Want Docker or Linux service deployment? See Deployment

🧪 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 for full WebUI development docs and build steps.

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

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

2. Start the gateway

nanobot gateway

3. Start the webui dev server

cd webui
bun install
bun run dev

🏗️ Architecture

🐈 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.
