- **Own your stack**: inspect, customize, self-host, and extend without a giant platform.

## 📦 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`.

Pick **one** install method:

Prerequisites: Python 3.11 or newer. Git is only needed for a source install; Node.js/Bun are only needed if you are developing the WebUI itself.

If terminals, API keys, or config files are new to you, use the guided zero-background walkthrough in [Start Without Technical Background](./docs/start-without-technical-background.md) instead of this compact README path.

**One-command setup**

macOS / Linux:

```bash
curl -fsSL https://raw.githubusercontent.com/HKUDS/nanobot/main/scripts/install.sh | sh
```

Windows PowerShell:

```powershell
irm https://raw.githubusercontent.com/HKUDS/nanobot/main/scripts/install.ps1 | iex
```

The default command installs or upgrades `nanobot-ai` from PyPI, then starts `nanobot onboard --wizard`. It avoids system-wide pip installs by using an active virtual environment, `uv`, `pipx`, or a managed venv under `~/.nanobot/venv`. If Quick Start finishes, skip the manual initialize/configure steps below and go straight to **Open the WebUI**.

To preview the plan without changing your environment, pass `--dry-run`; combine it with `--dev` when you want to preview the main-branch install.

```bash
curl -fsSL https://raw.githubusercontent.com/HKUDS/nanobot/main/scripts/install.sh | sh -s -- --dry-run
```

```powershell
& ([scriptblock]::Create((irm https://raw.githubusercontent.com/HKUDS/nanobot/main/scripts/install.ps1))) --dry-run
```

To install the current `main` branch instead, pass `--dev`:

```bash
curl -fsSL https://raw.githubusercontent.com/HKUDS/nanobot/main/scripts/install.sh | sh -s -- --dev
```

```powershell
& ([scriptblock]::Create((irm https://raw.githubusercontent.com/HKUDS/nanobot/main/scripts/install.ps1))) --dev
```

If you prefer to inspect the script first, open [`scripts/install.sh`](./scripts/install.sh) or [`scripts/install.ps1`](./scripts/install.ps1).

**Install with `uv`**

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

**Install from PyPI with pip**

```bash
python -m pip install nanobot-ai
```

If pip reports `externally-managed-environment` on macOS or Linux, use the one-command installer, `uv tool install nanobot-ai`, `pipx install nanobot-ai`, or install inside a virtual environment.

**Install from source**

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

Verify the install:

```bash
nanobot --version
```

## 🚀 Quick Start

**1. Initialize**

Skip this step if the one-command setup already started the wizard and Quick Start finished there.

```bash
nanobot onboard
```

Use `nanobot onboard --wizard` if you prefer an interactive setup.

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

Skip this step if you already configured provider and model settings in the wizard.

`nanobot onboard` creates `~/.nanobot/config.json` and `~/.nanobot/workspace/`. Configure these **two parts** in the config file. Add or merge the following blocks into the existing file instead of replacing the whole file.

The example below uses a generic OpenAI-compatible `custom` provider so the compact path does not recommend one hosted service. Provider examples are recipes, not rankings or endorsements. For copyable provider-specific setup, see [Provider Cookbook](./docs/provider-cookbook.md).

*Set your API key*:

```json
{
  "providers": {
    "custom": {
      "apiKey": "your-api-key",
      "apiBase": "https://api.example.com/v1"
    }
  }
}
```

*Set a model preset and make it active*:

```json
{
  "modelPresets": {
    "primary": {
      "label": "Primary",
      "provider": "custom",
      "model": "model-id-from-your-provider",
      "maxTokens": 8192,
      "contextWindowTokens": 200000,
      "temperature": 0.1
    }
  },
  "agents": {
    "defaults": {
      "modelPreset": "primary"
    }
  }
}
```

Direct `agents.defaults.provider` and `agents.defaults.model` still work for existing configs, but named presets are the recommended path because they also power `/model` switching and `fallbackModels`.

For another provider, the same config shape still applies:

| Replace | Where |
|---|---|
| Provider config key | `providers.<provider>` |
| API key | `providers.<provider>.apiKey` |
| Preset provider name | `modelPresets.primary.provider` |
| Model ID | `modelPresets.primary.model` |
| Endpoint URL, only when needed | `providers.<provider>.apiBase` |

**3. Open the WebUI**

Start the browser workbench:

```bash
nanobot webui
```

`nanobot webui` prepares the local WebSocket channel if needed, starts the gateway, and opens `http://127.0.0.1:8765`. It binds the first-run WebUI to `127.0.0.1` by default, so it is not exposed to your LAN. Prefer not to keep a terminal open? Use `nanobot webui --background`, then manage the gateway with `nanobot gateway status`, `logs`, `restart`, and `stop`.

For manual or terminal-only setup, test one CLI message:

```bash
nanobot status
nanobot agent -m "Hello!"
```

In `nanobot status`, it is normal for most providers to say `not set`. The active preset's provider should be configured, and `Config` plus `Workspace` should show check marks.

If that works, start an interactive chat:

```bash
nanobot agent
```

## 🌐 WebUI

The WebUI ships **inside the published wheel** — no extra build step. It is the browser workbench for chat sessions, workspace controls, Apps, Skills, Automations, and settings. For the full user guide, see [`docs/webui.md`](./docs/webui.md).

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

**Open it**

```bash
nanobot webui
```

The command enables the local WebSocket channel after confirmation, starts the gateway, and opens [`http://127.0.0.1:8765`](http://127.0.0.1:8765). To open it from another device on your LAN, see [WebUI docs -> LAN access](./docs/webui.md#lan-access).

The WebUI is served by the WebSocket channel on port `8765` by default. The gateway's `18790` port is for the health endpoint, not the browser UI.

> [!TIP]
> Working on the WebUI itself? Check out [`webui/README.md`](./webui/README.md) for the source-tree, Vite dev server, build, and test workflow.

## 🏗️ 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.
