# Self-Host
Learn about how to self-host Khoj on your own machine.

Benefits to self-hosting:
1. **Privacy**: Your data will never have to leave your private network. You can even use Khoj without an internet connection if deployed on your personal computer.
2. **Customization**: You can customize Khoj to your liking, from models, to host URL, to feature enablement.

```mdx-code-block
import Tabs from '@theme/Tabs';
import TabItem from '@theme/TabItem';
```

## Setup Khoj
These are the general setup instructions for self-hosted Khoj.
You can install the Khoj server using either [Docker](?server=docker) or [Pip](?server=pip).

:::info[Offline Model + GPU]
If you want to use the offline chat model and you have a GPU, you should use Installation Option 2  - local setup via the Python package directly. Our Docker image doesn't currently support running the offline chat model on GPU, making inference times really slow.

        <h3>Prerequisites</h3>
        Install [Docker Desktop](https://docs.docker.com/desktop/install/mac-install/)
      </TabItem>
      <TabItem value="windows" label="Windows">
      <h3>Prerequisites</h3>
      1. Install [WSL2](https://learn.microsoft.com/en-us/windows/wsl/install) and restart your machine
         ```shell
         # Run in PowerShell
         wsl --install
         ```
      2. Install [Docker Desktop](https://docs.docker.com/desktop/install/windows-install/) with **[WSL2 backend](https://docs.docker.com/desktop/wsl/#turn-on-docker-desktop-wsl-2)** (default)
      </TabItem>
      <TabItem value="linux" label="Linux">
        <h3>Prerequisites</h3>
        Install [Docker Desktop](https://docs.docker.com/desktop/install/linux/).
        You can also use your package manager to install Docker Engine & Docker Compose.
      </TabItem>
    </Tabs>

<h3>Setup</h3>
1. Download the Khoj docker-compose.yml file [from Github](https://github.com/khoj-ai/khoj/blob/master/docker-compose.yml)
   ```shell
   # Windows users should use their WSL2 terminal to run these commands
   mkdir ~/.khoj && cd ~/.khoj
   wget https://raw.githubusercontent.com/khoj-ai/khoj/master/docker-compose.yml
   ```
2. Configure the environment variables in the docker-compose.yml
   - Set `KHOJ_ADMIN_PASSWORD`, `KHOJ_DJANGO_SECRET_KEY` (and optionally the `KHOJ_ADMIN_EMAIL`) to something secure. This allows you to customize Khoj later via the admin panel.
   - Set `OPENAI_API_KEY`, `ANTHROPIC_API_KEY`, or `GEMINI_API_KEY` to your API key if you want to use OpenAI, Anthropic or Gemini chat models respectively.
3. Start Khoj by running the following command in the same directory as your docker-compose.yml file.
   ```shell
   # Windows users should use their WSL2 terminal to run these commands
   cd ~/.khoj
   docker-compose up
   ```

:::info[Remote Access]
By default Khoj is only accessible on the machine it is running. To access Khoj from a remote machine see [Remote Access Docs](/advanced/remote).
:::

Your setup is complete once you see `🌖 Khoj is ready to use` in the server logs on your terminal.

<h3>4. Start Khoj Server</h3>

Run the following command from your terminal to start the Khoj service.

```shell
khoj --anonymous-mode
```
`--anonymous-mode` allows access to Khoj without requiring login. This is usually fine for local only, single user setups. If you need authentication follow the [authentication setup docs](/advanced/authentication).

<h4>First Run</h4>
On the first run of the above command, you will be prompted to:
1. Create an admin account with a email and secure password
2. Customize the chat models to enable
   - Keep your [OpenAI](https://platform.openai.com/api-keys), [Anthropic](https://console.anthropic.com/account/keys), [Gemini](https://aistudio.google.com/app/apikey) API keys and [OpenAI](https://platform.openai.com/docs/models), [Anthropic](https://docs.anthropic.com/en/docs/about-claude/models#model-names), [Gemini](https://cloud.google.com/vertex-ai/generative-ai/docs/learn/models#gemini-models), [Offline](https://huggingface.co/models?pipeline_tag=text-generation&library=gguf) chat model names handy to set any of them up during first run.
3. Your setup is complete once you see `🌖 Khoj is ready to use` in the server logs on your terminal!


:::tip[Auto Start]
To start Khoj automatically in the background use [Task scheduler](https://www.windowscentral.com/how-create-automated-task-using-task-scheduler-windows-10) on Windows or [Cron](https://en.wikipedia.org/wiki/Cron) on Mac, Linux (e.g. with `@reboot khoj`)

  </TabItem>
</Tabs>

## Use Khoj

You can now open the web app at http://localhost:42110 and start interacting!<br />
Nothing else is necessary, but you can customize your setup further by following the steps below.

:::info[First Message to Offline Chat Model]
The offline chat model gets downloaded when you first send a message to it. The download can take a few minutes! Subsequent messages should be faster.
:::

### Add Chat Models
<h4>Login to the Khoj Admin Panel</h4>
Go to http://localhost:42110/server/admin and login with the admin credentials you setup during installation.

:::info[CSRF Error]
Ensure you are using **localhost, not 127.0.0.1**, to access the admin panel to avoid the CSRF error.
:::

:::info[DISALLOWED HOST or Bad Request (400) Error]
You may hit this if you try access Khoj exposed on a custom domain (e.g. 192.168.12.3 or example.com) or over HTTP.
Set the environment variables KHOJ_DOMAIN=your-domain and KHOJ_NO_HTTPS=True if required to avoid this error.
:::

:::tip[Note]
Using Safari on Mac? You might not be able to login to the admin panel. Try using Chrome or Firefox instead.
:::

<h4>Configure Chat Model</h4>
Setup which chat model you'd want to use. Khoj supports local and online chat models.

### Sync your Knowledge

- You can chat with your notes and documents using Khoj.
- Khoj can keep your files and folders synced using the Khoj [Desktop](/clients/desktop#setup), [Obsidian](/clients/obsidian#setup) or [Emacs](/clients/emacs#setup) clients.
- Your [Notion workspace](/data-sources/notion_integration) can be directly synced from the web app.
- You can also just drag and drop specific files you want to chat with on the [Web app](/clients/web#upload-documents).

### Setup Khoj Clients
The Khoj web app is available by default to chat, search and configure Khoj.<br />
You can also install a Khoj client to easily access it from Obsidian, Emacs, Whatsapp or your OS and keep your documents synced with Khoj.

:::info[Note]
Set the host URL on your clients settings page to your Khoj server URL. By default, use `http://127.0.0.1:42110` or `http://localhost:42110`. Note that `localhost` may not work in all cases.

## Troubleshoot

#### Dependency conflict when trying to install Khoj python package with pip
- **Reason**: When conflicting dependency versions are required by Khoj vs other python packages installed on your system
- **Fix**: Install Khoj in a python virtual environment using [venv](https://docs.python.org/3/library/venv.html) or [pipx](https://pypa.github.io/pipx) to avoid this dependency conflicts
- **Process**:
  1. Install [pipx](https://pypa.github.io/pipx/#install-pipx)
  2. Use `pipx` to install Khoj to avoid dependency conflicts with other python packages.
     ```shell
     pipx install khoj
     ```
  3. Now start `khoj` using the standard steps described earlier

#### Install fails while building Tokenizer dependency
- **Details**: `pip install khoj` fails while building the `tokenizers` dependency. Complains about Rust.
- **Fix**: Install Rust to build the tokenizers package. For example on Mac run:
    ```shell
    brew install rustup
    rustup-init
    source ~/.cargo/env
    ```
- **Refer**: [Issue with Fix](https://github.com/khoj-ai/khoj/issues/82#issuecomment-1241890946) for more details

#### Khoj in Docker errors out with \"Killed\" in error message
- **Fix**: Increase RAM available to Docker Containers in Docker Settings
- **Refer**: [StackOverflow Solution](https://stackoverflow.com/a/50770267), [Configure Resources on Docker for Mac](https://docs.docker.com/desktop/mac/#resources)
