# 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]
|
|
To use the offline chat model with your GPU, we recommend using the Docker setup with Ollama . You can also use the local Khoj setup via the Python package directly.
|
|
:::
|
|
|
|
:::info[First Run]
|
|
Restart your Khoj server after the first run to ensure all settings are applied correctly.

|
<h3>Prerequisites</h3>
|
|
<h4>Docker</h4>
|
|
- *Option 1*: Click here to install [Docker Desktop](https://docs.docker.com/desktop/install/mac-install/). Make sure you also install the [Docker Compose](https://docs.docker.com/desktop/install/mac-install/) tool.
|
|
|
|
- *Option 2*: Use [Homebrew](https://brew.sh/) to install Docker and Docker Compose.
|
|
```shell
|
|
brew install --cask docker
|
|
brew install docker-compose
|
|
```
|
|
<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
|
|
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 commercial chat models respectively.
|
|
- Uncomment `OPENAI_API_BASE` to use [Ollama](/advanced/ollama?type=first-run&server=docker#setup) running on your host machine. Or set it to the URL of your OpenAI compatible API like vLLM or [LMStudio](/advanced/lmstudio).
|
|
3. Start Khoj by running the following command in the same directory as your docker-compose.yml file.
|
|
```shell
|
|
cd ~/.khoj
|
|
docker-compose up
|
|
```

<h3>1. Install Postgres (with PgVector)</h3>
|
|
|
|
Khoj uses Postgres DB for all server configuration and to scale to multi-user setups. It uses the pgvector package in Postgres to manage your document embeddings. Both Postgres and pgvector need to be installed for Khoj to work.
|

<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`)

## 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.

1. Create a new [AI Model Api](http://localhost:42110/server/admin/database/aimodelapi/add) in the server admin settings.
|
|
- Add your [OpenAI API key](https://platform.openai.com/api-keys)

- (Optional) Set the API base URL. It is only relevant if you're using another OpenAI-compatible proxy server like [Ollama](/advanced/ollama) or [LMStudio](/advanced/lmstudio).<br />
|
|
|
|
2. Create a new [chat model](http://localhost:42110/server/admin/database/chatmodel/add)

|
|
- Make sure to set the `model-type` field to `OpenAI`.
|
|
- If your model supports vision, set the `vision enabled` field to `true`. This is currently only supported for OpenAI models with vision capabilities.

### 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
|
|
```
|
|

|
|
|
|
#### Khoj in Docker errors out with \"Killed\" in error message
|
|
- **Fix**: Increase RAM available to Docker Containers in Docker Settings
