<!-- The video is listed in the root Readme.md of the repo -->

<!--We also offer this in video format. You can check it out [here](https://github.com/Significant-Gravitas/AutoGPT?tab=readme-ov-file#how-to-setup-for-self-hosting). -->

!!! warning
    **DO NOT FOLLOW ANY OUTSIDE TUTORIALS AS THEY WILL LIKELY BE OUT OF DATE**

## Prerequisites

To setup the server, you need to have the following installed:

- [Node.js](https://nodejs.org/en/)
- [Docker](https://docs.docker.com/get-docker/)
- [Git](https://git-scm.com/downloads)

### Checking if you have Node.js & NPM installed

We use Node.js to run our frontend application.

If you need assistance installing Node.js:
https://nodejs.org/en/download/

NPM is included with Node.js, but if you need assistance installing NPM:
https://docs.npmjs.com/downloading-and-installing-node-js-and-npm

You can check if you have Node.js & NPM installed by running the following command:

```bash
node -v
npm -v
```

Once you have Node.js installed, you can proceed to the next step.

### Checking if you have Docker & Docker Compose installed

Docker containerizes applications, while Docker Compose orchestrates multi-container Docker applications.

If you need assistance installing docker:
https://docs.docker.com/desktop/

Docker-compose is included in Docker Desktop, but if you need assistance installing docker compose: 
https://docs.docker.com/compose/install/

You can check if you have Docker installed by running the following command:

```bash
docker -v
docker compose -v
```

Once you have Docker and Docker Compose installed, you can proceed to the next step.

 Raspberry Pi 5 Specific Notes
 </summary>
    On Raspberry Pi 5 with Raspberry Pi OS, the default 16K page size will cause issues with the <code>supabase-vector</code> container (expected: 4K).
    </br>
    To fix this, edit <code>/boot/firmware/config.txt</code> and add:
    </br>
    ```ini
    kernel=kernel8.img
    ```
    Then reboot. You can check your page size with:
    </br>
    ```bash
    getconf PAGESIZE
    ```
    <code>16384</code> means 16K (incorrect), and <code>4096</code> means 4K (correct).
    After adjusting, <code>docker compose up -d --build</code> should work normally.
    </br>
    See <a href="https://github.com/supabase/supabase/issues/33816">supabase/supabase #33816</a> for additional context.
</details>

## Setup

### Cloning the Repository
The first step is cloning the AutoGPT repository to your computer.
To do this, open a terminal window in a folder on your computer and run:
```
git clone https://github.com/Significant-Gravitas/AutoGPT.git
```
If you get stuck, follow [this guide](https://docs.github.com/en/repositories/creating-and-managing-repositories/cloning-a-repository).

Once that's complete you can continue the setup process.

### Running the backend services

To run the backend services, follow these steps:

* Navigate to the `autogpt_platform` directory inside the AutoGPT folder:
  ```bash
   cd AutoGPT/autogpt_platform
  ```

* Copy the `.env.example` file to `.env` in `autogpt_platform`:
  ```
   cp .env.example .env
  ```
  This command will copy the `.env.example` file to `.env` in the `supabase` directory. You can modify the `.env` file to add your own environment variables.

* Run the backend services:
  ```
   docker compose up -d --build
  ```
  This command will start all the necessary backend services defined in the `docker-compose.combined.yml` file in detached mode.


### Running the frontend application

To run the frontend application open a new terminal and follow these steps:

- Navigate to `frontend` folder within the `autogpt_platform` directory:

  ```
   cd frontend
  ```

- Copy the `.env.example` file available in the `frontend` directory to `.env` in the same directory:

  ```
   cp .env.example .env
  ```

  You can modify the `.env` within this folder to add your own environment variables for the frontend application.

- Run the following command:
  ```
   corepack enable
   pnpm install
   pnpm dev
  ```
  This command will enable corepack, install the necessary dependencies with pnpm, and start the frontend application in development mode.

### Checking if the application is running

You can check if the server is running by visiting [http://localhost:3000](http://localhost:3000) in your browser.

**Notes:**
 
By default the application for different services run on the following ports: 

Frontend UI Server: 3000
Backend Websocket Server: 8001
Execution API Rest Server: 8006

### Additional Notes

You may want to change your encryption key in the `.env` file in the `autogpt_platform/backend` directory.

To generate a new encryption key, run the following command in python:

```python
from cryptography.fernet import Fernet;Fernet.generate_key().decode()
```

Or run the following command in the `autogpt_platform/backend` directory:

```bash
poetry run cli gen-encrypt-key
```

Then, replace the existing key in the `autogpt_platform/backend/.env` file with the new one.

<summary><strong>Alternate Steps</strong></summary>

#### AutoGPT Agent Server (OLD)
This is an initial project for creating the next generation of agent execution, which is an AutoGPT agent server.
The agent server will enable the creation of composite multi-agent systems that utilize AutoGPT agents and other non-agent components as its primitives.

##### Docs

You can access the docs for the [AutoGPT Agent Server here](https://docs.agpt.co/#1-autogpt-server).

##### Setup

We use the Poetry to manage the dependencies. To set up the project, follow these steps inside this directory:

0. Install Poetry

```sh
pip install poetry
```
  
1. Configure Poetry to use .venv in your project directory

```sh
  poetry config virtualenvs.in-project true
```

2. Enter the poetry shell

```sh
poetry shell
```

3. Install dependencies

```sh
poetry install
```

4. Copy .env.example to .env

```sh
cp .env.example .env
```

5. Generate the Prisma client

```sh
poetry run prisma generate
```

> In case Prisma generates the client for the global Python installation instead of the virtual environment, the current mitigation is to just uninstall the global Prisma package:
>
> ```sh
> pip uninstall prisma
> ```
>
> Then run the generation again. The path *should* look something like this:  
> `<some path>/pypoetry/virtualenvs/backend-TQIRSwR6-py3.12/bin/prisma`

6. Migrate the database. Be careful because this deletes current data in the database.

```sh
docker compose up db -d
poetry run prisma migrate deploy
```

### Starting the AutoGPT server without Docker

To run the server locally, start in the autogpt_platform folder:

```sh
cd ..
```

Run the following command to run database in docker but the application locally:

```sh
docker compose --profile local up deps --build --detach
cd backend
poetry run app
```

### Starting the AutoGPT server with Docker

Run the following command to build the dockerfiles:

```sh
docker compose build
```

Run the following command to run the app:

```sh
docker compose up
```

Run the following to automatically rebuild when code changes, in another terminal:

```sh
docker compose watch
```

Run the following command to shut down:

```sh
docker compose down
```

If you run into issues with dangling orphans, try:

```sh
docker compose down --volumes --remove-orphans && docker-compose up --force-recreate --renew-anon-volumes --remove-orphans  
```

### 📌 Windows Installation Note

When installing Docker on Windows, it is **highly recommended** to select **WSL 2** instead of Hyper-V. Using Hyper-V can cause compatibility issues with Supabase, leading to the `supabase-db` container being marked as **unhealthy**.

#### **Steps to enable WSL 2 for Docker:**
1. Install [WSL 2](https://learn.microsoft.com/en-us/windows/wsl/install).
2. Ensure that your Docker settings use WSL 2 as the default backend:
  - Open **Docker Desktop**.
  - Navigate to **Settings > General**.
  - Check **Use the WSL 2 based engine**.
3. Restart **Docker Desktop**.

#### **Already Installed Docker with Hyper-V?**
If you initially installed Docker with Hyper-V, you **don’t need to reinstall** it. You can switch to WSL 2 by following these steps:
1. Open **Docker Desktop**.
2. Go to **Settings > General**.
3. Enable **Use the WSL 2 based engine**.
4. Restart Docker.

🚨 **Warning:** Enabling WSL 2 may **erase your existing containers and build history**. If you have important containers, consider backing them up before switching.

For more details, refer to [Docker's official documentation](https://docs.docker.com/desktop/windows/wsl/).


## Development

### Formatting & Linting
Auto formatter and linter are set up in the project. To run them:

Install:
```sh
poetry install --with dev
```

Format the code:
```sh
poetry run format
```

Lint the code:
```sh
poetry run lint
```

### Testing

To run the tests:

```sh
poetry run test
```

To update stored snapshots after intentional API changes:

```sh
pytest --snapshot-update
```

## Project Outline

The current project has the following main modules:

#### **blocks**

This module stores all the Agent Blocks, which are reusable components to build a graph that represents the agent's behavior.

#### **data**

This module stores the logical model that is persisted in the database.
It abstracts the database operations into functions that can be called by the service layer.
Any code that interacts with Prisma objects or the database should reside in this module.
The main models are:
* `block`: anything related to the block used in the graph
* `execution`: anything related to the execution graph execution
* `graph`: anything related to the graph, node, and its relations

#### **execution**

This module stores the business logic of executing the graph.
It currently has the following main modules:
* `manager`: A service that consumes the queue of the graph execution and executes the graph. It contains both pieces of logic.
* `scheduler`: A service that triggers scheduled graph execution based on a cron expression. It pushes an execution request to the manager.

#### **server**

This module stores the logic for the server API.
It contains all the logic used for the API that allows the client to create, execute, and monitor the graph and its execution.
This API service interacts with other services like those defined in `manager` and `scheduler`.

#### **utils**

This module stores utility functions that are used across the project.
Currently, it has two main modules:
* `process`: A module that contains the logic to spawn a new process.
* `service`: A module that serves as a parent class for all the services in the project.

## Service Communication

Currently, there are only 3 active services:

- AgentServer (the API, defined in `server.py`)
- ExecutionManager (the executor, defined in `manager.py`)
- Scheduler (the scheduler, defined in `scheduler.py`)

The services run in independent Python processes and communicate through an IPC.
A communication layer (`service.py`) is created to decouple the communication library from the implementation.

Currently, the IPC is done using Pyro5 and abstracted in a way that allows a function decorated with `@expose` to be called from a different process.

## Adding a New Agent Block

To add a new agent block, you need to create a new class that inherits from `Block` and provides the following information:
* All the block code should live in the `blocks` (`backend.blocks`) module.
* `input_schema`: the schema of the input data, represented by a Pydantic object.
* `output_schema`: the schema of the output data, represented by a Pydantic object.
* `run` method: the main logic of the block.
* `test_input` & `test_output`: the sample input and output data for the block, which will be used to auto-test the block.
* You can mock the functions declared in the block using the `test_mock` field for your unit tests.
* Once you finish creating the block, you can test it by running `poetry run pytest -s test/block/test_block.py`.
