+description: 'Deploy your RAG application to fly.io platform'
+---
+
+Embedchain has a nice and simple abstraction on top of the [Fly.io](https://fly.io/) tools to let developers deploy RAG application to fly.io platform seamlessly. 
+
+Follow the instructions given below to deploy your first application quickly:
+
+
+## Step-1: Install flyctl command line
+
+<CodeGroup>
+```bash OSX
+brew install flyctl
+```
+
+```bash Linux
+curl -L https://fly.io/install.sh | sh
+```
+
+```bash Windows
+pwsh -Command "iwr https://fly.io/install.ps1 -useb | iex"
+```
+</CodeGroup>
+
+Once you have installed the fly.io cli tool, signup/login to their platform using the following command:
+
+<CodeGroup>
+```bash Sign up
+fly auth signup
+```
+
+```bash Sign in
+fly auth login
+```
+</CodeGroup>
+
+In case you run into issues, refer to official [fly.io docs](https://fly.io/docs/hands-on/install-flyctl/).
+
+## Step-2: Create RAG app
+
+We provide a command line utility called `ec` that inherits the template for `fly.io` platform and help you deploy the app. Follow the instructions to create a fly.io app using the template provided:
+
+```bash Create application
+mkdir my-rag-app
+ec create --template=fly.io
+```
+
+This will generate a directory structure like this:
+
+```bash
+├── Dockerfile
+├── app.py
+├── fly.toml
+├── .env
+├── .env.example
+└── requirements.txt
+```
+
+Feel free to edit the files as required.
+- `Dockerfile`: Defines the steps to setup the application
+- `app.py`: Contains FastAPI app code
+- `fly.toml`: fly.io config file
+- `.env`: Contains environment variables for production
+- `.env.example`: Contains dummy environment variables (can ignore this file)
+- `requirements.txt`: Contains python dependencies for your FastAPI application
+
+## Step-3: Test app locally
+
+You can run the app locally by simply doing:
+
+```bash Run locally
+pip install -r requirements.txt
+ec dev
+```
+
+## Step-4: Deploy to fly.io
+
+You can deploy to fly.io using the following command:
+```bash Deploy app
+ec deploy
+```
+
+Once this step finished, it will provide you with the deployment endpoint where you can access the app live. It will look something like this:
+
+You can also check the logs, monitor app status etc on their dashboard by running command `fly dashboard`.

+## Deploy on Embedchain Platform
 
 Embedchain enables developers to deploy their LLM-powered apps in production using the [Embedchain platform](https://app.embedchain.ai). The platform offers free access to context on your data through its REST API. Once the pipeline is deployed, you can update your data sources anytime after deployment.

 You can also deploy Embedchain as a self-hosted service using the dockerized REST API service that we provide. Please follow the [guide here](/examples/rest-api) on how to use the REST API service. Here are some tutorials on how to deploy a containerized application to different platforms like AWS, GCP, Azure etc:
