+description: 'Deploy your RAG application to railway.app'
+---
+
+It's easy to host your Embedchain-powered apps and APIs on railway.
+
+Follow the instructions given below to deploy your first application quickly:
+
+## Step-1: Create RAG app
+
+```bash Install embedchain
+pip install embedchain
+```
+
+<Tip>
+**Create a full stack app using Embedchain CLI**
+
+To use your hosted embedchain RAG app, you can easily set up a FastAPI server that can be used anywhere.
+To easily set up a FastAPI server, check out [Get started with Full stack](https://docs.embedchain.ai/get-started/full-stack) page.
+
+Hosting this server on railway is super easy!
+
+</Tip>
+
+## Step-2: Set up your project
+
+### With Docker
+
+You can create a `Dockerfile` in the root of the project, with all the instructions. However, this method is sometimes slower in deployment.
+
+### Without Docker
+
+By default, Railway uses Python 3.7. Embedchain requires the python version to be >3.9 in order to install.
+
+To fix this, create a `.python-version` file in the root directory of your project and specify the correct version
+
+```bash .python-version
+3.10
+```
+
+You also need to create a `requirements.txt` file to specify the requirements.
+
+```bash requirements.txt
+python-dotenv
+embedchain
+fastapi==0.108.0
+uvicorn==0.25.0
+embedchain
+beautifulsoup4
+sentence-transformers
+```
+
+## Step-3: Deploy to Railway 🚀
+
+1. Go to https://railway.app and create an account.
+2. Create a project by clicking on the "Start a new project" button
+
+### With Github
+
+Select `Empty Project` or `Deploy from Github Repo`. 
+
+You should be all set!
+
+### Without Github
+
+You can also use the railway CLI to deploy your apps from the terminal, if you don't want to connect a git repository.
+
+To do this, just run this command in your terminal
+
+```bash Install and set up railway CLI
+npm i -g @railway/cli
+railway login
+railway link [projectID]
+```
+
+Finally, run `railway up` to deploy your app.
+```bash Deploy
+railway up
+```
