You can deploy a [Flask](https://github.com/pallets/flask) Python app on Render in just a few clicks.

This quickstart uses a simple example app. You're welcome to use your own Flask app instead.

1. Fork [render-examples/flask-hello-world](https://github.com/render-examples/flask-hello-world) on GitHub.

Here's the `app.py` file from that repo, which is borrowed from the [official Flask docs](https://flask.palletsprojects.com/quickstart/#a-minimal-application):

```python
from flask import Flask
app = Flask(__name__)

@app.route('/')
def hello_world():
       return 'Hello, World!'
```

A demo instance of this app is hosted at [flask.onrender.com](https://flask.onrender.com/). It uses [Gunicorn](https://gunicorn.org/) to serve the app in a production setting.

2. In the [Render Dashboard](https://dashboard.render.com/), click **New > Web Service** and connect your new repo.

3. Provide the following values during creation:

| Setting | Value |
| --- | --- |
| **Language** | `Python 3` |
| **Build Command** | `pip install -r requirements.txt` |
| **Start Command** | `gunicorn app:app`<br>( **Using your own app?** Instead provide whatever command Render should use to start it.) |

That's it! Your web service will be live at its `onrender.com` URL as soon as the build finishes.

Going forward, every push to your linked branch automatically builds and deploys your app. If a build fails, Render cancels the deploy, and your app's existing version continues running until the next successful deploy. [Learn more about deploys](/content/docs/deploys/index.html).

If you need to use a specific version of Python for your app, see [Setting Your Python Version](/content/docs/python-version/index.html).
