# Python Quickstart

Use a [Web Service](/docs/services/web-services) for a Python HTTP application. The runtime command must bind to the port supplied in `PORT`.

## Create a Flask application

Create `app.py`:

```python
import os
from flask import Flask

app = Flask(__name__)

@app.get("/")
def home():
    return "Hello from NexHost"

@app.get("/health")
def health():
    return {"ok": True}

if __name__ == "__main__":
    app.run(host="0.0.0.0", port=int(os.environ["PORT"]))
```

Create `requirements.txt`:

```text
Flask
gunicorn
```

## Configure the service

1. Select **Web Service** in **New Project**.
2. Connect the repository or archive containing `app.py` and `requirements.txt`.
3. Set **Build command** to `pip install -r requirements.txt`.
4. Set **Start command** to `gunicorn app:app --bind 0.0.0.0:$PORT`.
5. Set **Health path** to `/health`, then deploy.

For FastAPI, use a comparable `uvicorn` start command that sets `--host 0.0.0.0` and `--port $PORT`.
