Quickstart: Deploy a FastAPI App

This guide will walk you through deploying a basic FastAPI application on Seenode using Uvicorn as the ASGI server.

Get started in seconds by deploying our pre-configured FastAPI template.

FastAPI Template

Deploy a minimal FastAPI application designed for zero-configuration deployment on Seenode.

Deploying an Existing FastAPI Project

Follow these steps to deploy your existing FastAPI application from a Git repository.

Prepare Your FastAPI App

Ensure your project has the necessary files for Seenode to run it.

Project Structure

Your project should have a main.py file and a requirements.txt.
- Directorymy-fastapi-app/
  - main.py
  - requirements.txt
Example main.py

Seenode will look for an app instance in your main.py file.
main.py
```
from fastapi import FastAPI

app = FastAPI()

@app.get("/")
def read_root():
    return {"message": "Hello from FastAPI"}
```
requirements.txt

Your requirements.txt should include fastapi and an ASGI server like uvicorn for production.
requirements.txt
```
fastapi
uvicorn[standard]
```
Deploy on Seenode

Follow these steps to deploy your FastAPI application:
1. From the Seenode Dashboard, create a new Web Service and connect the Git repository for your FastAPI application.
2. Seenode automatically detects a Python project. Configure the build and start commands. A common setup is:
  - Build Command: pip install -r requirements.txt
  - Start Command: uvicorn main:app --host 0.0.0.0 --port 8000
3. Choose your preferred instance size and click Create Web Service.
4. Watch your deployment progress in real-time through the Logs tab.
5. Once complete, your API will be live and accessible at your service’s public URL.

Now that your API is live, here are some recommended next steps:
