Deploy FastAPI App on Seenode | FastAPI Hosting & Deployment Guide

This guide will walk you through deploying your existing FastAPI application on seenode using Uvicorn as the ASGI server.

Prerequisites

Before you begin, ensure you have:

Ensure your project has a main.py file and a requirements.txt. seenode will look for an app instance in your main.py file.

from fastapi import FastAPI

app = FastAPI()

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

Your requirements.txt should include fastapi and an ASGI server like uvicorn for production:

fastapi
uvicorn[standard]

Push to Git
Commit your project and push it to GitHub or GitLab.
Create a Web Service
From the
seenode Dashboard
, create a new Web Service and connect the Git repository for your FastAPI application.
Configure Build & Start
seenode automatically detects a Python project. Configure:
- Build Command:
```
pip install -r requirements.txt
```
- Start Command:
```
uvicorn main:app --host 0.0.0.0 --port 80
```
The Port field starts empty—set it during setup to the value your app uses (for example, 80). Ensure your application binds to the same port (for example, --port 80). Do not rely on a PORT environment variable; seenode routes using the configured Port input.
Choose Pricing Tier
Select your preferred instance size and click Create Web Service.
Deploy
Click Create Web Service and watch logs until your web service is live.
Success
Once complete, your API is live and accessible at your service’s public URL.
