How to Run Host FastAPI for Free: A Step-by-Step Guide

How to Run Host FastAPI for Free: A Step-by-Step Guide

Okay, so your buddy told you about this thing called FastAPI and you’re like “What’s that? Some kind of fast food?” No, my friend, it’s like a super cool way to make websites and apps really quick. But wait! You don’t wanna spend all your allowance on hosting, right? So here’s the scoop on how to host your FastAPI app for free. Get ready for a giggle ride!

Step 1: Sign Up for an Account

First things first. You gotta sign up for a platform that lets you host stuff for free. There are so many out there but let’s pick one like Heroku or Railway. Seriously, just go to their website and click that big ol’ sign-up button. It’s like signing up for a pizza delivery but you don’t get any pizza!

But then, you have to check your email because they’ll send you some magic link or something. Click it! And boom—you’re in!

Step 2: Set Up Your Environment

So now that you’re signed up and probably thinking about pizza again, it’s time to set up your environment. This is where all the magic happens, kinda like a wizard needs a wand.

Just open your terminal or command prompt thingy and type “pip install fastapi uvicorn” with all the confidence of someone who knows what they’re doing. Like you’re ordering at a restaurant and know exactly what you want—“I want the FastAPI dish with a side of Uvicorn please!”

Step 3: Create Your Awesome App

Now you gotta create your app! Just grab any code editor (like Notepad but cooler) and make a new file called main.py. Type this in:

from fastapi import FastAPI

app = FastAPI()

@app.get(“/”)
def read_root():
return {“Hello”: “World”}

There ya go! You just made an app that says “Hello World.” How cute is that?

Step 4: Run Locally (Like Testing Before Eating)

Before we put our precious creation on the internet—and risk it getting rejected like bad art—let’s try running it locally first! Go back to your terminal and type this:

uvicorn main:app –reload

If everything goes well, open a browser and go to http://127.0.0.1:8000/. If you see “Hello World,” do a little dance—because you did it!! 🎉

Step 5: Prepare Your Files for Hosting

Alrighty, it’s time to show off your masterpiece! But first, we need to get some things ready.

Create another file called requirements.txt and list down these magical words:

fastapi
uvicorn

This tells the hosting service what special ingredients they need for making your app work. It’s kinda like telling someone how to make cookies without giving them the cookies!

Step 6: Deploying Like a Boss

Okay now comes the fun part—deploying it online! Depending on which service you picked earlier (Heroku or Railway), you’ll have some steps here.

For Heroku:
– Install Heroku CLI because why not.
– Log in using heroku login command.
– Create an app using heroku create.
– Push your codes using git push heroku master.

For Railway:
– Just connect GitHub repo (that has your code) to Railway.
– Click ‘Deploy’ like you’re pushing the big red button in action movies.

And trust me – if all goes well, you’ll be showing off your app faster than anyone can say “FastAPI pizza!”

Step 7: Test Online Like It’s Game Day

Now head over to the URL given by whichever service you’ve used and pray to the coding gods that everything works!

Open it in the browser like you’re unwrapping birthday presents, and if it says “Hello World”—congratulations!!! You’re officially an internet chef cooking up tasty APIs!
