The deta.sh cloud platform, is a free alternative to Heroku. This article is a step-by-step guide to deploying a Flask Python app for free.
Heroku is a good cloud platform to deploy and scale apps, but Heroku is no longer free. We can use Deta.sh cloud to freely deploy a Python app.
Create a free Deta account
Fire go to deta.sh and create an account using your email ID (Credit card not required )
Next, we need to select a region or auto.
Install deta CLI
Next, we need to install deta CLI, using this CLI we can deploy our Python web app. Run the following command to install it.
For Windows users run the below command in PowerShell.
iwr https://get.deta.dev/cli.ps1 -useb | iex
For Linux/Mac users run the below command.
curl -fsSL https://get.deta.dev/cli.sh | sh
After the installation, open the terminal and type deta command and ensure that the command is working. You will get similar output as below.
Create a Python web app
Let’s create a Python web app.
Type the following command in the terminal here cool_app is the name of our web app.
deta new --python cool_app
From the output, we can see the endpoint URL https://1wu115.deta.dev (This is our web app’s URL).
Open the app URL in the browser. Tada !!! our app is running. To see the code of our app navigate to cool_app folder. We can see main.py file.
Update app as a Flask app and deploy changes
Enter the directory cool_app and then create a file, requirements.txt, which tells Python dependencies to install.
Next, open the main.py in your favorite code editor and remove its content and paste the below code.
from flask import Flask app = Flask(__name__) @app.route('/', methods=["GET"]) def greet(): return "Hello from NoloWiz"
Code is simple it will greet the user with a message. Let’s deploy it.
To deploy these changes, simply run the command.
After the deployment let’s open our app URL in the browser.
There you have it, a simple free way to deploy and experiment with your Python web apps. Happy coding.
