This guide walks you through the steps to deploy your Pytherin project using Reflex, so your landing page can go live in just a few minutes. Reflex Hosting offers a free plan so you can deploy one project for free.

1. Make sure you have a requirements.txt file

In your project, run

pip freeze > requirements.txt

This ensures all your Python dependencies are listed and ready for deployment.

2. Log in to Reflex Cloud

• You need a Reflex Cloud account to deploy, run

reflex cloud login

You’ll be redirected to your browser to sign in or signup with GitHub or Gmail.

3. Deploy your app

• Once you’re logged in click on the top-right button named “How to deploy”

• You will see your project number like this

  reflex deploy --project f88b1574-f101-####-####-5f##########
  

• Copy it, go to your project terminal and add --envfile .env at the end to pass your environment variables

  reflex deploy --project f88b1574-f101-####-####-5f########## --envfile .env
  

Reflex will guide you through a few prompts:

• It may ask if you want to update your requirements.txt if it detects differences.
• If your app hasn’t been deployed before, it’ll prompt you to confirm the creation of a new app.
