Railway is a popular choice for Python developers who want to get a Django app live without managing servers. It works well for side projects and experiments. But before you start, there are setup steps and production limits that most guides gloss over.

This guide walks you through the complete process: preparing your project, connecting PostgreSQL, setting environment variables, running migrations, and understanding where Railway starts to show its limits. If you have deployed Django on Heroku or Render before, you will find the flow similar but with a few Railway-specific differences worth knowing.

What You Need Before You Start

Before you open the Railway dashboard, make sure you have these ready:

• A working Django project: Your app should run locally without errors. Even a basic project is fine.
• A GitHub repository: Railway deploys directly from GitHub. Your code needs to be pushed to a repo before you connect it.
• A Railway account: Sign up at railway.com. The Trial plan gives you $5 in free credits to get started.
• Python 3.10 or higher: Railway supports Python 3.10, 3.11, and 3.12. Check your local version before you deploy.

That is everything. No CLI install required, no config files to create just yet. Railway detects most of what it needs from your project automatically.

Before you write a single config file, make sure your app runs locally. Deployment errors are much harder to debug than local ones. If it does not work on your machine, it will not work on Railway either. See how Railway’s hosting works under the hood if you want the full picture.

How to Prepare Your Django Project for Railway

Railway needs four things from your project before it can deploy it successfully.

A Procfile: This tells Railway how to start your Django app. Create a file named Procfile (no extension) in the root of your project with this single line:

web: gunicorn yourprojectname.wsgi

Replace yourprojectname with the name of the folder that contains your settings.py file.

A requirements file: Railway reads requirements.txt to install your dependencies. If you do not have one, run pip freeze > requirements.txt in your project directory. Make sure it includes gunicorn (the server that runs Django in production), psycopg2-binary (the PostgreSQL connector), dj-database-url (reads your database connection from an environment variable), and whitenoise (serves your static files without a separate CDN).

A runtime file: Create a file named runtime.txt in your project root and add one line: python-3.11.x. This tells Railway which Python version to use.

Production settings: In your settings.py, set DEBUG = False for production and make sure ALLOWED_HOSTS includes your Railway domain. You will add the actual domain after your first deploy. Also add whitenoise to your MIDDLEWARE list, just below Django’s SecurityMiddleware, so static files are served correctly.

These four files are all Railway needs to build and run your Django app.

The most common reason a Railway Django deploy fails is a missing or misconfigured Procfile. Double-check the project name in your web: gunicorn command before you push. The name must match your wsgi.py folder exactly. Learn how other platforms handle this differently in this guide to deploying Django on Netlify.

How to Deploy Django on Railway

With your project files ready and pushed to GitHub, here is the full deployment process.

Step 1: Create a New Railway Project and Connect Your Repo

Log into your Railway dashboard and click New Project. Select Deploy from GitHub repo and authorise Railway to access your repositories. Choose the repo that contains your Django app. Railway will detect that it is a Python project and start a build automatically.

Wait for the first build to complete. It will likely fail at this point because your database and environment variables are not set up yet. That is expected.

Step 2: How to Set Up Environment Variables on Railway

In your Railway project, click on your Django service and go to the Variables tab. Add the following:

• SECRET_KEY: A long random string. Use a Django secret key generator to create one.
• DEBUG: Set this to False for production.
• ALLOWED_HOSTS: Add your Railway-generated domain here. You will find it under the Settings tab once Railway assigns one.
• DATABASE_URL: You do not need to set this manually. Railway auto-injects it when you add a PostgreSQL service to your project (covered in the next step).

Railway makes environment variables available to your app at runtime. Your Django settings can read them directly using os.environ.get().

Step 3: How to Connect PostgreSQL to Your Django App on Railway

Inside your Railway project, click New Service and select Database, then choose PostgreSQL. Railway spins up a Postgres instance and immediately generates a DATABASE_URL variable that is shared across your project services.

Your Django app reads this variable automatically if you have configured dj-database-url in settings.py. The connection is internal to your Railway project, so no additional networking setup is needed.

Once PostgreSQL is added, go back to your Django service and trigger a redeploy. After it builds successfully, open the Shell tab in your service and run:

python manage.py migrate

This applies all your database migrations to the new Postgres instance. You only need to do this manually the first time, and after any deployment that adds new migrations.

Railway auto-injects DATABASE_URL the moment you add a Postgres service. You do not need to copy or paste any connection strings. If your migrations are failing, the most likely cause is that dj-database-url is not installed or not configured in settings.py. See how this compares to deploying a Python app on Heroku where the setup is nearly identical.

Common Errors When Deploying Django on Railway

Most deployment failures on Railway fall into a small number of patterns.

App builds but crashes immediately on start: This almost always means your Procfile is wrong. Check that the project name in web: gunicorn yourprojectname.wsgi matches your actual project folder. If there is no wsgi.py in that folder, gunicorn cannot start.

Static files return 404 after deployment: Railway does not serve static files for you. You need whitenoise installed and added to your middleware. Also make sure you run python manage.py collectstatic before deploying, or add it to your build command in Railway settings.

Database migrations not applied: Railway does not run migrations automatically. After every deployment that includes model changes, open the Shell tab in your service and run python manage.py migrate manually.

DisallowedHost error in the browser: Your ALLOWED_HOSTS setting in settings.py does not include your Railway domain. Copy the domain from the Settings tab and add it to the list. Setting ALLOWED_HOSTS = ['*'] works as a temporary fix but should never be used in a real production environment.

Build fails with “no module named gunicorn”: Gunicorn is not in your requirements.txt. Run pip freeze > requirements.txt locally after installing it, commit the file, and push again.

Most Railway Django errors are config errors, not code errors. Check your Procfile, your requirements, and your environment variables before digging into your application code. These three files cause 90% of failed deployments. See how Railway compares to Heroku for Django teams to understand the full picture.

Where Railway Falls Short for Django in Production

Railway works well for prototypes and personal projects. For production Django apps that need to stay fast and reliable, there are a few limitations worth knowing before you commit.

Apps sleep on the Hobby plan. When your service receives no traffic for a period of time, Railway puts it to sleep. The next visitor triggers a cold start, which can add several seconds to the first response. For side projects this is fine. For production APIs it is a real problem.

No auto-scaling. Railway does not automatically scale your service based on traffic. If your Django app gets a traffic spike, you need to manually adjust resources in the dashboard. By the time you notice, users are already seeing slow responses or errors.

Celery workers need a separate paid service. Running background tasks with Celery requires deploying a second service in your Railway project, with its own resource allocation and its own billing. This makes Railway significantly more expensive for apps that rely on async task processing.

Costs add up quickly with multiple services. A production Django setup on Railway typically needs a web service, a PostgreSQL service, and a Redis service for Celery. Each service adds to your monthly bill. What starts as a $5/month platform can grow faster than expected.

These are not dealbreakers for every use case, but they are worth understanding before you plan a production deployment. For a broader look at the platform’s trade-offs, the Railway alternatives guide covers what developers typically move to when Railway no longer fits.

Railway is a great starting point, but production Django apps with real users need a platform that does not sleep, scales on its own, and does not charge extra for every additional service. That gap is where most teams start looking for alternatives.

Deploy Your Django Project With Agentic AI Now

If the Railway setup feels like more work than it should be, Kuberns is worth a look. It is an agentic AI deployment platform built for developers who want to go from code to production without a checklist.

Here is what the Django deploy flow looks like on Kuberns:

1. Connect your GitHub repo. Kuberns detects that it is a Django project automatically. No Procfile required.
2. Set your environment variables. Add SECRET_KEY, DEBUG, and any other variables in the dashboard. PostgreSQL is provisioned alongside your app in the same flow, no separate service setup needed.
3. Click deploy. Kuberns builds your app, runs migrations, and gives you a live URL.

The difference in practice: Railway takes 7 or more steps and requires manual shell commands for migrations. Kuberns handles it in 3 steps with no manual intervention after the first deploy.

Beyond setup, Kuberns does not sleep your service, includes auto-scaling without manual configuration, and supports Celery workers natively without requiring a separate paid service. For teams who want one-click Django deployment with AI, it removes the operational overhead entirely.

Kuberns handles what Railway makes you configure manually. If you are spending more time on deployment setup than on your application, that is a signal worth paying attention to.

Railway vs Kuberns for Django Deployment

Feature	Railway	Kuberns
Auto-detects Django project	Yes	Yes
PostgreSQL setup	Add-on, separate service	Built into deploy flow
App sleeps on inactivity	Yes (Hobby plan)	No
Zero-downtime deploys	Not on free tier	Yes
Celery worker support	Separate paid service	Native support
Auto-scaling	Manual	Automatic
Migration handling	Manual via shell	Handled automatically
Steps to first deploy	7 or more	3

The comparison is not just about features. It is about how much time you spend on deployment instead of your product. Railway gives you flexibility at the cost of setup time. Kuberns trades that flexibility for speed. For most Django developers building for real users, the trade is worth it.

Conclusion

Deploying Django on Railway is straightforward once you know the setup steps. Get your Procfile right, configure your environment variables, add PostgreSQL as a service, and run migrations after your first deploy. For side projects and experiments, Railway does the job.

For production apps that need to stay live, scale with traffic, and run background workers without extra cost, the limitations start to show. That is when it makes sense to look at a platform built for production from the start.

Kuberns handles the full Django deploy flow in three steps, with PostgreSQL, auto-scaling, and Celery support included. If you want to skip the manual setup and get your Django app live faster, it is the most direct path from your GitHub repo to a production URL.

Connect your repo and deploy your Django app on Kuberns today.

Frequently Asked Questions

Can I deploy Django on Railway for free?

Railway offers a Trial plan with $5 in free credits, but it is one-time only. Once those credits are used, you need to upgrade to the Hobby plan at $5 per month to keep your Django app running. The free trial is enough to test a deployment but not to run a production app long term.

Does Railway support Django with PostgreSQL?

Yes. Railway lets you add a PostgreSQL database as a separate service inside your project. Once added, Railway auto-generates a DATABASE_URL environment variable that your Django app can read using the dj-database-url package. You still need to run migrations manually after each deployment.

How do I run migrations on Railway?

After your Django app is deployed, open the Railway dashboard, go to your service, and open the Shell tab. Run python manage.py migrate from there. Railway does not run migrations automatically, so you need to do this after every deployment that includes database changes.

Why does my Django app keep sleeping on Railway?

On Railway’s Hobby plan, services that receive no traffic for a period of time are put to sleep to save resources. When a new request arrives, the app cold starts, which can cause noticeable delays. To avoid this on production apps, you either need to keep traffic flowing or switch to a platform that does not sleep idle services.

Does Railway support Celery and background workers for Django?

Railway supports Celery workers, but you need to deploy them as a separate service inside your project. This means a separate Railway service with its own resource allocation and billing. Background workers do not share the same service as your Django web process on Railway.

What is a good Railway alternative for Django deployment?

Kuberns is a strong alternative for deploying Django on Railway. It auto-detects your Django project, provisions PostgreSQL alongside your app in the same flow, and does not sleep idle services. Kuberns also supports Celery workers natively and includes auto-scaling without manual configuration.
