Yeah — you definitely can deploy a Python Gradio app on Railway. You just treat it like any other Python web service, make sure it listens on the right host/port, and let Railway handle the hosting side. It’s pretty popular for hosting ML demos, AI tools, and just random Gradio projects. (Medium)

Here are some solid reference URLs you can use to get going:

🧠 Key Tips for Deploying Gradio on Railway

To actually make it work, here are the essentials most guides will tell you:

1. Set the server host & port Gradio apps default to localhost. For Railway you need to listen on all interfaces and use its assigned port:

import os  
demo.launch(server_name="0.0.0.0", server_port=int(os.environ.get("PORT", 7860)))  

1. Create requirements.txt Make sure it lists gradio and any other libs you use:

gradio  

1. Add a Procfile This tells Railway how to start the app:

web: python app.py  

1. Push to GitHub + deploy Link your repo in Railway, and choose Deploy from GitHub.
2. Realtime logs & debug Railway’s dashboard lets you see deployment logs — very useful for port/host errors. (Medium)

Thank you Medapro. I eventually got there by giving the Claude Code the medium article. My app structure isn't as flat and simple as the article, but I got there in the end. Thank you.
