hey! so for hosting python backend on railwa, here's what actually works:main thing is use a production server like gunicorn (for flask/django) or uvicorn (for fastapi). don't use the dev server in production.to set it up add gunicorn to your requirements.txt, then set your start command directly in railway's service settings. something like:gunicorn app:appor for fastapi:uvicorn main:app --host 0.0.0.0 --port $PORTyou can also use a Procfile but railway recommends just setting it in the dashboard nowimportant stuff:always use the $PORT environment variable that railway provideskeep requirements.txt up to dateturn debug off for productionuse railway's environment variables for any secrets/api keysif you need a database, add postgres from railway's database servicewhat you need:requirements.txt (or pyproject.toml)your main python filesthat's basically itrailway auto-detects everything for you. just connect your github repo, railway figures out it's python, and deploys it. way simpler than it used to be.then just generate a domain in the networking settings and you're live.hope this help you
