Note: Streamlit Community Cloud does not support custom domain mapping (e.g.,
openprompt.uk). See Option 2 or 3 below for custom domain hosting.
Deploy the Streamlit app on a VPS (e.g., AWS EC2, DigitalOcean, Hetzner) and use Nginx as a reverse proxy:
server {
listen 80;
server_name openprompt.uk www.openprompt.uk;
location / {
proxy_pass http://localhost:8501;
proxy_http_version 1.1;
proxy_set_header Upgrade $http_upgrade;
proxy_set_header Connection "upgrade";
proxy_set_header Host $host;
proxy_set_header X-Real-IP $remote_addr;
proxy_set_header X-Forwarded-For $proxy_add_x_forwarded_for;
proxy_set_header X-Forwarded-Proto $scheme;
proxy_read_timeout 86400;
}
}Then point your domain's DNS A record to your server IP and add SSL via Let's Encrypt:
sudo apt install certbot python3-certbot-nginx
sudo certbot --nginx -d openprompt.uk -d www.openprompt.ukIf you want to keep using Streamlit Community Cloud but serve it from openprompt.uk:
- Deploy to Streamlit Cloud (get
https://your-app.streamlit.app) - Host a simple HTML page on
