NexusBridge Builder

Three steps to your own private SMS bridge.

1

Deploy Server

2

Enter URL

3

Build App

🚀 Deploy your server to Railway

Railway hosts your server.py for free so your Android phone can reach it anywhere on the internet. Click the button below to deploy in one click — no credit card needed.

Deploy to Railway

How to find your URL after deploying

1
Click Deploy to Railway above. Sign in with GitHub when prompted.
2
Railway will create a new project and start deploying. Wait for the build to finish (green tick ✓).
3
In your Railway project, click the service (the box with your app), then open the Settings tab.
4
Scroll to Networking → Public Networking and click Generate Domain if no domain is shown yet.
5
Copy the URL — it looks like https://yourapp-xxxx.up.railway.app — and come back here.

💡 Your Railway URL will look like:
https://sms-bridge-production-xxxx.up.railway.app

Already have a server URL? Skip straight to the next step.

Enter your Server URL

Paste the Railway (or other) URL where server.py is running. This will be baked into both the web app and the Android APK.
