# Deploy and Host XChan on Railway

XChan is a web app for pairing two devices and sending an ephemeral secret (for example a password from a computer you already have to a machine you are setting up). Each browser creates a non-exportable P-256 key pair. Pairing exchanges public keys through the server. Messages are ECIES-encrypted. The server is a relay only.

## About Hosting XChan

Hosting XChan is a single Node process. Pairing is one FIFO queue for everyone on that instance, so use one replica and do not run a public multi-tenant deployment. There is no database: identity keys and channels live in the browser, and the server does not store keys, channels, or messages. No environment variables are required. Railway should attach a public HTTP domain. The included Dockerfile builds with npm ci / npm run build and starts with npm start.

## Common Use Cases

- Send a password from an already-authenticated computer to a machine you are setting up
- Self-host a private pairing relay for two of your own devices
- Move a short secret between a laptop and a phone without email or chat

## Dependencies for XChan Hosting

- Node.js runtime (provided by the Dockerfile)
- No database, Redis, or object storage

### Deployment Dependencies

- [XChan source on GitHub](https://github.com/saldoukhov/xchan)
