## Documentation

# Deploy and Host

`peek` gives your local server a public URL through your own hosted relay.

This template deploys the peek relay on Railway. After deploy, add your domain and wildcard domain, then use the peek CLI to expose a local app.

## About Hosting

Set `PEEK_DOMAIN` to your domain, without `https://`.

Example:

`example.link`

Add both domains to the Railway service:

`example.link`  
`*.example.link`

Then add the DNS records Railway gives you.

## Why Deploy

Deploying the relay gives you your own public tunnel server. Your local machine connects to it with the peek CLI, and public visitors use generated URLs like:

`https://{random}.example.link`

## Common Use Cases

- Share a local web app demo
- Test webhooks against localhost
- Create temporary preview URLs
- Expose personal apps through your own domain

## Dependencies for

The peek CLI runs on your local machine:

`peek localhost:3000 --domain  --token `
