# Deploy and Host Grafana Alloy on Railway

Grafana Alloy is a lightweight telemetry collector that scrapes Prometheus metrics from your Railway services and forwards them to Grafana Cloud. Ship your metrics to Grafana Cloud without exposing your services to the public internet.

## About Hosting Grafana Alloy

Grafana Alloy runs as a sidecar service inside your Railway project's private network. It scrapes your application's `/metrics` endpoint using Railway's internal DNS (`service-name.railway.internal`) and forwards the data to Grafana Cloud via remote write. Since everything happens over Railway's private network, your metrics endpoint never needs to be publicly exposed. All you need is a Grafana Cloud account and your API credentials to get started.

## Common Use Cases

- Forwarding Prometheus metrics from a Go, Node, or Python backend to Grafana Cloud
- Monitoring LLM token usage, request latency, and error rates in real time
- Building observability dashboards without managing a self-hosted Prometheus instance

## Dependencies for Grafana Alloy Hosting

- A Railway project with at least one service exposing a `/metrics` endpoint
- A Grafana Cloud account (free tier works)
- A Grafana Cloud Access Policy token with metrics write permissions

### Deployment Dependencies

- [Grafana Cloud](https://grafana.com/products/cloud/)
- [Grafana Alloy Documentation](https://grafana.com/docs/alloy/latest/)
- [Prometheus client libraries](https://prometheus.io/docs/instrumenting/clientlibs/)

### Implementation Details

Set the following environment variables in Railway before deploying:
```
TARGET_URL=your-service-name.railway.internal:8080
GRAFANA_CLOUD_URL=https://prometheus-prod-xxxx.grafana.net/api/prom/push
GRAFANA_CLOUD_USERNAME=your_username
GRAFANA_CLOUD_API_KEY=your_access_policy_token
```

Get your `GRAFANA_CLOUD_URL`, `GRAFANA_CLOUD_USERNAME`, and `GRAFANA_CLOUD_API_KEY` from Grafana Cloud → Connections → Add new connection → Hosted Prometheus Metrics → Create a new token.

## Why Deploy Grafana Alloy on Railway?

Railway is a singular platform to deploy your infrastructure stack. Railway will host your infrastructure so you don't have to deal with configuration, while allowing you to vertically and horizontally scale it.

By deploying Grafana Alloy on Railway, you are one step closer to supporting a complete full-stack application with minimal burden. Host your servers, databases, AI agents, and more on Railway.
