Grafana Alloy

What Grafana Alloy is

Grafana Alloy is a free, open-source collector for observability data. It uses a self-hosted deployment model and runs on Linux, macOS and Windows. Alloy supports logs, metrics and traces, allowing these telemetry types to be collected through one tool. Transform rules can modify incoming data, while data enrichment adds context before delivery. Multi-destination routing sends collected telemetry to more than one destination. Because it is self-hosted, operators decide where the collector runs and manage that infrastructure themselves. The open-source pricing model means no paid plan is listed. Its feature set centers on receiving observability data, changing or enriching it, and routing it onward. Teams choosing Alloy should consider both the supported telemetry types and the operational responsibility that comes with running a self-hosted collector.

Who it suits

Grafana Alloy suits teams that need to collect logs, metrics and traces in self-hosted environments. It is also relevant when telemetry must be transformed, enriched or routed to multiple destinations.

Getting started

1. Choose Linux, macOS, or Windows
2. Deploy Alloy in your self-hosted environment
3. Configure collection for logs, metrics, or traces
4. Apply transform rules or data enrichment
5. Set multi-destination routing

Verdict

Grafana Alloy brings telemetry collection, transformation, enrichment and routing into a free open-source tool. Its self-hosted model gives operators control over deployment but leaves infrastructure management to them.
