Pipelines are written in an expression-based config language, it bundles dozens of OTel Collector components plus Prometheus, Loki and Pyroscope integrations, interacts with Kubernetes resources directly, shares pipelines as modules and distributes work across a cluster of Alloy instances. ★~3.6k.","theCatch":"The Alloy config syntax is its own language, so it is another thing to learn on top of OTel YAML. It is tuned for Grafana backends; for a pure OTel setup, the upstream Collector may be simpler. Migrating from Grafana Agent or Promtail takes conversion work.","verdict":"The obvious collector if you run Grafana's LGTM stack.","addedAt":"2026-10-18","featured":false,"domain":"Observability","subSpecialty":"Observability","subcategory":"Observability","tags":["self-host","permissive","observability","active"],"capabilities":[],"surfaces":["Self-host"],"ecosystem":["Multi-platform"],"licenseModel":"Apache-2.0","githubStars":3623,"starsPerWeek":26,"access":"free","archived":false,"repo":{"createdAt":"2024-02-28","pushedAt":"2026-10-19","license":"Apache-2.0","archived":false,"checkedAt":"2026-10-19"}},"related":[{"slug":"sentry","name":"Sentry","tagline":"Error tracking that actually helps"},{"slug":"grafana","name":"Grafana","tagline":"Dashboards for everything observable"},{"slug":"prometheus","name":"Prometheus","tagline":"Time-series metrics for cloud-native"},{"slug":"opentelemetry","name":"OpenTelemetry","tagline":"Vendor-neutral observability framework"},{"slug":"datadog","name":"Datadog","tagline":"Unified observability platform"}],"links":{"self":"/api/gems/grafana-alloy","html":"/gems/grafana-alloy","markdown":"/gems/grafana-alloy.md","category":"/api/gems?category=observability","categoryPage":"/stacks/observability"}}
