Grafana Has a Free Observability Stack — Monitor Everything with Beautiful Dashboards

Grafana is the industry-standard open-source platform for monitoring and observability.

What You Get for Free

• Grafana — beautiful dashboards for any data source
• Prometheus — metrics collection and alerting
• Loki — log aggregation (like Elasticsearch but 10x cheaper)
• Tempo — distributed tracing
• Alloy — unified telemetry collector (replaced Grafana Agent)
• Alerting — Slack, PagerDuty, email, webhook notifications
• 200+ data source plugins — PostgreSQL, MySQL, InfluxDB, CloudWatch, and more
• Grafana Cloud free tier — 10K metrics, 50GB logs, 50GB traces

Quick Start

# Docker Compose — full LGTM stack
docker compose up -d grafana prometheus loki

# Or Grafana Cloud (free): grafana.com/auth/sign-up
# No infrastructure to manage, generous free tier

Why Teams Choose Grafana

DataDog costs $15-23/host/month. New Relic has complex pricing. Grafana:

• Free self-hosted — no per-host pricing
• Grafana Cloud free tier — enough for small-to-medium apps
• Unified platform — metrics, logs, traces in one place
• Community dashboards — 5,000+ pre-built dashboards

A 10-person startup was paying $2,100/mo for DataDog. They migrated to self-hosted Grafana + Prometheus + Loki on a $40/mo server — same dashboards, same alerts, 98% cost reduction.
