Grafana Has a Free Observability Platform — Dashboards for Any Data Source

Grafana is the open-source visualization platform — connect any data source, build any dashboard, alert on anything.

What You Get for Free

  • Any data source — Prometheus, InfluxDB, Elasticsearch, PostgreSQL, MySQL, CloudWatch, and 100+ more
  • Beautiful dashboards — drag-and-drop panel editor
  • Alerting — multi-channel alerts (Slack, PagerDuty, email, webhook)
  • Explore — ad-hoc query interface for debugging
  • Annotations — mark events on graphs (deploys, incidents)
  • Variables — template dashboards with dropdowns
  • Plugins — 1,000+ community plugins
  • Grafana Cloud — free tier with 10K metrics, 50GB logs, 50GB traces

Quick Start

docker run -d -p 3000:3000 grafana/grafana
# Open http://localhost:3000 (admin/admin)
Enter fullscreen mode Exit fullscreen mode
  1. Add data source (Prometheus, PostgreSQL, etc.)
  2. Create dashboard → Add panel → Write query
  3. Set up alerts → Choose notification channel

Why Developers Switch from Datadog

Datadog charges per host, per metric, per log GB:

  • Free — self-host with unlimited metrics and dashboards
  • Any data — not locked into one vendor's agent/format
  • Community — 1,000+ plugins, community dashboards
  • Grafana Cloud free tier — if you don't want to self-host

A startup's Datadog bill was $1,200/month for 10 hosts. After self-hosted Grafana + Prometheus: $0/month (runs on existing servers), same dashboards, same alerts.
