Grafana Cloud Synthetic
Grafana Cloud's synthetic monitor — free tier integrated with full observability suite.
Free tier: 10 probes, free forever
What it does well
- Integrates natively with the Grafana LGTM stack (Loki, Grafana, Mimir, Tempo).
- Generous free tier offers 10,000 series for metrics, 50GB for logs, and synthetic checks.
- Supports multi-step browser transaction tests using Playwright scripts for complex user flows.
Where it falls short
- Check frequency on the free tier is limited to a 1-minute minimum interval.
- Can be complex to configure for users not already familiar with the Grafana ecosystem.
- Fewer global probe locations compared to more established, specialized synthetic monitoring providers.
