UptimeRobot vs Grafana Synthetic Monitoring

From $7 per month (indicative, Solo)

Free tier available

One of the best free tiers in infrastructure tooling; paid plans are still inexpensive.

Cheap if you already run Grafana Cloud; results are plain Prometheus metrics you already know how to use.

50 monitors at 5-minute intervals, free forever.

Included in the Grafana Cloud free tier with a monthly check allowance.

• Free tier covers what most small projects actually need.
• Five-minute setup with no configuration to learn.
• Status pages included even on lower tiers.

• Results are Prometheus metrics, so alerting and dashboards use tools you already have.
• Same k6 scripts serve load testing and synthetic monitoring.
• Good free tier within Grafana Cloud.

• No browser-based transaction monitoring — availability only.
• Basic alerting logic; expect some noise from transient failures.
• Limited reporting and no observability integration.

• Assumes you are in the Grafana ecosystem; standalone it makes little sense.
• Browser checks are less mature than Datadog's or Checkly's.
• Fewer probe locations than the dedicated vendors.

Side projects, small businesses and anyone who currently has no monitoring at all.
