Grafana Synthetic Monitoring vs Checkly
Feature checklists rarely decide anything. What decides it is the pricing metric, who has to write the tests, and which limitation you can live with.
Entry price
Free tier available
Free tierFrom $24 per month (Starter; Team is $64)
Free tierWhat drives the bill
The metric that actually scales your invoice.
Cheap if you already run Grafana Cloud; results are plain Prometheus metrics you already know how to use.
Priced by check runs; browser checks cost more than API checks, and frequency multiplies the bill. Team at $64 adds 75 monitors, 30-second frequency, all 22 locations and private locations.
Free tier
Included in the Grafana Cloud free tier with a monthly check allowance.
Hobby: 10 uptime monitors, 10k API and 1k browser check runs a month across 6 locations.

Strengths
- 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.
- One Playwright script serves as both an E2E test and a production monitor.
- Monitoring-as-code fits GitOps workflows and code review.
- Excellent developer experience and clear, published pricing.
Limitations
- 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.
- Playwright-centric; teams on other frameworks get less benefit.
- Browser checks at high frequency across many locations get expensive.
- Not a full observability platform — no APM or log management.
Best for
Teams already running Grafana Cloud and k6.
Engineering teams already using Playwright who want production journeys monitored.
All of these integrate with: PagerDuty, Slack, Terraform.
