Checkly and Grafana Cloud represent two distinct philosophies in monitoring and observability. Checkly is a specialist platform that excels at Playwright-based synthetic monitoring with native CI/CD integration and monitoring-as-code workflows. Grafana Cloud is a generalist observability platform that provides capable k6-based synthetic monitoring as one component of a unified metrics, logs, traces, and dashboarding ecosystem. The choice depends on whether your team needs focused synthetic monitoring with superior developer workflow integration, or comprehensive observability with cross-signal correlation capabilities.

Checkly and Grafana Cloud represent two distinct philosophies in monitoring and observability. Checkly is a specialist platform that excels at Playwright-based synthetic monitoring with native CI/CD integration and monitoring-as-code workflows. Grafana Cloud is a generalist observability platform that provides capable k6-based synthetic monitoring as one component of a unified metrics, logs, traces, and dashboarding ecosystem. The choice depends on whether your team needs focused synthetic monitoring with superior developer workflow integration, or comprehensive observability with cross-signal correlation capabilities.
Choose Checkly if:
Choose Checkly if your primary need is Playwright-based synthetic monitoring integrated into CI/CD pipelines. Best for development teams practicing continuous deployment who want to reuse existing Playwright test suites as production monitors, with predictable pricing starting at $24/month for the Starter plan.
Choose Grafana Cloud if:
Choose Grafana Cloud if synthetic monitoring is one part of a broader observability strategy spanning metrics, logs, and traces. Best for platform engineering teams managing microservices who need to correlate synthetic test failures with infrastructure metrics and application traces in a single unified platform.
This verdict is based on general use cases. Your specific requirements, existing tech stack, and team expertise should guide your final decision.
No. Checkly is specifically a synthetic monitoring platform and does not collect infrastructure metrics, application logs, or distributed traces. If your observability needs extend beyond synthetic monitoring to include metrics from Prometheus, logs from your application stack, or distributed trace analysis, you will need additional tools alongside Checkly. Grafana Cloud covers all of these signal types in one platform.
Grafana Cloud's synthetic monitoring uses k6 for scripting, not Playwright. The k6 browser module supports Chromium-based browser automation, but it uses k6's own JavaScript API rather than Playwright's API. Teams with existing Playwright test suites cannot directly reuse them in Grafana Cloud without rewriting them in k6 syntax. Checkly natively supports Playwright scripts.
Yes, and this is a common pattern. Teams use Checkly for Playwright-based synthetic monitoring integrated into their CI/CD pipeline, then export Checkly metrics to Grafana Cloud via the Prometheus-compatible metrics endpoint. This gives teams Checkly's superior CI/CD integration and Playwright support while leveraging Grafana Cloud's dashboarding and correlation capabilities for the broader observability picture.
With Checkly, the Team plan at $64/month covers 10 users with 75 monitors, 12K browser checks, and 100K API checks. Additional monitors cost $8 per 25. With Grafana Cloud, costs depend on usage: the free tier covers basic needs, but a team running 50 synthetic checks plus 30K metrics series plus 100 GB logs could range from $50 to $200+ per month depending on volume. Checkly is more predictable; Grafana Cloud can be cheaper or more expensive depending on your total telemetry footprint.
Both platforms offer high availability with distributed infrastructure. Checkly provides a public status page and has historically maintained strong uptime for its check execution infrastructure. Grafana Cloud, backed by Grafana Labs (valued at over $6 billion), operates across multiple cloud providers with enterprise SLAs available on higher tiers. For mission-critical monitoring, both platforms offer private check locations that reduce dependency on shared infrastructure.
