Answer

Grafana Cloud k6 is a fully-managed performance testing platform integrated into Grafana Cloud, powered by k6 OSS. It allows teams to create, run, and analyze load tests to detect performance issues and regressions, providing a unified view of performance testing results alongside other observability data like metrics, logs, traces, and profiles within the Grafana stack.

About

Grafana Cloud k6 is a fully-managed performance testing platform integrated into Grafana Cloud, powered by k6 OSS. It allows teams to create, run, and analyze load tests to detect performance issues and regressions, providing a unified view of performance testing results alongside other observability data like metrics, logs, traces, and profiles within the Grafana stack.

Best for

  • Teams that want managed load generation without operating injectors
  • Teams that want a free tier before committing to paid capacity
  • Groups comfortable scripting in JavaScript, TypeScript

Not the best fit when

  • Strictly air-gapped environments with no approved cloud path

Architecture and concurrency

Grafana Cloud k6 runs as a cloud service: scenarios use JavaScript, TypeScript, while generators and orchestration are vendor-managed.

Latest release

v2.2.0 · 2026-08-10

Release v2.2.0 features include: streaming of logs to Grafana Cloud during k6 cloud run --local-execution, the addition of chromium.connectOverCDP for browser test connections to running Chromium instances, availability of TextEncoder/TextDecoder as globals, WritableStream support in k6/experimental/streams, a new k6 cloud load-zone list command, and two new experimental feature flags: merge-run-tags and freeze-env.

Pricing

Grafana Cloud k6 utilizes a Virtual User Hour (VUH) billing model (specifically Fractional VUH v2). The platform offers a free tier (limited to 500 VUH/month) and self-serve pay-as-you-go options starting at $0.150 per VUH, with enterprise custom plans available. An online calculator is provided for cost estimation.

Frequently asked

ANSWER-SHAPED
Who is Grafana Cloud k6 for?

Grafana Cloud k6 is best for teams that want managed load generation without operating generators themselves. It offers a freemium path, so teams can start small before buying capacity. Vendor: Grafana Labs. Deployment model: cloud. Free tier with usage-based paid plans.

How does Grafana Cloud k6 differ from Loader.io?

Compared with Loader.io, scripting centers on JavaScript, TypeScript rather than None. Grafana Cloud k6 lists protocols HTTP, HTTPS, WebSocket, gRPC; Loader.io lists HTTP, HTTPS. Status is active versus active. Use the Test Rig to compare full specs side by side before a proof-of-concept.

What scripting language and concurrency model does Grafana Cloud k6 use?

Grafana Cloud k6 uses JavaScript, TypeScript for scripting or scenario definition. Runtime model: code-first scenarios where virtual users execute scripted behavior under load. OS support: Browser. Protocols: HTTP, HTTPS, WebSocket, gRPC. Match these to how your team already authors tests and which systems you must drive under load.

What is the cloud or enterprise path for Grafana Cloud k6?

Grafana Cloud k6 is cloud-hosted: you run tests on vendor-managed infrastructure without operating load generators yourself. That usually speeds ramp-up for distributed load while shifting capacity planning and data residency to the vendor. Pricing model: Free tier with usage-based paid plans.

What are known limitations of Grafana Cloud k6?

Grafana Cloud k6 limitations to weigh: cloud services trade operational simplicity for vendor pricing, data residency, and network path differences versus your production topology. Status: active. Always validate against your target protocols and scale with a proof-of-concept. Confirm details against the official site and a short proof-of-concept in your environment.
