## What it is
Grafana Cloud k6 provides managed execution and results for k6 test scripts. It connects load testing data with Grafana dashboards, alerts, and other observability signals.

## Choose it when
- 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

## Look elsewhere when
- Strictly air-gapped environments with no approved cloud path

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

## 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.

## FAQ
### 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.
