## FAQ
### Who is LoadFocus for?
LoadFocus 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: LoadFocus. Deployment model: cloud. Free plan with paid usage-based plans. Confirm details against the official site and a short proof-of-concept in your environment.

### How does LoadFocus differ from Grafana Cloud k6?
Compared with Grafana Cloud k6, scripting centers on JavaScript rather than JavaScript, TypeScript. LoadFocus lists protocols HTTP, HTTPS, WebSocket; Grafana Cloud k6 lists HTTP, HTTPS, WebSocket, gRPC. 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 LoadFocus use?
LoadFocus uses JavaScript 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. 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 LoadFocus?
LoadFocus 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 plan with paid usage-based plans. Confirm details against the official site and a short proof-of-concept in your environment.

### What are known limitations of LoadFocus?
LoadFocus 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.
