## FAQ
### Who is Speedscale for?
Speedscale is best for teams that want managed load generation without operating generators themselves. It is commercial software, typically licensed for larger or governed programs. Vendor: Speedscale. Deployment model: hybrid. Commercial subscription; contact vendor for pricing. Confirm details against the official site and a short proof-of-concept in your environment.

### How does Speedscale differ from Apica?
Compared with Apica, deployment is hybrid versus cloud for Apica; scripting centers on YAML, Go rather than JavaScript. Speedscale lists protocols HTTP, HTTPS, gRPC; Apica lists HTTP, HTTPS, REST. 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 Speedscale use?
Speedscale uses YAML, Go for scripting or scenario definition. Runtime model: code-first scenarios where virtual users execute scripted behavior under load. OS support: Linux. Protocols: HTTP, HTTPS, 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 Speedscale?
Speedscale supports a hybrid path that can combine self-hosted controllers or agents with cloud or distributed load as the product allows. Teams often keep sensitive assets private while bursting generators into the cloud. Pricing model: Commercial subscription; contact vendor for pricing.

### What are known limitations of Speedscale?
