## FAQ
### Who is Taurus for?
Taurus is best for engineers designing load, stress, and performance tests for web and service systems. It is open source, so teams can self-host and extend it. Vendor: BlazeMeter. Deployment model: self-hosted. Free; Apache License 2.0. Confirm details against the official site and a short proof-of-concept in your environment.

### How does Taurus differ from Apache JMeter?
Compared with Apache JMeter, scripting centers on Python, YAML rather than Java, Groovy. Taurus lists protocols HTTP, HTTPS, WebSocket; Apache JMeter lists HTTP, HTTPS, JDBC, JMS, FTP, TCP. 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 Taurus use?
Taurus uses Python, YAML for scripting or scenario definition. Runtime model: code-first scenarios where virtual users execute scripted behavior under load. OS support: Windows, macOS, Linux. 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 Taurus?
Taurus is primarily self-hosted; teams typically run generators on their own machines, CI runners, or private cloud. Plan for generator capacity, network access to targets, and result storage yourself. As open source, commercial support or hosted siblings may exist separately. Check the official site. Pricing note: Free; Apache License 2.0.

### What are known limitations of Taurus?
Taurus limitations to weigh: self-hosted tools require you to provision, scale, and observe load generators yourself. 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.
