• Handles enterprise protocols such as SAP GUI and Citrix that open-source tools cannot.
• APM correlation makes root-cause analysis much faster than latency graphs alone.
• Both GUI design and as-code authoring, so mixed-skill teams can share a suite.

• Very high throughput per load generator thanks to the async architecture.
• Code-first scenarios that review, diff and refactor properly.
• The default HTML report is genuinely good enough to hand to a stakeholder.

• Expensive, with a procurement-scale sales process.
• Overkill for a straightforward web or API workload.
• Proprietary scripts do not port to other tools.

• Historically Scala-first; the Java and JavaScript DSLs are newer and less documented.
• Fewer protocols than JMeter.
• Distributed load without the enterprise product means building your own orchestration.

Large enterprises performance-testing SAP, Citrix or Oracle estates.

JVM teams wanting code-first performance tests with excellent reporting.
