• Zero configuration; useful output in seconds.
• Good percentile reporting for such a small tool.
• Scriptable from Node for micro-benchmarks in CI.

• 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.

• Single endpoint only — no user journeys, no correlation, no think time.
• No distributed execution.
• HTTP/1.1 focused.

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

Quick endpoint benchmarks and micro-optimisation work.

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