Feature checklists rarely decide anything. What decides it is the pricing metric, who has to write the tests, and which limitation you can live with.

Strengths
- Zero configuration; useful output in seconds.
- Good percentile reporting for such a small tool.
- Scriptable from Node for micro-benchmarks in CI.
- The broadest protocol coverage available anywhere.
- Extremely mature analysis and correlation tooling.
- Accepted by enterprise architecture and audit functions without argument.
Limitations
- Single endpoint only — no user journeys, no correlation, no think time.
- No distributed execution.
- HTTP/1.1 focused.
- Very expensive, and the protocol-bundle licensing model is hard to predict.
- Dated tooling and a steep learning curve; specialists are a distinct job role.
- Poor fit for continuous, developer-run performance testing.
Best for
Quick endpoint benchmarks and micro-optimisation work.
Large enterprises with legacy protocol requirements and an existing performance-engineering team.
