OpenText LoadRunner vs Vegeta
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
- The broadest protocol coverage available anywhere.
- Extremely mature analysis and correlation tooling.
- Accepted by enterprise architecture and audit functions without argument.
- Constant-rate model avoids the coordinated-omission problem that distorts VU-based tools.
- Single static binary, trivial to run anywhere.
- Composable output for scripting and pipelines.
Limitations
- 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.
- No scenarios or session state — one target list, one rate.
- No GUI or built-in reporting beyond plots.
- Go library usage required for anything sophisticated.
Best for
Large enterprises with legacy protocol requirements and an existing performance-engineering team.
Backend engineers who want rigorous constant-rate measurements of an endpoint.
