vegeta command [options]

vegeta is an HTTP load testing tool that sends requests at a constant, configurable rate. The attack command generates traffic and streams binary results to stdout, which can be piped to report for statistical analysis or plot for HTML visualization.
This pipeline design allows flexible composition of load test workflows. Target definitions support multiple endpoints, HTTP methods, headers, and request bodies. Reports include latency percentiles, success rates, and throughput metrics, making it straightforward to identify performance regressions and capacity limits.

High rates need tuning. System limits may apply. Target server must handle load.

Vegeta was created by Tomás Senart for HTTP load testing. Named after the Dragon Ball character, it emphasizes power and speed.
