Vegeta is a versatile HTTP load testing tool and Go library that drills HTTP services with a constant request rate. It is usable both as a UNIX-composable CLI and as an embeddable Go package, with extensive reporting and distributed load testing support.

Use cases

load test an HTTP API at a constant request rate
benchmark endpoint latency and throughput
run distributed load tests against a web service
embed an HTTP attack generator in a Go program
generate latency histograms and reports from load tests

When to choose

you need constant-rate HTTP load generation that avoids coordinated omission
you want a single static binary that is easy to install and script
you need both a CLI and a Go library for load testing
you want rich reporting (text, histogram, JSON) from test results

When to avoid

you need protocol support beyond HTTP/1.1 and HTTP/2 (e.g. gRPC, WebSockets)
you need scenario-based or user-journey load testing with complex scripting
you need a GUI or record/replay proxy workflow
