About Vegeta
Vegeta is an HTTP load testing tool written in Go. It sends requests at a fixed rate you choose, rather than as fast as possible, which makes it easier to see how a service behaves at a known level of traffic.
Results can be encoded and passed to other subcommands for reports and plots. The same code is available as a Go library for building load tests into other programs, and the repository includes a Dockerfile and example scripts for ramping load.
Strengths
- Constant request rate for predictable load
- Composable subcommands for attack, report and plot
- Also usable as a Go library
Limitations
- Command line only
- No built-in scripting for complex user flows
