# wrk alternatives

> wrk is an open source, self-hosted micro-benchmark CLI from wg / community, scripted in C, Lua. Teams look for wrk alternatives when the operating burden, the authoring language, or protocol coverage stops fitting. The closest recorded substitutes are Vegeta, hey, ApacheBench (ab), Autocannon, plus 8 more below — ranked here on license, deployment, scripting and protocols rather than on popularity.

- Canonical: https://perf.jmeter.ai/alternatives/wrk/
- Baseline: [wrk](https://perf.jmeter.ai/tools/wrk/)

## Stay with wrk when
- Quick HTTP or protocol micro-benchmarks from a single machine.
- Teams that prefer open-source licensing and self-hosting options.
- Groups comfortable scripting in C, Lua.

## Switch when
- Full multi-protocol enterprise journeys and rich business-flow reporting.
- Teams unwilling to operate generators, results storage, and scaling.
- Your protocol list runs past wrk: Apache JMeter also records JDBC, JMS, FTP.
- The team would rather author in Go: that is Vegeta.
