# ghz alternatives

> ghz is an open source, self-hosted protocol and API load tool from Bojan Djurkovic, scripted in Go, JavaScript. Teams look for ghz alternatives when the operating burden, the authoring language, or protocol coverage stops fitting. The closest recorded substitutes are Artillery, Tsung, Fortio, Drill, plus 5 more below — ranked here on license, deployment, scripting and protocols rather than on popularity.

- Baseline: [ghz](https://perf.jmeter.ai/tools/ghz/)

## Stay with ghz when
- API and protocol throughput or latency campaigns.
- Teams that prefer open-source licensing and self-hosting options.
- Groups comfortable scripting in Go, JavaScript.

## Switch when
- Teams unwilling to operate generators, results storage, and scaling.
- You need a vendor contract and support path: Gatling Enterprise is sold commercially.
- You would rather not run generators at all: Grafana Cloud k6 is vendor-hosted.
- Your protocol list runs past ghz: Artillery also records HTTP, HTTPS, WebSocket.
- The team would rather author in Erlang, XML: that is Tsung.
