# Apache JMeter vs The Grinder

> Apache JMeter is an open source, self-hosted load testing tool from Apache Software Foundation, scripted in Java, Groovy. The Grinder is an open source, self-hosted load testing tool from The Grinder project, scripted in Jython, Java. It is discontinued. The practical split is the authoring language: Java, Groovy for Apache JMeter, Jython, Java for The Grinder.

- Compared: [Apache JMeter](https://perf.jmeter.ai/tools/apache-jmeter/) · [The Grinder](https://perf.jmeter.ai/tools/the-grinder/)

## Verdict
Both cover HTTP, HTTPS, and both sit in the load testing tool bracket. On recorded coverage Apache JMeter is the wider of the two (6 protocols against 2), which matters only if your workload actually uses the extra ones. The Grinder is discontinued with nGrinder named as its successor, so Apache JMeter is the safer default for new work. Team language and existing tooling usually settle Apache JMeter against The Grinder. Run the same scenario on both before you standardize; the rows below only tell you what is true on paper.
