JMeter vs Gatling
Answer JMeter offers GUI and multi-protocol flexibility on the JVM. Gatling is a code-driven, high-throughput engine with expressive scenarios (Scala/Java/JS depending on edition). Choose JMeter for recorder workflows and plugins; Gatling for engineer-owned, high-concurrency HTTP suites.
Curator verdict
Gatling shines when performance engineers write maintainable, code-reviewed load tests and need asynchronous high concurrency. JMeter still covers more protocol ground and has a larger generalist community. Gatling Enterprise adds ops features if you outgrow the open-source engine.

How to choose
- Choose Gatling for code-first HTTP performance with strong reporting DNA.
- Choose JMeter when GUI, plugins, or non-HTTP protocols matter more.
- Evaluate team language comfort: Java/Groovy vs Scala/Java/JS Gatling styles.
- Budget for Gatling Enterprise if you need distributed ops without building it.
- Both are self-hosted open cores with commercial cloud siblings available.
