Gatling vs Locust: What are the differences?

Developers describe Gatling as "open-source load testing framework based on Scala, Akka and Netty". Gatling is a highly capable load testing tool. It is designed for ease of use, maintainability and high performance Out of the box, Gatling comes with excellent support of the HTTP protocol that makes it a tool of choice for load testing any HTTP server. As the core engine is actually protocol agnostic, it is perfectly possible to implement support for other protocols. For example, Gatling currently also ships JMS support.. On the other hand, Locust is detailed as "Define user behaviour with Python code, and swarm your system with millions of simultaneous users". Locust is an easy-to-use, distributed, user load testing tool. Intended for load testing web sites (or other systems) and figuring out how many concurrent users a system can handle.

Gatling and Locust belong to "Load and Performance Testing" category of the tech stack.

Gatling and Locust are both open source tools. Locust with 10.3K GitHub stars and 1.48K forks on GitHub appears to be more popular than Gatling with 4.28K GitHub stars and 912 GitHub forks.
