Gatling vs Locust: What are the differences?

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.

Review ofLocustLocust

This is the best open source tool i have ever come across which does load testing at its best.

Python config code is really simple to write and good part is its extendable and there are many hooks available ... what else you need ..

Lastly, the web UI to monitor your swarming activity is too good and very helpful for identify bottlenecks and spikes real-time.
