Alternative to Gatling

Question

I’ve been having issues lately because my dependencies has been updated to use netty 4.1 and Gatling has not been updated for a while, and still work only on Netty 4.0.

Anybody knows any alternative to Gatling to create similar Simulations and scenarios for the performance test to be run automatically in my Maven life cycle?

Answer 1

If you look for something code-based it would be:

• Locust
• Grinder

For UI and/or XML based scenario definition you can check out:

• Tsung (this one can be reliably run on Linux/Unix only)
• Apache JMeter

Check out Open Source Load Testing Tools: Which One Should You Use? to learn more about the aforementioned tools and decide which one fits to your most.

Answer 2

As a nice replacement for Gatling I would recommend you to check the Locust. The good thing about the Locust specifically for you is that it is code based performance testing tool which does not enforce you to write the tests only in a specific programming language like Python. Because if you used Scala before, you might be more comfortable to switch to something like Java or even Kotlin while writing your tests which is more than doable using Locust framework.
