Gatling vs LoadNinja - Emmanuel Katto

Gatling:

It's like a DIY toolkit you can use for free.
You'll need some knowledge about a programming language called Scala to use it effectively.
It's really good at handling a lot of work without needing too many computers.
You can customize your tests a lot to make them match what your real users do.
It's best if you're comfortable with programming and want a lot of control over your tests.

LoadNinja:

It's like renting a powerful tool that's easy to use.
You don't need to know much about programming; it's more like recording and playing back actions.
It uses real web browsers to do its testing, which makes it very similar to what real users experience.
It gives you detailed reports and helps you understand what's going on during testing.
It's great if you want something that's quick to set up, easy to use, and provides detailed feedback.
