I have not used it myself but colleagues of mine recommend k6: https://k6.io/open-source/

There is also a Github repository keeping track of all the load-testing tools out there: https://github.com/denji/awesome-http-benchmark You will probably find something that will fit your bill.

I do not understand though why it is of any relevance what language the application is written in. Yes, Go and Rust indicate a certain speed and novelty but you can write fast applications with good UX in other programming languages too (and bad ones in Go and Rust).

That k6 app looks sleek, I'll try it out. Thanks!

Yes I don't mean to dismiss all other languages I just happen to only have these two runtimes and few others and I'm currently having problems with Java runtime which result in me not being able to run JMeter. Plus, if it's open source it can benefit me because these are the two languages I practically use.

Unlike Java applications, apps written in Go and Rust do not need a runtime installed on your computer. The same is true for C, C++ and a lot of other languages. You are most probably less constrained than you think.

You're right, thanks for explaining

+1 for K6. The open source is quite easy to setup and their cloud (freemium) makes life pretty easy to scale/distribute/visualize tests. I use it for https://wphostingbenchmarks.com for many years now (used to be Load Impact).

Yeah, k6 is great, super easy to use for programmers.
