ghz VS Kreya

I once built a quick and dirty load testing tool for a public facing service we built. The tool was pretty simple - something like https://github.com/bojand/ghz but with traffic and data patterns closer to what we expected to see in the real world. We used argo-workflows to generate scale.

One thing which we noticed was that there was a considerable difference in performance characteristics based on how we parallelized the load testing tool (multiple threads, multiple processes, multiple kubernetes pods, pods forced to be distributed across nodes).

I think that when you run non-distrubuted load tests you benefit from bunch of cool things which happen with http2 and Linux (multiplexing, resource sharing etc) which might make applications seem much faster than they would be in the real world.

I'm not sure. Maybe you can write to the discussion section of the repo https://github.com/bojand/ghz/discussions

In part 1 we looked at ghz for load testing gRPC services, and now I want to cover k6, which claims to be a modern load testing tool built for developer happiness. After only a brief experience with it I can see why is that and why Grafana moved to acquire k6 earlier this year.

It should be unbound, in this particular benchmark we set ghz concurrency to 50 and connections to 5 and we don't set the rps flag of ghz (e.g. --rps=2000, from this tool)

a second container running ghz makes unary requests to the server

Looks very nice; I've also given up with Postman. gRPC support would probably get Bruno into my daily workflow immediately. I spent a couple hours in Postman trying to get gRPC to work and could not- the .proto files were never used successfully, and I had better experiences with Kreya [0] and grpcui [1].

Kreya [1] can do that. It is even optimized for it, so that diffs should be perfectly readable.

As one of the creators, I can recommmend https://kreya.app. It is not open source (like Postman), but has a strong focus on privacy and also stores the data locally.

As it has more powerful features (IMO) than most alternatives listed here, I am a little disappointed that it isn't mentioned more often.

There is also https://kreya.app, which has more features, but is closed-source

Given the recent update[0] pushed by the Insomnia team I am now looking for alternatives.

For now the best alternative I've found is Bruno[1]. But sadly it does not support gRPC.

Does anyone have a better solution?

These are some options I've looked into:

- https://hoppscotch.io/

- https://hurl.dev/

- https://recipeui.com/

- https://kreya.app/

- https://github.com/flawiddsouza/Restfox

[0] - https://github.com/Kong/insomnia/issues/6585

[1] - https://github.com/usebruno/bruno

If you need gRPC, I can recommend https://kreya.app/

I like Kreya (kreya.app), but I am biased, since I am one of the creators :)

Have you tried Kreya? While it does not support all of the many features of Postman, it has some innovative features. While also being web-based, it uses the native WebView of the OS, resulting in less RAM-usage than Electron based apps.
