What do you like best about k6?

Using k6, I can have a performance test up and running in 5 minutes, complete with load model and thresholds. There has never been a performance test tool that could do that, and I've been using them all for the past twenty years. Since the tests are written in JS, I have unlimited flexibility and can create modules or import libraries when I need them. The resource usage of the running tool is negligible, and spinning up large performance tests from my local is a non-issue. The support is ridiculously good - I have never had an issue go unsolved, and usually it is within a day. Review collected by and hosted on G2.com.

What do you dislike about k6?

I am looking forward to seeing more functionality in the cloud product since I would like it to be able to automatically do deltas on each test step. I understand that this is already on the roadmap. Also, the cloud product is not currently passing the configured name of my test step to my APM (Datadog, in this case) which hampers my ability to visualize and store my cloud tests. Review collected by and hosted on G2.com.

What problems is k6 solving and how is that benefiting you?

Honestly, the biggest problem leading to our adoption of k6 was that we needed complex test flows (Okta authentication, in this case) spun up very quickly and by one person, and for no license cost. K6 delivered in a way that I had never achieved with Loadrunner, JMeter, Gatling, Locust, Artillery, or any of the other tools would have been able to. And I have used them all.

What problems is k6 solving and how is that benefiting you?

I have microservices that 1. render pdf documents, 2. convert pdf to excel documents, 3. download documents.

I was looking for a load tester who does load testing extensively; I started exploring available tools like JMeter, locust, postman, k6 etc.

I tried all other load testing software; Not one does complete load testing. I found k6 and were able to achieve maximum open connections Review collected by and hosted on G2.com.
