The attractive UI and simple UX make the tool easy to use if you're unfamiliar with it—this tool considered from the cheap tools can be handled from the companies budgets. The automation features are extra. Review collected by and hosted on G2.com.

Missing important feature " Cross Browser Testing," if they added this feature, it would be excellent. Review collected by and hosted on G2.com.

There are a lot of things that I like in this product like, it really has very good documentation and every good GUI that makes the use of this product so easy. Review collected by and hosted on G2.com.

- Ease of use

- Reduced bulkiness (as compared to Jmeter)

- Easy to read UI Review collected by and hosted on G2.com.

- Free tier allows just 50 users at a time (most load tests would require more than that number) Review collected by and hosted on G2.com.

We can use this tool for both functional as well load testing. this is the best feature as per my overall usage. It's builtin with CI so we can use for Devops as well. Review collected by and hosted on G2.com.

As compare to JMeter, it does not support many built-in protocols like TDP, SMTP. It provides significantly less functionality in its free version. Review collected by and hosted on G2.com.

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.

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.

There is a lot to like about k6. It provides flexible functionality with reliability that we require daily, add to that excellent customer support, and you got yourself a pretty good tool for a low cost. Review collected by and hosted on G2.com.

On the earlier versions of the platform, we had some issues with load generators failing to start failing the test, but that looks like a thing of the past now as I haven't seen this happening in a while. Review collected by and hosted on G2.com.

I like the speed in the definition of the scripts and the low consumption of resources compared to JMeter. Review collected by and hosted on G2.com.
