k6 Reviews & Product Details

I enjoy the great community behind it that strive to support a state of the art technical documentation and real time support for the end users. Not to mention the easy way to get started and build an efficient solution for your engineering teams that can be integrated in your development cycle with multiple extentions and observability techniques that will empower your technical analysis and reporting.

If i wanted to mention something (i am not finding much to tell...) i would say the programming language support as it only supports javascript/typescript. Teams familiar with other technologies may need a small learning curve. But it is super easy for anyone to get started amrk my words! Review collected by and hosted on G2.com.

The best thing regarding k6 is that the learning curve is not steep. You can create a serious load testing solution within hours. Besides simplicity, you can generate thousands of virtual users from a single machine. k6 supports hybrid load testing out of the box. Review collected by and hosted on G2.com.

You cannot reuse your existing UI testing scripts for hybrid scenarios but create new scripts. However, the feature is still in the experimental phase, and I'm sure the support from the team will come. Review collected by and hosted on G2.com.

k6 is a very light weight tool to help get started with performance, but at the same time have extensive tooling to scale towards complicated scenarios. Review collected by and hosted on G2.com.

k6's architecture doesn't allow you to easily use node libraries directly (although you can still use them). That's the biggest downside when you first get started, but once you get a hang of it, it is so much effective. Review collected by and hosted on G2.com.

I recently started using the K6 performance testing tool for my software development projects, and I must say, I am thoroughly impressed. K6 is straightforward, with a simple and intuitive interface that makes setting test cases a breeze.

One of the things I like best about K6 is the flexibility it provides when it comes to defining performance test scenarios. You can create complex performance test scenarios with multiple requests, query parameters, and headers, making it possible to test even the most complex applications.

Another aspect of K6 that I appreciate is the detailed reporting. The tool provides a comprehensive report of the performance test results, including charts, graphs, and complex test statistics. This makes it easy to identify bottlenecks and areas for improvement in the application.

The fact that K6 is open-source and free to use is also a big plus. It saves me a significant amount of money compared to other performance testing tools that often come with hefty licensing fees.

Overall, I would highly recommend the K6 performance testing tool to anyone looking for an easy-to-use and flexible solution for testing the performance of their applications. Its advanced features and detailed reporting make it an excellent tool for ensuring that your applications are running at their best. Review collected by and hosted on G2.com.

First and foremost, I found the interface extremely clunky and challenging to navigate. I struggled to find the needed features, and even when I did, I often had trouble figuring out how to use them. This made the entire testing process much more time-consuming and frustrating than it needed to be.

Another issue I had with K6 was the lack of customization options. I needed to test specific scenarios, but the tool didn't allow me to do so. I was stuck with a one-size-fits-all approach that didn't meet my needs. Review collected by and hosted on G2.com.

K6 is great for getting actual data on how your application is performing and can tell you exactly what your metrics and baselines should be. This is vital to any sort of SRE based organization. Review collected by and hosted on G2.com.

You do have to know how to use javascript in order to use k6, which makes it much more flexible and is incredibly easy to use. If you do want something that only works in UI, this might not be the tool for you. Review collected by and hosted on G2.com.

Flexibility, Code Friendly and Scalability. Really easy to use compared to other tools we have in our stack like Azure Load Testing or Jmeter. Review collected by and hosted on G2.com.

Some azure integrations are lacking and should be improved. Review collected by and hosted on G2.com.

K6 provides all the components that we need to build relevant tests:

- recorder to easily build k6 scripts

- an efficient scripting library helping us to make our script robust and even create custom metrics out of our scripts.

The biggest advantage of K6 is the large number of output plugins...I can run tests, and send the testing data to Prometheus, InfluxDB, Dynatrace ...And more.

I'm a big fan of one of their extension: x6-distributed traces. it's so powerful to have an OpenTelemtry trace for each of the virtual users. Review collected by and hosted on G2.com.

I have not been able to test their browser-based testing tool. i would like to see the value and the challenge of building such tests.

The only thing that I was a bit disappointed is the fact that disttributed load tests are only available with the K6 cloud...in fact not really it's possible if using the K6 operator. Review collected by and hosted on G2.com.

very efficient - can run alot of VUs on a machine

easily scalable - distributed k8s testing

ability to define stages & scenarios

ability to define custom metrics and checks

ease of use

Browser extension is still not quite there yet Review collected by and hosted on G2.com.

I like the easy to set up approach.

The developer friendly approach of the solution.

Lots of documentation and support.

Shift left approach and align with devops. Review collected by and hosted on G2.com.

It can be daunting for some testers with no developer experience.

It can become a coding nightmare if not careful with best development practices.

You can get lost if you are not documenting. Review collected by and hosted on G2.com.

-Excellent documentation and supportive blogs (and video content like the Office Hours series) content simplifies getting started with k6

-Developer-friendly -- Easy to install and get going in the CLI. Makes performance testing more accessible to not just a few, but all of those on an engineering team. This is so important as performance testing is no longer just an expectation of a single niche quality team because of limitations of licensing or knowledge of an antiquated tool.

-k6 cloud -- So far, ensuring the ability to scale our tests beyond the resource of our machines has been reassuring. The analyses and comparison features between test executions is helpful so far. Looking forward to the continued work against this infrastructure platform. Review collected by and hosted on G2.com.

-The user experience of using k6 with npm modules is not consistent with what you expect from typical development

-xk6 extensions conceptually are great as a community is helping to build out a need. Just be cautious of utilization as they may not be supported long-term, though these extensions are featured in k6 documentation. Review collected by and hosted on G2.com.
