It is developer friendly and easy to write load tests and has excellent documentation.
Most importantly it is a straightforward K6 report that can tell where the performance issues are.
We did a thorough analysis where we compared several tools/frameworks and we can tell with full confidence that K6 is much superior compared to other tools.
These are some of the benefits:
It is easy to install and start writing the first L&P test, code review
It is great community support and excellent documentation
Excellent Report and Integrates with NewRelic, CloudWatch
if we decide to retire later it is easy to do because we can still run locally without being locked to one tool.
I would call the K6 a modern L&P framework that can beneficial for any company. Review collected by and hosted on G2.com.
I wish it had better support for HTTP protocols.
It is awesome with API test but not so great with UI load test. Review collected by and hosted on G2.com.
It's ease of use, readability and its fantastic set of constantly evolving features, paired with a vibrant community - which together with its good performance makes, to me, the best option for performance testing.
And its extensibility as well...
Tests are code, as they should. And readable code! Review collected by and hosted on G2.com.
There is an extensibility /plug-in system but some integrations are still not covered… 😅
To complain about something, its only issue is that apart from the excellent readability of the tests, they still need to be written, so you need to know what you are doing- thank god- I still have a job. But give it time… (summary: tests needs to be written, haha)
And the fact that you have to write in JavaScript - it would be fantastic to write in your own language such as C# as in my case :) Review collected by and hosted on G2.com.
I love that you can program instead of a user-level application
- You can use both JS and TS
- A multitude of thresholds to check the performance of our API
- It can be integrated with Azure pipeline, which automates the CI process much more
- It has spectacular and very fast technical support
- Almost perfect documentation
- Easy installation Review collected by and hosted on G2.com.
- More examples in the documentation
- More examples with Azure Pipeline Review collected by and hosted on G2.com.
You can load tests, stress tests, etc. you can. Having a JS-based structure makes it very easy to write your tests. You can find all the integrations with very good documentation from the documentation and try them immediately. If you want to see more advantages and a small example, you can review my article.

It supports almost any tool for real-time monitoring (Grafana, Newrelic, etc.). Since it is under the roof of Grafana, you are integrated into a very good monitoring system.
Identify your company's needs and integrate instantly. It's that simple, you don't need to deal with extra requirements like other tools. Review collected by and hosted on G2.com.
An improvement can be made so that we can export the metrics we want. handleToSummary does not fully meet the expectation. Review collected by and hosted on G2.com.
k6 OSS is a free and open-source solution for the modern development environment to get started with the load testing without leaving the IDE. You can write scripts in JS, and the execution engine in Go uses less memory footprint compared to other solutions in the industry. k6 documentation and the vibrant community helps to get started with k6 quickly. Numerous examples covering various scenarios are already present in the help. Using a little bit of knowledge on JS is sufficient to get started with k6 scripting. If you are coming from pure QA background, then learning k6 might be overwhelming, but the documentation is a one-stop-shop. Review collected by and hosted on G2.com.
Wish k6 OSS has a feature to scale the load using multiple load generators. Apart from built-in protocols, it is possible to extend the functionality using the k6 extensions. But the knowledge of the Go and k6 ecosystem is required. I am expecting more built-in protocols from k6 team. Review collected by and hosted on G2.com.
K6 lets us test the very critical phases of the application program interface lifecycle with its load and regression testing utilities. They literally have very handy docs which makes the process of setting up the initial setup so smooth. All the examples in the docs given by the team are really appreciative and to the point. Review collected by and hosted on G2.com.
In the process of regression testing, sometimes for long-quantity user engagement, the K6 request becomes a little slower. Yes, it depends on the machine of the user but a significant amount of time gets lost in order to restart the test after the lags. Review collected by and hosted on G2.com.
K6 is a cloud-native tool focused on automation and load test; that is the reason I have been working with it in my last job as a Performance Engineer, as well as my current position as an SRE in a real estate startup.
We leverage the power of Go to impact our endpoints with forcefulness, to measure the latency and reliability in our business flows, and give the dev teams the trust to ship a reliable product to market. As I said before, k6 is an essential tool in our box for executing our CI/CD. Review collected by and hosted on G2.com.
We are missing the capability of writing in files through js since there are some scenarios where we have to create .csv files from the javascript when a Body Response is received. Review collected by and hosted on G2.com.
I think the main advantages include:
- Low entry-level,
- Outstanding performance, thanks to the Go-based engine,
- Excellent documentation,
- Constantly growing community, additionally caring about the framework development. Review collected by and hosted on G2.com.
To be honest, it's hard for me to mention anything. Review collected by and hosted on G2.com.
It is really very helpful in doing performance testing of our API's. Very intuitive to understand. Review collected by and hosted on G2.com.
I find integrating web socket based for load testing really difficult through k6. It would be great if it could be improved. Review collected by and hosted on G2.com.
K6 is a very simple yet powerful Performance Tool. You can start your performance test in minutes from the Terminal. We have used it numerous times to make sure our applications meet the standards agreed with our customers. Review collected by and hosted on G2.com.
The only downside that I see is the fact that there are no graphical user interface to interact with the tool, you have to be comfortable with using the Terminal. Review collected by and hosted on G2.com.
