Thousands of teams and developers use k6 every day. Read their use cases and stories.
We can develop very dynamic scenarios with all the logic and customized metrics that one can think of. The k6 open source platform is quite straightforward and its configuration are fairly easy to implement in our scripts. Running scalable tests locally or using the cloud support is a breeze. k6 Cloud provides us with great knowledge and real-time graph to analyze every detail of our projects' performance trends.
Performance and reliability of our platform are of the utmost importance for Olo, our brands, and our partners. As a result, k6 has become an integral part of our test stack. k6 helps us quickly experiment with new ideas and verify that releases are production-ready.
We love the flexibility of k6. It can be adapted to provide whatever information we need, no matter how unique to our platform the situation is. We now have a performance testing framework which tells us exactly what our teams need to know and keeps a watchful eye on our code base for any performance issues that might slip in.
Overall, k6 strikes a good balance between scripting flexibility and execution performance. k6 also offers a comprehensive ecosystem beyond the test runner.
Very good load testing platform. We as a retailer got tremendous help with the load testing to survive Black Friday 2019. Biggest plus is that the tests can be run from command line, and are configured with code.
k6 Cloud Enterprise has enabled our quality engineering team to build more confident testing and streamline the process for deployment of new features and products, creating an all-around first-class experience for our customers.
I have used other testing tools like Apache Benchmark, Jmeter, Gatling, and Postman, but k6 outshines them all with its ease of writing workflows using various operations provided by a service. Adding field validations, asserting outputs, generating dynamic dataset, and debugging the tests were all likewise very easy compared to other tools I have used in the past.
The engineering effort of writing tests for just one of our microservices was going to be 2+ Engineering weeks in JMeter, versus the ½ day it took us in k6!
I'm very impressed by k6. I've tested a few load testing tools before, but k6 is by far the fanciest. 🎉
I would gladly recommend this to anyone needing to load test their endpoints. We were using Gatling at work to do load testing and it was very slow to develop in it as we were lacking experience in scala. We found this and never looked back. The impact it had on benchmarking, profiling and tuning the servers was massive. I’m pretty sure the company saves a few thousand dollars every month till today because of those optimizations.
"To my opinion the best performance test tool, framework & ecosystem for developers"
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!
"Why is k6?"
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.
"Easy to get started and less memory footprint"
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.
"One of the best API load testing tool"
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.
"As a former Performance Engineer and a new SRE, k6 is my combat tool"
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.
