Looking for a LoadRunner alternative?

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 can develop very dinamic 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 our projects' performance trends.

Overall, k6 strikes a good balance between scripting flexibility and execution performance. k6 also offers a comprehensive ecosystem beyond the test runner.

The success of a performance testing tool in large projects hinges on how it can be shared. k6 open source engine model is the key to achieve this. At the same time, its commercial cloud scaling enables you to push your application to its limit. k6 Javascript tests allows you to develop complex tests and debug performance problems across your organization. The engine is modern; you can feel the maturity of the design and its APIs. The Cloud user interface is intuitive and powerful. This praise would not be complete without underlining how quickly you can get up a running; in part to the efficient documentation and great support.

I found that K6 has low footprint in RAM and CPU consumption. Also K6 allow us to share the coding with developers, either Frontend or Backend programmers, since K6 scripts are written in Javascript. And I saw that I don't need to worry about heap sizes, as Golang leverages all the RAM and CPU power in a native way.

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.

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.

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.
