A modern load testing tool built for developer happiness
For developers by developers. The k6 API and CLI are designed to be intuitive, flexible, and powerful.
Designed for automating your performance tests. Use your performance goals as the pass/fail criteria.
Great on its own - even better when integrated! k6 is easily integrated with common CI tools and can also output test results to various backends and formats like DataDog, Kafka, CloudWatch, NewRelic, JSON and CSV.
The k6 engine is written in Go making it one of the best performing load testing tools available.
Designed to scale. Use the same tests on your local machine, in a distributed environment, or in the cloud. A unified experience for various execution modes.
Verify that your systems can handle the expected volume of visitors. Traffic is rarely consistent. Quickly adapt your scripts to run various types of testing: stress tests, peak tests, soak tests, and more.
Simulate real-world traffic in your chaos experiments. Ensure that your environment is able to withstand traffic surges without outages, gracefully recovering as components fail.
For ambitious applications, ping testing is not enough anymore. Reuse your tests that mimic user traffic to further monitor the availability and performance of your systems.
