An extensible load testing tool built for developer happiness
For modern engineering teams. The k6 API and CLI are designed to be intuitive, flexible, and powerful.
Integrate performance tests in your CI/CD tool and set up pass/fail criteria to ensure reliability goals. Proactively test your SLOs.
The k6 engine is written in Go making it one of the best performing load testing tools available.
"Big Tent" interoperability is in our DNA!
k6 can output test results to various backends like DataDog, Prometheus, NewRelic, Timescale, etc.
Community extensions open new options to test infrastructure's performance: SQL, Browser, Kafka, Kubernetes, Chaos, MQTT, and more.
Build and debug locally, scale to the cloud. Run the same test on your local machine, in a distributed cluster, or k6 Cloud.
