Grafana k6 is an open-source load testing tool for developers and DevOps teams that uses JavaScript to define test scenarios.
Grafana k6 is a developer-centric load testing tool built for scripting performance tests in JavaScript or TypeScript, enabling teams to run load tests from CI/CD pipelines or the command line without managing complex infrastructure.
Originally created in 2016 as an independent open-source project, k6 was acquired by Grafana Labs in 2021 and integrated into the Grafana observability platform. It supports Kubernetes-native testing and can send metrics to Grafana dashboards for real-time performance visualization.
