loadimpact/k6 repository overview

THIS IMAGE IS DEPRECATED and its support will be discontinued after Dec 31, 2023. This image has been replaced by grafana/k6⁠.
Please update your scripts to use grafana/k6⁠ to continue using the latest version of k6.

k6 is a modern load-testing tool, built on our years of experience⁠ in the performance and testing industries. It provides a clean, approachable scripting API, local⁠ and cloud execution⁠, flexible configuration, with command & control through CLI or a REST API⁠.

This is how load testing should look in the 21st century.
