k6 is an open-source load testing tool developed by Load Impact, designed specifically for developers to handle performance testing with a focus on simplicity and scalability. Launched in February 2017, k6 allows developers to write test cases in JavaScript, making it accessible and familiar while avoiding the limitations of esoteric scripting languages or GUI-based tools. The tool integrates seamlessly into continuous integration and delivery pipelines, supporting automation. To handle time series metrics, k6 leverages InfluxDB, and for visualization, it uses Grafana, known for its flexible dashboards. The community has contributed various dashboards to enhance k6's usability. In addition to its open-source version, k6 offers a SaaS product, simplifying infrastructure and result storage management, akin to Grafana Labs' model. k6 aims to be the preferred tool for developers by ensuring performance stability amidst rapid development cycles.
