About
k6 is an open-source performance and load testing tool developed and maintained by Grafana Labs that allows engineering teams to write test scripts in JavaScript, execute them from the command line or within CI/CD pipelines, and analyze results through a rich metrics output layer that integrates natively with Grafana dashboards. The tool is designed from first principles around developer experience — scripts use a clean ES6 module syntax, test logic is expressed as plain code rather than through GUI recording, and the CLI output surfaces the key performance indicators teams care about without requiring a separate analytics platform to interpret results. k6 ships with built-in support for HTTP, WebSockets, gRPC, and browser-based scenarios, covering the range of protocols used in modern web and microservices architectures without requiring separate tooling for each protocol class.
