Grafana k6
Best developer experience for load testing.
Grafana k6 is an open-source load testing tool and cloud service for engineering teams. It helps teams verify that applications can handle expected traffic and identify performance issues before they reach production. Tests are written in JavaScript and can run locally, in Kubernetes, or in the cloud using the same script.
k6 supports load testing, end-to-end web testing, synthetic monitoring, fault injection testing, infrastructure testing, and regression testing. It works with APIs, GraphQL, cookies, WebSocket, and gRPC, and can run tests from multiple load zones. Integrations include Postman, New Relic, Visual Studio, Grafana, IntelliJ IDEA, and Datadog, with extensions for Kubernetes, Prometheus, Pub/Sub, Amazon SQS, Kafka, and OpenTelemetry.
k6 is aimed at developers, backend and frontend engineers, site reliability engineers, and software engineers in test or QA. It is available as an open-source tool and as a cloud service, with the same scripts usable across local, distributed, and cloud environments.
