**k6** is a modern load-testing tool, built on [our years of experience](https://k6.io/about) in the performance and testing industries.
It's built to be powerful, extensible, and full-featured. The key design goal is to provide **the best developer experience**.

Its core features are:

- **Configurable load generation.** Even lower-end machines can simulate lots of traffic.
- **Tests as code.** Reuse scripts, modularize logic, version control, and integrate tests with your CI.
- **A full-featured API.** The scripting API is packed with features that help you simulate real application traffic.
- **An embedded JavaScript engine.** The performance of Go, the scripting familiarity of JavaScript.
- **Multiple Protocol support**. HTTP, WebSockets, gRPC, Browser, and more.
- **Large extension ecosystem.** You can extend k6 to support your needs. And many people have already shared their extensions with the community! [Explore](https://grafana.com/docs/k6/latest/extensions/explore) the available extensions.
- **Flexible metrics storage and visualization**. Summary statistics or granular metrics, exported to the service of your choice.
- **Native integration with Grafana cloud**. [SaaS so
