Grafana k6 is **load testing for engineering teams**. **The best developer experience for load testing**: open source and SaaS for engineering teams.

- **Test early and continuously—break the QA silo in performance testing.** Developers, Backend and frontend engineers prevent regressions when running performance tests. Site Reliability Engineers test scalability to improve your reliability targets, test SLOs and avoid SLA breaches. Software Engineers in Test / QA shift left and collaborate with developers for effective and continuous testing.

- **Script tests in Javascript** for API, GraphQL, Cookies, WebSocket, and gRPC, with threshold config.

- **On your machines, our cloud, or both.** Scale from solo developers to large enterprises. Use the same script for local, distributed, and cloud tests. Migrate from local tests to the cloud using the same script for both environments.

- **Run tests from 21 load zones** to simulate real global traffic patterns.

- **More testing with one tool.** k6 Open Source is designed for load testing. Extensible to support other types of testing, including load testing, end-to-end web testing, synthetic monitoring, fault injection testing, infrastructure testing, and regression testing.

- **Integrations and Extensions.** k6 integrates with your dev tools. Extensions add new capabilities to k6.
