Extensions

With k6 extensions, you can extend the core k6 functionality with new features to support your specific reliability-testing needs.

k6 supports three types of extensions:

  • JavaScript extensions extend the JavaScript APIs available to your test scripts. They can add support for new network protocols, improve performance compared to equivalent JS libraries, or add features.
  • Output extensions send metrics to a custom file format or service. They can add custom processing and dispatching methods.
  • Secret Source extensions provide secrets to your tests.
