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.
