Explore k6 extensions

With over 50 available extensions, the k6 extension ecosystem has many options to meet your requirements and help you incorporate new protocol access, embed a particular client, or improve your test performance. Extensions are developed both by the k6 developers and by the open-source developer community.

Extensions are composable; you can combine any extensions, or mix and match different test cases. You can use Go and xk6 or Docker to build your custom k6 binary:

xk6 build \
  --with \
docker run --rm -u "$(id -u):$(id -g)" -v "${PWD}:/xk6" grafana/xk6 build \
  --with \

Use the table to explore the many extensions. Questions? Feel free to join the discussion about extensions in the k6 Community Forum.
