About:
xk6 is a command-line tool and SDK for building custom versions of the k6 load testing binary with community and third-party extensions. It acts as a build wrapper, enabling developers to integrate new protocols and output formats without maintaining complex build toolchains. This allows teams to tailor k6 to their specific performance testing requirements.
Key Features:
  • CLI tool for compiling custom k6 binaries
  • Go-based SDK for developing extensions
  • Seamless integration with existing k6 APIs
  • Supports community and private extensions
Use Cases:
  • Adding custom protocol support (e.g., Kafka, MQTT) to k6
  • Integrating proprietary monitoring or logging backends
  • Creating a bundled k6 binary for standardized CI/CD pipelines
Alternatives:
  • k6-core – xk6 is the official, community-focused extension system, whereas k6-core is the base engine for internal development.
