xk6 is a command-line tool for building k6 with extensions written in Go, similar to how xcaddy builds Caddy. It scaffolds new extension projects, compiles k6 binaries bundled with one or more extensions, runs and integration-tests the resulting binary, and lints extensions for compliance, without requiring you to fork or patch the k6 source itself.
