k6

brew install k6 v2.0.0 AGPL-3.0-or-later

Go-based load testing tool that runs JavaScript test scripts for performance benchmarking.

Why you might care

k6 lets you write load tests in JavaScript (familiar to many teams) and execute them as compiled Go binaries—no runtime overhead. It's purpose-built for CI/CD integration, cloud-scale testing, and real-time metrics collection, making it far simpler than JMeter or locust for modern web services.
