wrk: A Lightweight CLI Tool for API Load Testing
wrk is a modern HTTP benchmarking tool that generates load from a single multi-core machine using threads and event loops. It measures throughput and latency under stress, answering how many requests per second an endpoint can handle and how tail latency behaves. The tool is installed via Homebrew on macOS or built from source on Linux.

Wrk is a practical, no-frills utility for developers who need quick performance baselines, but it lacks functional verification and should be paired with proper API testing tools.
