autocannon

An HTTP/1.1 benchmarking tool for Node.js, designed to be fast and easy to use. Current stable version is 8.0.0, released in late 2021. It supports HTTP pipelining, HTTPS, and can produce more load than wrk or wrk2. It offers both a command-line interface and a programmatic API, with features like warm-up, worker threads, HAR file replay, and custom request bodies. The project is actively maintained by the Node.js community.
