## What it is
A fast HTTP/1.1 benchmarking and load-testing tool written in Node.js, inspired by wrk and wrk2. It can be used from the command line or programmatically via its API, supporting HTTP pipelining, HTTPS, and worker threads.

## Use cases
- load test an HTTP API before production
- benchmark my web server's requests per second
- compare performance of Node.js frameworks
- stress test an endpoint with concurrent connections
- run HTTP benchmarks in CI
- measure latency percentiles for an HTTP service

## When to choose
- you need a fast, scriptable HTTP benchmarking tool in Node.js
- you want to generate more load than wrk or ab
- you need programmatic load testing via a JavaScript API
- you want HTTP pipelining or HTTPS support in benchmarks

## When to avoid
- you need HTTP/2 or gRPC load testing
- you need a distributed load-testing setup across multiple machines
- you are benchmarking non-HTTP protocols

## Facets
- artifact type: cli-tool
- maturity: stable
- function: load-testing, benchmarking, http-client, cli
- domain: developer-tools, testing, performance, web-development
- platform: cli, cross-platform
