## What it is
A Node.js CLI tool and library that runs load tests against HTTP or WebSocket URLs, with an Apache ab-compatible interface plus a --rps option to force a constant requests-per-second rate. It also exposes an API for integrating programmatic load tests into automated test suites.

## Use cases
- load test a URL with configurable concurrency and request count
- simulate a sustained requests-per-second rate against a web server
- measure mean response times before deploying a new version
- run programmatic load tests as part of systems tests via the API
- load test WebSocket endpoints
- replace Apache ab with a more tweakable alternative

## When to choose
- you want an ab-compatible load tester with forced rps control
- you need to embed load testing in Node.js test workflows
- you need to test HTTP or WebSockets endpoints quickly from the CLI

## When to avoid
- you need distributed load generation from multiple machines
- you need rich scripting scenarios or UI-level browser load testing
- you are not in a Node.js environment
