# What is Load Generator?

*Development · Last updated: September 30, 2026*

A tool that generates artificial user traffic to measure how much traffic a system can handle.

## Overview

Imagine thousands of people accessing the site at the same time before your software projects go live. You can't wait for real people to test this situation; This is where the load generator comes into play. It throws out artificial requests to push your system to its limits and see where it will crash.

***Analogy:** They are like testing machines that release thousands of model cars onto the road at the same time to test the durability of a newly opened highway.*

## How it works

It works by commanding the target website or server to click, send data, or make requests in a short period of time. It reports the responses received and the server's reaction under this pressure.

## Where it is used

It is frequently used in stress tests, server capacity planning and performance improvement processes before websites are launched.

## Commonly confused with

It can be confused with penetration testing tools for finding security vulnerabilities; The purpose here is not to break the system, but to weigh how much load it can carry.

## Questions and answers

**How does it differ from real user traffic?**

It is completely automatic and repeats predetermined scenarios much faster and more voluminously than humans.

**Could it crash the system?**

Yes, if you exceed the capacity limit you can temporarily slow down or crash the system under test.
